(TU Delft Architectural Technology)","","2024","The urgency of addressing housing challenges in low-income areas is increasing due to widening socio-economic inequalities and the worsening impact of natural disasters. Saint Martin, a small Caribbean island, is struggling to provide affordable housing amidst hurricanes, floods, and heat waves. As a result, there has been a rise in self-organized housing units, which are built incrementally and are susceptible to risks. The main challenge is to balance durability, functionality, and esthetic appeal over time. Inspired by St. Martin’s self-organized units, this article explores housing considerations in low-income, hazard-prone contexts by emphasizing their temporalities. Integrating insights from a formative study, including a literature review and ethnographic research, the paper draws on Stewart Brand’s “Layers of Change” and the concept of “Flow”. The study identifies layers within self-organized units corresponding to durability, functionality, and esthetic appeal. It delves into their connection with building activities over time, unveiling the temporalities of housing considerations. This exploration leads to the proposition of “Designing for a Flow” as a novel design approach. Offering practical insights within a concise framework, the study provides nuanced perspectives on mitigating housing challenges in low-income and hazard-prone contexts.","incremental housing; low-income housing; resilient design; climate change; extreme weather; layers of change; Stewart Brand; sustainability","en","journal article","","","","","","","","","","Management in the Built Environment","Architectural Technology","","",""

Design: Cross-sectional survey. Setting: An academic hospital in the Netherlands. Population: Gynaecologists, surgeons, residents and operating room assistants (n=80). Methods: Quantitative and qualitative data were obtained via a written questionnaire. Participants provided subjective comments and scored the reusable gown on each individual topic with a score from 1 to 5 (1 = unsatisfactory, 2 = moderate, 3 = good, 4 = very good, 5 = excellent) and compared the reusable gown with the conventional disposable alternative (better, equal or worse). Main outcome measures: Wearing comfort: ventilation and temperature regulation, fit and length, functionality, barrier function and ease of use. Results: The results of the overall scores of the reusable gown are scored as ‘very good’ (mean 4.3, SD ± 0.5) by its users. Regarding comparison of the gowns, more than 79% (lowest score 79%, highest score 95%) of the participants scored the reusable gown equal or higher on six of seven topics. The topic ‘ease of use’ was scored equal or higher by 59% of the participants. Subjective comments provided information on possible improvements. Conclusions: The findings of this study demonstrate that there is professional acceptance regarding the utilisation of reusable surgical gowns. To facilitate broader adoption, it is imperative to foster collaboration among suppliers and healthcare institutions. The reusable surgical gown is an environmentally sustainable, safe and comfortable alternative in the operating room.","climate change; comfort; operating room; surgery; surgical gowns; sustainability; user experience","en","journal article","","","","","","","","","","","Medical Instruments & Bio-Inspired Technology","","",""

Around this central question, this dissertation examines how Shanghai's coastal and waterfront developments have changed over the past two decades under the influence of shifts in Chinese state capitalism towards what is called an Ecological Civilization. Two cases along the waterfronts of Shanghai – one on former docklands in Shanghai’s Central City, and one on peri-urban Chongming Island ¬– have been examined to test how both lines of thinking can enrich each other, and if a sustainable transition can be done more efficiently and convincingly in a centrally controlled society than in a non-autocratic (liberal) society. What lessons does the Chinese approach in Shanghai offer for elsewhere, and how can different approaches and practices reinforce each other in spatial planning and strategies for a sustainable transition? This dissertation emphasizes that ecological civilization thinking can offer hopeful starting points for sustainable transitions but can only work well if sufficient 'checks and balances’ are included. It gives suggestions to improve the accessibility, inclusivity, and vibrancy of Shanghai’s waterfronts, and to mitigate ecological degradation in the context of an urban delta.","energy transition; socio-technical change; sustainability; urban delta; urban planning; Waterfront Regeneration; Sustainable transitions; Ecological civilization; China; National Demonstration Projects; Experiments","en","doctoral thesis","","978-94-6366-744-9","","","","","","","","","Spatial Planning and Strategy","","",""

It focuses on the Politiebureau Groningen Centrum (The Netherlands) as a case study to apply a novel approach to engage community participation in architectural redesign. It fills the academic gap on participation in heritage building redesign lacking diversity in stakeholder perspectives and overcomes some of the current participatory design tools’ downsides, identified in the previous literature: lack of transparent communication and high requirement for participants. This research employs a combination of methods structured by sets of divergent and convergent phases. Cognitive mapping, semi-structured interviewing, and a 2,5D model game were tested in the research for inquiry and redesign testing, the two key participatory stages. The research outcomes include participants’ perceptions and remembrance of the site for generating redesign scenarios, the common ground in their scenario preferences, and their contrasting attitudes toward the overall material and the specific elements. The 2,5D model game tool turns out effective in transparently delivering the redesign possibilities to participants and lowering the requirements of time, language skill, and learning capacity, thus being easily repeatable for other sites and participants to boost social and community values. Future research recommendations are given on applying the approach to larger samples covering all the minorities to get in-depth knowledge on the community’s collective perspectives in relation to their sociodemographic characteristics and validate the hypothesis on their preferences toward materials and elements.","sustainability; heritage redevelopment; participatory design; public engagement; community value; social value; Faro Convention; HUL; heritage; cognitive mapping","en","journal article","","","","","","","","","","","Heritage & Architecture","","",""

(Student TU Delft); Petrick, Kristian (Airborne Wind Europe); Wilhelm, Stefan (Ampyx Power); Schmehl, R. (TU Delft Wind Energy)","","2023","A key motivation for airborne wind energy is its potential to reduce the amount of material required for the generation of renewable energy. On the other hand, the materials used for airborne systems’ components are generally linked to higher environmental impacts. This study presents comparative life-cycle analyses for future multi-megawatt airborne wind energy systems and conventional wind turbines, with both technologies operating in the same farm configuration and under matching environmental conditions. The analyses quantify the global warming potential and cumulative energy demand of the emerging and established wind energy technologies. The cumulative energy demand is subsequently also used to determine the energy payback time and the energy return on investment. The selected airborne wind energy system is based on the design of Ampyx Power, using a fixed-wing aircraft that is tethered to a generator on the ground. The conventional wind turbine is primarily based on the NREL 5 MW reference turbine. The results confirm that an airborne wind energy system uses significantly less material and generates electricity at notably lower impacts than the conventional wind turbine. Furthermore, the impacts of the wind turbine depend strongly on the local environmental conditions, while the impacts of the airborne wind energy system show only a minimal dependency. Airborne wind energy is most advantageous for operation at unfavourable environmental conditions for conventional systems, where the turbines require a large hub height.","airborne wind energy; wind farm; life-cycle assessment; renewable energy; sustainability","en","journal article","","","","","","","","","","","Wind Energy","","",""

Renovating the social housing stock to attain the built fabric standards introduced in the European Directive on Energy Performance of Building(EPBD) will require the mobilisation of both public and private funding as envisioned by the European Commission in the Renovation Wave. In this landscape of increased investment needs, Environmental, Social and Governance (ESG) standards have risen to a prominent
position as the main indicators of sustainable investment. While ESG-earmarked funds have grown significantly in the last years, there is widespread concern about the real impact of ESG-funded projects and whether these are in fact bringing additional investment into key transitional activities such as the renovation of the social housing stock. This project poses two questions, first, How does ESG funding interlock with the renovation strategies of social housing providers? And second, How do institutional factors affect the uptake of ESG funding? To answer these questions, this project draws from semi-structured interviews with finance officers from housing providers across six European countries with large social housing stocks: Austria, Germany, The Netherlands, France, Sweden, and the UK. The main objective of this paper is to critically assess the contributions of ESG funding to the energy transition and contextualise it within traditional forms of private and public financing of social housing.","ESG; social housing; energy transition; green finance; sustainability","en","abstract","","","","","","","","","","","Urban Development Management","","",""

(TU Delft System Engineering)","","2023","Challenges involving economic, environmental, and societal aspects necessitate organisations in business networks to collaborate. The scientific problem central to this paper is the difficulty of building sustainable collaborations. The research question is how to support organisations in building sustainable collaborations in their business relationships. This paper presents a new socio-technical approach to this end, i.e., PDPS (an acronym for Participatory Design of Participatory Systems) and explores its potential in a case study. PDPS is a value-based approach to the participatory design of participatory systems. Such socio-technical systems enable people working in different disciplines, departments, and organisational levels to create sustainable relationships supported by distributed information and communication technology. In a participatory system, participants gain trust, engagement, and empowerment to self-organise actions that produce results they could not have achieved alone. Following PDPS, participants collectively explore challenges in their relationship, define a joint value-based mission, and create a continuous process of self-organisation to fulfil this mission. In a case study, PDPS supported two Dutch business partners in solving recurring transport and logistics issues in retail store refurbishment projects. Turning their traditional business processes into participatory ones led to new solutions for sustainable transport and logistics, more joint business, and more profit. PDPS differs from other approaches in its involvement of all participants in a business relationship, its focus on shared values, and its capacity for creating a continuous process of self-organisation to fulfil a joint mission. This paper may support researchers, practitioners, and organisational policymakers interested in building sustainable collaborations in business networks.","business network; collaboration; complex systems; design thinking; participatory design; self-organisation; sustainability; systems thinking; value-sensitive design","en","journal article","","","","","","","","","","","System Engineering","","",""

The input to the digital twin combines monitoring of the information and communication technology infrastructure used for graph processing with data collected from the power grid.

This research presents an experimental programme to assess the durability of epoxy-modified open-graded porous asphalt (EMOGPA) mixes, emphasising the effects of the reactivity of two mineral fillers on mixes containing various EA proportions. Results indicate that the EMOGPA mixes have shown a high sensitivity to the conditioning time before compaction (aka. preconditioning). The materials produced exclusively by EA are the most sensitive to preconditioning, reducing their water and ravelling resistance with increased preconditioning time lengths. The number of gyrations has also been proven as an efficient quantity of the compaction effort required to reach the target mix properties. Moreover, the proportional increase of EA in mixes led to substantially improved durability. Hydrated lime in epoxy-modified asphalt mixes also affected their mechanical response. The indirect tensile strength and toughness of EA mixes were higher than other mixes, while mixes with limestones were stronger and tougher than those with hydrated lime. This attribute reflects the positive contribution of apolar fillers to strengthen and toughen the EA mixes.","Open-graded porous asphalt; epoxy asphalt; filler; durability; longevity; sustainability","en","journal article","","","","","","","","","","","Pavement Engineering","","",""

While the development of recycled metals is in its early stages, the use of probiotics and renewable polymers to improve the biofunctionalities of bone implants is highlighted. Despite the advances of additive manufacturing (AM), studies on AM waste-derived bone-substitutes are limited. It is foreseeable that AM technologies can provide a more sustainable alternative to manufacturing biomaterials and implants.

But there is a lack of understanding of whether the groundwater system can sustain the growing demand in the future amidst climate change and rapid urbanisation. Using remote sensing datasets and a water balance approach, this study estimated the groundwater recharge and assessed how urbanisation has affected its groundwater sustainability. Sustainability is investigated by comparing multi-annual groundwater withdrawals to long-term average annual replenishment. Results show that while groundwater recharge has decreased by 80% from 1986 to 2020, mainly due to substantial (63%) loss of permeable land, groundwater consumption has seen a six-fold increase. Groundwater consumption in 2020 exceeded the long-term average groundwater recharge by 2.2Mm3, suggesting that the current groundwater use trends are unsustainable for future ground-water availability. Under a ‘business-as-usual’ scenario, a four-fold increase in groundwater consumption is predicted by 2050 while climate change and land-cover changes may reduce groundwater recharge by 10% and 55% respectively. Practical measures such as promoting artificial groundwater replenishment approaches, adopting low-impact development and instituting demand management measures must be implemented in the Metropolis. This should be informed by further studies to ascertain the exact condition of the groundwater.","groundwater; Kumasi; remote sensing; sustainability; urbanisation; water consumption","en","journal article","","","","","","","","","","","Water Resources","","",""

(TU Delft Architectural Technology)","","2023","Recent natural disasters and climate change-induced extremes emphasize the urgent need to enhance the overall resilience of society by addressing the various hazards that buildings may face. Current design approaches recognize the need for integrated risk assessments, but studies primarily focus on existing buildings and single hazards, neglecting the impact of multiple hazards and resilience quantifications. However, it is crucial to consider multi-hazard scenarios and quantify economic, environmental, and resilience losses to pursue effective solutions from the early-stage design of both new buildings and retrofitting interventions. This paper presents a practical multi-criteria approach to support design decisions for enhanced safety, sustainability, and resilience of buildings against earthquakes and heatwaves. The proposed approach is applied to a commercial building with various seismic-resistant and energy-efficient facades. Non-linear seismic assessments are conducted to predict the potential impact concerning repair costs, carbon emissions, and the resilience loss at the design-level earthquake. Additionally, a whole life-cycle analysis and dynamic energy simulations are performed to calculate the financial and carbon losses resulting from power consumption and the ability of the building to maintain energy efficiency under extreme heat. Finally, the study employs a multi-matrix decision-making approach based on integrated economic, environmental, and resilience losses to guide the design selection. The results demonstrate that earthquake-resistant facades can significantly reduce financial losses by over 50%, with seismic resilience playing a crucial role in the final decision. This approach facilitates more effective investment decisions for building projects, enabling the quantification of the effectiveness of integrated strategies in reducing overall potential losses.","resilience; performance-based design; earthquakes; heatwaves; energy efficiency; sustainability; economic loss","en","journal article","","","","","","","","","","","Architectural Technology","","",""

These problems are the result of industrialization in all fields. The textile and fashion industries bear a negative impact on the environment and contribute significantly to water, air, and solid waste pollution. Over the last decades, consumer buying habits have shifted, and clothing purchases have increased dramatically. The manufacturing process of these textiles, from pretreatment to dyeing and finishing, involves the use of numerous chemicals that are harmful to both humans and the planet. Textiles have been identified as unsustainable products due to their entire life cycle, from raw material cultivation to manufacturing, and generate a large amount of toxic waste and greenhouse gases. Therefore, embedding sustainability in strategy is essential to meet evolving investor pressure, consumer demand, and regulatory requirements. More alternatives are available, such as ecofriendly textiles. Governments are promoting the idea of ecolabels and sustainability standards that endorse the textile’s “ecofriendliness”. Ecolabeling stimulates consumers and manufacturers to buy and produce ecotextiles, simultaneously allowing consumers to compare the various products. Consumers are gradually requesting more ecofriendly products. To save our environment and future generations, the textile industry must become more sustainable. Major brands should implement sustainable manufacturing practices. This review paper investigates the requirements of ecofriendly textiles, restricted substances, and ecolabeling in the textile industry and highlights the need to enhance the expertise and information existing in the design process with regard to the sustainability of finished products in order to create a more sustainable textile sector. Such a shift is only feasible if the designers are guided by a clear vision of design for sustainability.","ecofriendly textile fibers; ecolabels; ecotextiles; fashion industry; product design; RSLs; sustainability; sustainable industrial manufacturing; textile industry","en","review","","","","","","","","","","","Team Yongxiang Yang","","",""

This paper aims to develop a methodology to study the impacts of common gradual changes occurring in the urban environment (densification of the urban area and implementation of blue-green infrastructure), forming cumulative transitions, on the functioning of real-time optimization procedures. A new generic methodology, relying on a comprehensive evaluation strategy based on three indicators assessing the continued optimal performance of RTC was proposed. This methodology was applied to two urban drainage catchments in Eindhoven and Rotterdam using both probabilistic and projected transitional paths. Based on the results obtained it can be noted that the performances of the RTC procedures were not strongly affected by the modeled transitions although the relative performance compared to the maximum performance potential decreases significantly with the large-scale implementation of blue-green infrastructure, indicating that the revision of RTC procedures could improve the sewer system functioning further. The relative performance loss associated with the modeled transitions was higher for model predictive control compared to heuristic RTC procedures for one case study and vice versa for the other. Continuous re-evaluation of the RTC strategy is, therefore, an important but overlooked part of the implementation of RTC procedures.","densification; longevity; real time control; sustainability; transitions; urban drainage systems","en","journal article","","","","","","","","","","","Sanitary Engineering","","",""

Engineered fractured systems, for example geothermal or carbon storage reservoirs, highly depend on the capacity of rock to conduct and store fluids. Faults and fractures create the largest contrasts in flow in these reservoirs and can enhance the reservoir potential when being generated or engineered. While the scientific focus is mainly on the effectiveness of enhancements and the risks associated with them, the sustainability of these enhancements must be better understood. In this thesis, the dependence of fracture permeability on a variety of parameters is studied. The aim is to develop a better systematic understanding of the hydro-mechanical processes controlling the potential and sustainability of fractures to conduct fluids at a variety of conditions. Several parameters that are assumed to control fracture permeability are considered in laboratory experiments. These include the rock type (clastic vs. crystalline), the fracture type (shear vs. tensile), the fracture geometry (aperture and roughness) and effective stress changes (pore and external stress). Potential geothermal rocks are considered in order to directly relate the findings to potential geothermal exploration projects. The results demonstrate the complex dependency on a variety of parameters and highlights the different physical processes depending on mainly rock and fracture type. An attempt was made to assess the potential of fractures to act as fluid conduits in reservoirs, as well their hydraulic sustainability during effective pressure changes. From these results, general implications are made concerning the ability and sustainability of fractures to conduct fluids depending on rock and fracture type. The main controlling parameters are assessed and possible mitigation strategies are developed to reduce the risk of permeability losses. Generally, only reservoir enhancement strategies resulting in a sustainable productivity increase can guarantee the scientific and political breakthrough of geothermal energy supply.","Fractures; sustainability; permeability; laboratory; geothermal","en","doctoral thesis","","978-94-6366-392-2","","","","","","","","","Reservoir Engineering","","",""

Cities try to grapple with these challenges but simultaneously find themselves locked in an intense competition with other cities. City branding is viewed as an essential strategy to remain competitive, improve their environmental performance, experience a sustainable urban transformation. However, very little is known about how cities actually implement city branding strategies. This study distinguishes the concepts in use and explores the evolution of research in place branding literature. A progressive relationship between city promotion, city marketing and city branding is proposed and empirically examined. Subsequently, a specific city brand is explored to study how different policy instruments are adopted and configured to realize urban transformation goals. Finally, a detailed investigation in a medium-sized Chinese city shows how stakeholders interact with city policymakers to create and implement city brands. The findings show that cities can apply promotion, marketing or branding strategies to achieve different urban development goals. The study concludes that to successfully implement city branding, extensive stakeholder participation, continuous political commitment and reasonable application of policy instruments are necessary.","city branding; Urban transformation; sustainability; Chinese cities; Policy implementation; Policy Instruments; Low carbon city","en","doctoral thesis","Delft University of Technology, TPM","978-94-6366-372-4","","","","","","2021-06-01","","","Organisation & Governance","","",""

At first sight, these concepts seem to pursue a complementary mission, yet, academic literature has not explicitly addressed their complementary nature. Therefore, this paper addresses this gap by reviewing, proposing and empirically exploring the merits of SNM and how these can be used in DT through a workshop to increase successful market implementation of sustainable innovations. The study finds that SNM potentially helps the DT design process to (1) change market preconditions for the design, (2) create a protected niche for development, (3) establish a (long term) commercial viability, and (4) create an innovation development plan through definition of a set of testable propositions. The paper concludes that the inclusion of SNM into DT substantially increases the preparedness of an innovation team for a successful market implementation of sustainable innovations and coins the term ‘Design to Market Thinking’ for the integrated use of SNM in DT.","Design thinking; innovation; market; strategic niche management; sustainability","en","journal article","","","","","","","","","","","Integral Design & Management","","",""

Common practices to limit proliferation involves use of disinfectants, leading to formation of disinfection by-product and increase in water corrosiveness. A disinfectant-free Legionella control method would make the industry more environmentally friendly. A pilot-scale cooling tower (1 m3/h) operated with demineralized water was used to investigate the potential of high-pH conditioning as a disinfectant-free alternative for control of L. pneumophila and other pathogens. One control experiment was performed under standard full-scale operation involving sodium hypochlorite dosage. Thereafter 3 alkaline pHs of the cooling water were tested: 9.0, 9.4 and 9.6. The tests lasted between 25 and 35 days. The cooling water from the basins were analysed for total cell count by flow cytometry, L. pneumophila concentration by plate count and occasional qPCR analyses targeting the mip-gene, bacterial and eukaryotic community analyses with 16S and 18S rRNA gene amplicon sequencing, relative abundance of eukaryotic to prokaryotic DNA by qPCR of the 16S and 18S rRNA gene. The L. pneumophila analyses showed considerable growth at pH 9.0 and pH 9.4 but was maintained below detection limit (< 100 CFU/L) at pH 9.6 without disinfection. Interestingly, the results correlated with the overall abundance of protozoa in the water samples but not directly with the relative abundance of specific reported protozoan hosts of Legionella. The pathogenicity based on 16S rRNA gene amplicon sequencing of the cooling water DNA decreased with increasing pH with a strong decline between pH 9.0 and pH 9.4, from 7.1% to 1.6% of relative abundance of pathogenic genera respectively. A strong shift in microbiome was observed between each tested pH and reproducibility of the experiment at pH 9.6 was confirmed with a duplicate test lasting 80 days. High-pH conditioning ≥ 9.6 is therefore considered as an efficient disinfectant-free cooling tower operation for control of pathogenicity, including L. pneumophila.","interaction; microbiome; pathogenicity; PCA; protozoa; sustainability","en","journal article","","","","","","","","","","","BT/Environmental Biotechnology","","",""

The existing literature still regards heritage conservation, urban management, circular economy and sustainable development as different spheres of knowledge. The Recommendation on the Historic Urban Landscape (HUL) provides a holistic approach to integrate these spheres, along with a supplementary toolkit. However, its implementation is still sporadic, not fully aligned with the circular economy framework, and unframed in the adaptive reuse and regeneration policies and practices at local level. The aim of this paper is thus to provide a framework to investigate how the HUL approach and tools are operationalised at building level, bridging the gap between international policy documents, global aspirations circular economy, and local practices of adaptive reuse. For this, the circular models of adaptive reuse in terms of governance and decision-making structures, and environmental strategies are identified through a case study analysis of best practice: the Pakhuis de Zwijger (PdZ) case in Amsterdam. Focus group meetings have been conducted with internal and external local stakeholders of PdZ to formulate their governance model, and four levels of sustainable governance actors are identified. Then, their decision-making process is mapped, and the newly adopted sustainability measures are analysed. These circular models and strategies at building level are then aligned with the broader HUL toolkit.In this context, this paper contributes to the operationalization of HUL tools at building level, supporting the strengthening of efforts for the protection of world’s cultural heritage (UN SDG 11.4) and reduction of waste generation through reuse (UN SDG 12.5)The identification and assessment of circular administrative and environmental models of adaptive reuse incorporates circular economy strategies and tools into the HUL framework.","Historic urban landscape approach; circular models; adaptive reuse; governance; decision-making; sustainability; Pakhuis de Zwijger","en","conference paper","TU Delft OPEN","","","","","","","","","Architectural Engineering +Technology","","","",""

(TU Delft Housing Quality and Process Innovation)","","2020","Housing pathology is the holistic approach to identify, investigate and diagnose housing deficiencies, specify preventive measures and remedial interventions and evaluate their effects. In analogy with health as the core condition for the quality of human life, the health of housing accommodations stands for housing quality, being the ability of residential buildings to fulfil adequate shelter for specified groups of residents.
The relevance of housing and building pathology as a relative new knowledge field lies in the paradigm shift from new construction to maintenance and adaptation of the existing housing stock that occurs in most western countries, but also in the fast growing urban areas in developing countries. To maintain the fast ageing housing stock in developed countries as well as to shelter the growing population in emerging economies in a durable and sustainable way, the service life span has to be optimally extended. The impending assignment to reduce the ecological footprint and CO2 and N2 emissions of the construction and housing sector – also a major paradigm shift - requires major adaptations of homes and services as well as of the mindset and behaviour of builders, managers and residents. For the implementation of the Paris Climate Action Agreement, knowledge based sustainable stock management and adaptation will be indispensable.
Though it is the combination and interference of technical, social, spatial and economical processes that is determining for the health and life span of housing stocks, they are hardly interdisciplinary studied nor integrated in practical knowledge, let alone in a pathological context. The existent theoretical and applied knowledge about the different fields of housing stock management – in particular life span, life cycle and quality condition management is up to now too limited and segmented to successfully fulfil the new assignments. Rearrangement in a comprehensive pathological domain appears as an obvious solution.
This paper defines and explores the knowledge the knowledge required for the coming assignment, overlooks the available knowledge and shortcomings, the field of application, the main diagnostic tools and instruments and the practice in housing management. The paper concludes with the necessity of better holistic, building type and behaviour directed pathological knowledge and further international interdisciplinary research cooperation.","building pathology; housing quality; housing management; life cycle management; sustainability","en","conference paper","","","","","","","","","","","Housing Quality and Process Innovation","","",""

The articles collected in this special section explore case studies from three continents. Together, they demonstrate that there is no such thing as the resilient (port) city. But, they also show that the combination of maritime and urban interests can lead to creative planning for resilience, particularly when port and city authorities pursue the same strategies. In view of contemporary challenges, this special section demonstrates the value of further research on port city resilience and vulnerability.

Therefore, there is a need for efficient in situ H2O2 generation methods. Here, we show that radiolytic water splitting can be used to promote specific biocatalytic oxyfunctionalization reactions. Parameters influencing the efficiency of the reaction and current limitations are shown. Particularly, oxidative inactivation of the biocatalyst by hydroxyl radicals influences the robustness of the overall reaction.

The more it grows, the higher the negative environmental effects and the more the use of space, resources, pollution and travel. Sustainable tourism aims to strike a balance between the environmental, economic and social effects of tourism. The aim of this article is to find the optimal itinerary for an individual traveller to a congress hotel in Valencia. The main research question is as follows: Which itinerary has the best overall score in terms of CO 2 per passenger kilometre, travel time and direct cost? Three scenarios were compared: Airplane plus, train plus and car only. The choice of these three suits the travel purpose and length. Literature was used to find the necessary trip and vehicle data. This was fed into a microsimulation model. The main outcome of the simulation experiment is that the environment would benefit if the traveller would favour the train plus scenario. This, however, has a time penalty compared to the airplane plus scenario. A trip by car is the least preferable, because of CO 2 emissions, travel safety and time. Direct costs of all three scenarios are comparable. Rail has the lowest emissions per passenger in the scenarios, hence it is important that network improvement programs continue and ticket prices stay in line with the price of travelling by car or airplane. An individual traveller was chosen for different reasons. One reason is that after understanding individual touristic travel decisions and their impact, it is a small step to estimate what is feasible if many more individuals would become ecofriendly touristic travellers. A second reason is that it allows an advice for governments and businesses to target individual tourists. Finally, there is the communicative impact of simplification on individual tourists.","CO2 emissions; fuel consumption; simulation; sustainability; Tourism","en","journal article","","","","","","","","","","","Transport and Planning","","",""

The building sector has a considerable role to play in doing so. The process of refurbishment is complex, since aspects such as design decisions, existing construction, energy efficiency, and user behaviour need to be considered. The motivation for refurbishing existing buildings is related to environmental, social, and economic aspects of their use or reuse, which are the three core aspects of sustainability. The key environmental motivation is to reduce energy consumption from fossil fuels and related greenhouse gases (GHG) emissions, and to include energy generation from renewables; the key economic motivation is to lessen the cost of energy used for heating, and the key social motivation is to reduce fuel poverty and improve the quality of life and wellbeing of the occupants.
This chapter aims to explain the role of refurbishment of the building stock for sustainability and resilience. Firstly, definitions of the levels of building upgrades are given, and the motivations for refurbishment are discussed. Furthermore, the ecological, economic, and social aspects of refurbishment are deliberated on, together with the importance of the building stock for resilience.

While uncertainty analysis has a long tradition, meeting sustainable development goals through long-term Life Cycle Engineering (LCE) decision making demands addressing Deep Uncertainty (DU). DU characterizes situations where there is no agreement on exact causal structures, let alone probabilities. In this case traditional, probability based approaches cannot produce reliable results, as there is a lack of information and experts are unlikely to agree upon probabilities. Due to the nature of LCE, this paper argues that methods to better cope with DU can make a significant contribution to the management of LCE. We introduce a set of methods that use computational experiments to analyze DU and have been successfully applied in other fields. We describe Robust Decision Making (RDM) as the most promising approach for addressing DU challenges in LCE. We then illustrate the difference between applying traditional risk management approaches and RDM through an example, complemented with the interview findings from a company using RDM. We conclude with a discussion on future research directions.","deep uncertainty; life cycle engineering; long-term planning; risk; sustainability","en","journal article","","","","","","","","","","","Policy Analysis","","",""

It was found that rainwater is cleaner than surface water, but still may contain contaminants. Especially the microbiological quality of rainwater is a point of concern, and therefore treatment, including disinfection, will be required. Furthermore, it was found that for densely populated areas, like a city district in Amsterdam, the quantity of rainwater that can be harvested from both built and paved surfaces equals only about half the amount that is required for the inhabitants. If rainwater is collected and treated at a neighborhood level, the costs are in the same order of magnitude as for centralized drinking water treatment.

Sustainable design should both, reduce the environmental impact caused by buildings throughout their life cycle and positively contribute to people’s well-being by addressing and being adaptable to their needs. There is the need for an early design support tool to aid implementing sustainability concepts since the project beginning toward sustainable built environment. Regardless of the existing number of building sustainability assessment tools, these were not developed to be applied at early design, requiring great data detail, inexistent at these stages. Most of the tools are directed to evaluate the performance of chosen solutions rather than aiding the decisionmaking process. This paper presents a new approach for an early design support tool for residential building. The tool is aimed to aid designers evaluate and compare different design alternatives, allowing them to make an informed decision based on the performance of the solutions, across the three cornerstones of sustainability. Additionally, the tool was thought to increase awareness across all stakeholders, promoting and encouraging the adoption of more efficient solutions. The structure of the tool and its main framework are depicted in this paper. To identify the criteria to include in the tool it was necessary to analyse the existing sustainability assessment standards and tools as well as the project teams’ actions. The level of detail of the indicators was also analysed as at early design not all aspects are relevant or capable of being addressed. This analysis led to the nineteen indicators, spread in seven categories. Using this tool, it is expected that buildings can easily be adapted to new necessities, extending their life cycle while improving life quality, and consequently reducing their environmental impact.","Early design stage; sustainability; buildings; flexible design","en","conference paper","","","","","","","","","","","","","",""

Ultimately, students are the ones using these sustainability marketing materials to assist in their decision at which institution they will pursue their studies. The sheer volume of interpretations of the word sustainability with regards to higher education institution leaves ample room for potentially misguided initiatives or marketing.
A universal system for assessing a higher educational institution’s sustainability has not been translated into a measurable reality. It is proposed that a universal system would help create a common understanding of sustainability within higher education institutions and would help in stakeholder understanding, institutional accountability and impactful application of sustainable initiatives.
This research looked to answer if a holistic framework could be created that would aid stakeholders in reviewing a university’s level of sustainability. And, if so, if this vision of a fully sustainable university could be translated into a measurable reality.
The research was approached in a structured way. Each chapter represents a published and peer-reviewed step towards addressing if a holistic framework could be created that would aid students in reviewing sustainability tools, assessments and marketing. The qualitative and quantitative conclusions from each chapter influenced the subsequent chapters, eventually leading to the creation and testing of two digital tools.

This leads us to conceptualize the notion of sustainability as a set of values, including safety, security, environmental benevolence, resource durability, and economic viability of the technology. The practical usefulness of sustainability as a moral framework is highlighted by demonstrating how it is applicable for understanding intergenerational dilemmas—between present and future generations, but also among different future generations—related to nuclear fuel cycles and radioactive waste management.","equity; fuel cycle; future generations; radioactive waste; safety; security; sustainability; OA-Fund TU Delft","en","journal article","","","","","","","","","","","Ethics & Philosophy of Technology","","",""

(TU Delft Spatial Planning and Strategy; Western Norway University of Applied Sciences)","","2017","The United Nations Paris agreement of 2015 highlighted the need for urban planning to prevent and contain urban sprawl so as to reduce trip lengths through an efficient distribution of agglomerations and a well-balanced urban pattern distribution, all while considering travel behavior and accessibility to green areas, services, and facilities on different temporal scales. For the Vienna-Bratislava metropolitan region, our integrated modeling approach uses a combination of multifractal spatial modeling along with a space syntax perspective. Multifractal strategies are intrinsically multiscalar and adhere to five planning principles: hierarchical (polycentric) urban development to manage urban sprawl; sustainable transit-oriented development; locally well-balanced urban pattern and functions distribution to enhance vital urban systems, local centers, and neighborhoods; penetration of green areas into built-up areas; and the preservation of large interconnected networks of green areas to conserve biodiversity. Adding space syntax modeling to a multifractal strategy integrates how space relates to functional patterns based on centrality, thus applying a socio-spatial perspective. In this paper, we used the following workflow for an integrated modeling approach: (1) Space syntax to identify the urban systems’ hierarchy and so determine a spatial strategy regionally; (2) Fractalopolis to create a multifractal development plan for potential urbanization; and (3) Space syntax to design a strategic urban master plan for locating new housing and facilities vis-à-vis socioeconomic factors.","Decision model; Space Syntax; Fractals; multiscale analysis; sustainability","en","journal article","","","","","","","","","","","Spatial Planning and Strategy","","",""

(TU Delft Design Aesthetics)","","2016","Even though designers are specifically trained to create and build new products, their contribution to innovation in the food industry is relatively small. The industry seems unfamiliar with the ways in which designers operate and may be unaware of the added value they may provide. Therefore, this article identifies the potential roles that designers could fulfil within large food companies. The development of new consumer products requires knowledge of target consumers, production technology and the business environment. These three types of expertise are often concentrated in different departments. Although highly experienced product experts such
as culinary chefs may be able to integrate this knowledge, involving designers may be a more fruitful strategy. First of all, designers tend to approach design challenges holistically, which broadens the scope of the project. As a consequence, designers will provide more innovative solutions, which can guide multiple project aspects simultaneously (production, packaging, marketing). Second, designers shape their own tools, which will engage the others involved. Third, designers are equipped to manage the product development process and can facilitate cooperation between the disciplinary
experts. Fourth, designers can play a role in bringing together and integrating the knowledge from the different disciplines. By strengthening these roles, large food companies can deliver innovations that address actual consumer needs, provide a positive contribution to society and consolidate long-term profitability and growth. For designers, foods represent interesting prototyping materials, which are firmly rooted in daily, cultural practices and can be enjoyed through all the senses. Their regional, seasonal and perishable character challenges designers to connect consumers with agriculture, trading and processing methods.","innovation; food industry; designer; chef; holistic approach; tools; facilitation; sustainability; OA-Fund TU Delft","en","journal article","","","","","","","","","","","Design Aesthetics","","",""

(TU Delft Urban Development Management)","","2016","In recent years Dutch real estate developers have been subject to some societal market trends that force them to change roles (Heurkens, 2013). The decreased demand for office space, limited debt funding, challenging user demands, stalling public investments, and increased competition from new companies, necessitate developer to deploy more new development, investment and partnership strategies. In this regard, investing in innovations, applying new business models, and adopting sustainability principles seem necessary for Dutch developers to remain a key player within urban real estate development. However, a Dutch study (Panteia, 2013) revealed that the real estate development industry is a conservative sector that ranks among the least innovative nation-wide. Recent studies focusing on the changing role of Dutch developers in relation to innovation, business models and sustainability show similar results. Haak & Heurkens (2015) indicate that Dutch developers are innovating in their operations, products and services, and business models, but these are not supported by changing corporate management strategies. Similarly, Bogers (2015) argues that business model changes likes new forms of collaboration, focus on cash flows, and market-driven development are occurring, but that it remains to be seen whether these changes are structural in times of an apparent real estate market boom. Additionally, Buskens (2015) concludes that sustainability is not treated as a key part of development strategies, which limits the Dutch developer’s ability to change roles and practices. Therefore, this paper advocates that insight is needed into the institutional conditions that assist Dutch real estate developers to adopt new development, investment and partnership roles and strategies.

It follows, if predicted climate changes are correct, we need to adapt existing stock sustainably. In city centres outside Australia there is a history of office to residential conversions. These types of conversions are few in number in Sydney although evidence suggests a trend is emerging in conversion adaptations. In 2014 102,000m2 of office space was earmarked for residential conversion in Sydney as demand for central residential property grows and low interest rates create good conditions. Linked to this, the CBD population is projected to increase by 4% to 2031 requiring 45000 new homes and, this increase coincides with a stock of ageing offices. A further factor is the Sydney office market is set to be flooded with the Barangaroo development office supply in 2017; thus conditions for residential conversion are better than ever. However; what is the level of sustainability in these projects? And, are stakeholders cognisant of the sustainability issues in these projects? Through a series of interviews with key stakeholders, this paper investigates the nature and extent of the phenomena in Sydney, as well as the political, economic, social, environmental and technological drivers and barriers to successful conversion. To date no major study exists on conversion adaptation in Sydney and most residential development is new build. There is substantial potential to change the nature of the CBD and enhance sustainability with the residential conversion adaptation of office space and this paper explores this potential. The findings show that opportunities are being overlooked to appreciate and acknowledge the sustainability of this type of adaptation and that there is a need for a rating tool to encourage greater levels of sustainability; and to acknowledge existing levels of sustainability achieved in these projects.","residential conversion adaptation; sustainability; Sydney","en","conference paper","ZEMCH Network","","","","","","","","Architecture and The Built Environment","Real Estate & Housing","","","",""

These problems have led to the development of legislative policies, regulations and targets to limit material and energy use in buildings. In order to achieve Energy Performance Building Directive's 2020 target towards energy neutral buildings, most regulations and policies focus on decreasing the operating energy, as a result of which this energy has reduced and is still reducing, thereby increasing the importance of embodied energy consumption in buildings. Most of the embodied energy and some of the operating energy of a building is related to the structure. Hence, one possibility is to minimize the energy consumption of a building by varying its structural design. Another possibility is to increase its service life. However, the relationship between adaptability and energy consumption is not always linear. Hence there exists the potential to apply computational methods to obtain a more optimal design from the point of view of energy efficiency and sustainable building design. This paper investigates the development and application of a computational tool that optimizes the conceptual stage design of a building to have minimum embodied energy and some aspects of operating energy, depending on the adaptability required. For this purpose, a parametric computational framework for sustainable building design was developed and implemented by the tool. The working prototype of the tool focuses on low-rise rectangular grid office buildings in steel and multi-objective optimization techniques. Test cases were applied and their results were validated. Finally, conclusions were drawn on both the framework and the tool, and its limitations and possible future developments are discussed.","embodied energy; sustainability; parametric design; computational tool; conceptual stage","en","conference paper","KIVI","","","","","","","","Civil Engineering and Geosciences","Structural Engineering","","","",""

(promotor); Dijkema, G.P.J. (promotor); Nikolic, I. (promotor)","2015","The Westland-Oostland Greenport is a large Dutch industrial cluster that is economically, socially and culturally important. Like many industries and regions, the greenport is facing serious challenges as a result of globalisation, energy supplies, and greenhouse gas emissions. These challenges can be understood as sustainability issues that come from an imbalance between the economic and social values that the greenport presently enjoys and the environmental values that it lacks. Greenports are complex adaptive systems, which means that the different challenges and values are all interconnected in complex and dynamic ways. This also means that improving the greenport is a matter of helping it evolve from its current state of imbalance toward a new state of sustainable balance that will help the greenport endure long into the future. The problems of unsustainability are growing increasingly urgent, which means the greenport can hardly afford to wait for a spontaneous change toward sustainability. Unfortunately, complex adaptive systems and state changes within those systems cannot be managed top-down. Thus, the Westland-Oostland Greenport wants to know `How can we manage a transition to sustainability?' In response, the greenport is interested in Transition Management (TM), an approach to scientific research and policy formation that proposes to steer complex adaptive systems toward sustainability through a blend of bottom-up and top-down measures. TM certainly looks promising, but it is not yet clear ``what is the scope or feasibility of managing transitions''. On behalf of the Westland-Oostland Greenport, this work uses TM to explore how a transition to sustainability might be managed within in the Westland-Oostland Greenport. At the same time, this work also reflects on TM itself by questioning whether sustainable transitions can be managed at all. The Research Questions There are two main research questions, each with two sub-questions. The first main research question is ``Can TM help the Westland-Oostland Greenport manage a transition to sustainability?'' which can be broken down into the following sub-questions: What new understanding and insight can be gained from applying TM to the Westland-Oostland Greenport? What influence, policy recommendations and practical advice can be derived from the new understanding and insights gained by applying TM approach to the Westland-Oostland Greenport? The second main research question is ``How can TM be improved as a consequence of being applied in the Westland-Oostland Greenport?'' which has the following sub-questions: What potentially problematic assumptions can be seen within the TM approach as it was applied to the Westland-Oostland Greenport? What insights, further questions, or improvements for TM come from exploring these problematic assumptions? The Research Methods The research begins with a literature review to explore the most important ideas of complex adaptive systems, sustainability and TM. The first main research question is then addressed by applying several research methods to the Westland-Oostland Greenport, all of which are consistent with TM. These research methods include a case study, a participatory workshop, and an agent-based model. Next, the second main research question is addressed through a series of relatively abstract agent-based models and modelling experiments. Each model is designed to test an assumption within TM about how complex adaptive systems work or about how transitions can be managed. Results Part I covers the application of various research methods to the Westland-Oostland Greenport. Each of these produces a set of new insights into the greenport and its sustainability problems. On the whole, the insights tend to relate to specifics, such as the identification of specific drivers behind a diffusion of interest, specific gaps in local sustainability policies, and specific stakeholder features that influence relevant behaviour. Many of these insights are turned into practical recommendations that policy-makers could use to help manage a transition to sustainability within the greenport. For example, recognising the specific drivers behind a particularly rapid and important technology diffusion can help policy-makers drive desirable diffusions in the future. Similarly, identifying gaps in current sustainability policies allows policy-makers to develop more effective programmes without duplicating existing programmes. Not all of the insights are easily converted to direct policy recommendations; some are better understood as advice on the process and typical problems associated with policy formation. For example, recognising that innovators are quick to embrace change is usually seen as a good thing when policy-makers want to encourage a desirable change, but quickly becomes problematic after a desired change has been effected and further change is seen as less desirable changes. Some specific insights could not have been predicted, but none were inconsistent with general TM expectations. For example, energy market liberalisation proved to be one of the most important drivers of the combined heat and power technology diffusion, even though the technology diffusion was not an intended or expected consequence of long term national energy market policies. TM expects transitions and diffusions to occur when `windows of opportunity' are opened. Thus, even though this particular diffusion was not an intended result of its most important driver, neither was it an especially surprising outcome. In this way, the policy recommendations based on the insights uncovered in Part I are all consistent with the theory of TM and with past TM policy recommendations. Part II covers the agent-based models that investigate various potentially problematic assumptions within TM. Each of these models produces new insights, some of which can be related to the Westland-Oostland Greenport but most of which relate to TM itself. None of the assumptions held up particularly well to investigation. As a result, and unlike the relatively cut-and-dried insights in Part I, the insights in Part II are best understood as calls for more critical analysis of TM, creative reinterpretation of past observations, and innovative approaches to understanding complex adaptive systems and sustainability. For example, the first of four agent-based models tested the commonly relied upon TM assumption that a large and diverse committee can produce a more objective system description that can a single individual. The results of that model suggested that all system definitions are mutually exclusive of all others, regardless of how they were produced, suggesting that no system description is obviously more objective than any other. Another agent-based model examined the pervasive TM assumption that innovation and selection are opposing forces but found no evidence to support the proposed innovation-selection relationship nor the many TM programmes that rely on the assumed relationship. Importantly, these insight do not claim to offer a definitive answer or superior explanation to replace the TM assumptions examined by the models. For example, the conclusion that diverse committees do not produce more objective system definitions but does not entail any proposal for an alternative process or structure that produces more objective system definitions. Likewise, refuting the assumed relationship between innovation and selection is not the same as proving that innovation and selection have some other relationship instead, although an alternative view of innovation and selection is offered as a possibility for further investigation. As a consequence of the different research questions and approaches used, the policy recommendations and insights from Part II are less practical and specific than those from Part I. For example, policy-makers are not advised to avoid large and diverse committees when creating system descriptions, but are urged to focus on the actual benefits of wider public engagement rather than unsubstantiated assumptions about objectivity. Also unlike Part I, some of the insight and recommendations of Part II are aimed at users or proponents of TM rather than directly at policy-makers. For example, many TM practices rely on using (more) objective system descriptions. By undermining the assumed objectivity of system descriptions, the experimental results call the validity of all of these practices into question. When the results of all four of the various agent based modelling experiments are taken together, serious inconsistencies become visible within TM, some of its assumptions begin to appear very flawed, and the whole field looks as if it would benefit from some deep and critical self-reflection. Conclusions Overall, the works finds that applying TM research methods to a complex adaptive system generates new insights about the specific details of that systems, much of which can be used to create practical recommendations or justify policies in relation to sustainability efforts. The new insights and details revealed by the research may be surprising in their uniqueness or specificity, showing that TM research can be extremely valuable. Despite their potentially surprising uniqueness or specificity, TM research methods are unlikely to produce any results, insights or policy guidance that are truly unexpected or that are inconsistent with established TM theory or existing policy proposals. At the same time, it is important to note that TM has not yet managed a transition to sustainability. Perhaps TM merely needs more time to achieve the desired outcome, but it is also possible that more and more of the same TM efforts will only produce more and more of the same lack of success. The work also finds that TM, as it currently stands, contains some incoherent ideas and relies on some unsupported assumptions. These inconsistencies and assumptions may be hindering TM efforts to achieve sustainability, so TM is encouraged to critically reflect on its ideas about complex adaptive systems, transitions and sustainability as well as its own processes, research methods and sustainability efforts. In so doing, TM may correct some problems, discover new and better ways to work, and become a more effective tool for managing systems and moving them toward sustainability. This critical self-analysis may also reveal that TM is fundamentally flawed and should be discarded, but that too could inspiring researchers to devise entirely new approaches that are more successful in achieving sustainability.","greenhouse horticulture; sustainability; complex adaptive systems; agent-based modelling; transition management","en","doctoral thesis","","","","","","","","","Technology, Policy and Management","Infrastructure Systems & Services","","","","52, 4"

This seems also the case with sustainable building projects. It is therefore necessary that project managers are trained to deal with these problems, especially by learning from their performance. In this article we motivate why and propose how. Based on literature study we elaborate on the concepts of reflection-in-action, design-thinking and managing as designing. In sustainable building projects the problem occurs on a regular basis that the often big ambitions in the initiative phase are not realised in the realisation phase. These ambitions perish because of a lack of substantial knowledge regarding the quality-, time- and cost-aspects of sustainable building projects. More important than this sufficient substantial knowledge is an integral approach of the entire building process. Exactly this integral approach of the process with its characteristic of working from sketch to detail –and backwards- appears to be very suitable for sustainable building projects and requires a management approach that allow, support and stimulates this; an approach that can be characterised as designing project management. Where the concepts of reflection-in-action, design-thinking and managing as designing are interrelated in the concept of learning we introduce the project management design cycle. Project managers do not only need to use this searching and experimenting approach with awareness in order to learn from their performance, but students in project management will also have to be trained in how they can learn from their performance as a project manager. We propose that training related to cases e.g. as in management games seems to be the most suitable.","sustainability; training; reflection-in-action; design-thinking; project management","en","conference paper","IBEA Publications Ltd.","","","","","","","","Architecture and The Built Environment","Management in the Built Environment","","","",""

In order to improve long-term sustainability in all aspects: equitable water and sanitation access, public health risks and environmental impact and operational costs, water and sewage systems with household connections are being implemented. In this shift from emergency to sustainable phase, urban infrastructure selection and design methods were found to be beneficial and adapted for the situation. Aspects such as stakeholder management and project management, throughout design and implementation phases, are vital and similar to the planning processes of urban water utilities. Potential for further sustainability lies in the development of operation and maintenance and administrative strategy to reflect and maximise the significant investment. Therefore, a shift is necessary from a humanitarian approach toward a more structured vision based on master planning. Quality control of the entire process and outputs requires a project management unit. The long term master planning perspective of urban development and urban utility perspective of operational sustainability is determined to be essential in the conception of water and sanitation schemes in Zaatari refugee cam","cost effectiveness; drinking water; infrastructure; public health; refugee camp; sanitation; sustainability; wastewater","en","conference paper","IWA","","","","","","","","Civil Engineering and Geosciences","Water Management","","","",""

Combining personal and environmental benefits, called double benefit theory, is promoted as an effective green marketing strategy but so far not supported by quantitative research as being effective to reach mainstream consumers. We studied the effect of advertisement elements (layout color, benefit type, and heritage) on the products’ perceived sustainability, quality and fashion image, and buying intentions of mainstream consumers. Two hundred adults participated in a study that was based on a 2 (red vs. green layout) × 2 (personal vs. environmental benefit) × 2 (local vs. global heritage) between-subjects factorial design of a sustainable shoe advertisement. The impact of these independent variables on product image as well as on buying intention was analyzed by means of three-way ANOVAs. In line with the double benefit theory, combining a personal benefit with a green layout led to the highest buying intention. Moreover, a mediation analysis revealed the effect of emphasizing a personal benefit on buying intention was mediated by fashion image but not by sustainability.

Communication about sustainability can be explicit (in words or labels) or implicit (through materials, images and/or colours). The implicit form could be described as sustainable aesthetics. The explicit form can be presented either as factual information or in the form of stories. People engage more with stories than with factual information, as it allows for easier connections with previous experiences. Hence, storytelling makes for a compelling marketing tactic. Instead of telling a story yourself as a brand, enabling and encouraging your consumers to tell your story to their peers offers strong marketing potential as well.

(promotor)","2014","A major challenge in striving for a more sustainable society is the selection of technological systems. Given the capital intensity of industrial production plants, power generation systems and infrastructure, investment decisions create path dependencies for decades to come. It is difficult to know which technological system is preferable when considering the multiple objective of environmental, economic and social sustainability. E.g., a system that is preferred from the environmental point of view is not necessarily the system that is preferred from the economic and/or social point of view. Furthermore, the results of the assessments change over time because of new insights into environmental, economic and social sustainability and because they are prone to changing needs, economic conditions and societal preferences. Because of these uncertainties, it is hard to decide which technological system or systems should be chosen, e.g. to meet national and international targets with regard to climate change. Another way of assessing technological systems is the use of exergy analysis, a thermodynamic assessment method. Exergy analysis makes visible where work potential is lost. This work potential is needed for all the things we would like to do, i.e. nothing happens without the consumption of some work potential. Work potential that is lost, is lost forever. The only way to replenish the amount of work potential available on earth is by capturing new work potential from solar and/or tidal energy. Researchers active in the field of exergy and sustainability claim that the loss of work potential, also known as exergy loss, and sustainability are related. However, the loss of work potential is no part of the regular sustainability assessment methods. The objective of this research is to provide insight into the value of exergy analysis in sustainability assessment of technological systems. A literature research into the relationship between exergy and sustainability resulted in a theoretically founded relationship between exergy losses and the environmental impact of technological systems. A problem with investigating the relationship between exergy and sustainability is that there is no single measure of sustainability. Combining the results of the environmental, economic and social sustainability assessments into one sustainability indicator leads to a loss of information and necessitates the use of weighting factors. Another difficulty is that a commonly accepted operationalization of the term 'sustainability' does not exist. Accordingly, a list of requirements to methods for sustainability assessment of technological systems has been drawn up. All assessment methods cover the operational phase of installations, equipment and infrastructure including the amounts of inputs and outputs. Not all methods take into account the phases of construction and decommissioning of the installations, equipment and infrastructure and the following components of sustainability: the depletion and/or scarcity of the inputs, the distinction between renewable and non-renewable inputs, the disposal and/or abatement of emissions and waste flows, land use, exergy losses, economic aspects and social aspects. In addition, methods for the calculation of sustainability indicators should be objective and sufficient data should be available to calculate these indicators. The sustainability assessment methods found in the literature appear to be incomplete with respect to the list of requirements. The environmental life cycle assessment methods are not fully objective because they make use of weighting factors and because no consensus exists about all models used for quantifying environmental impact. The economic methods do not include all indirect costs and their indicators change over time because of market developments. The social methods suffer from the limited availability and qualitative or semi-quantitative nature of many data. The exergy analysis methods found in literature do not consider all components of sustainability and/or make use of indicators, equations and weighting factors that are not commonly accepted. It was therefore decided to develop a new exergy analysis method on the basis of fundamental scientific equations. The newly developed exergy analysis method has been named the Total Cumulative Exergy Loss (TCExL) method and takes into account as many of the designated components of sustainability as possible. The TCExL is the summation of the exergy loss caused within the technological system including its supply chains, the exergy loss caused by abatement of the resulting emissions and the exergy loss related to the land occupied by the technological system including its supply chains. The latter is relevant because land use prevents capturing new exergy from sunlight by the ecosystem. Components of the list of requirements that can only indirectly be considered when calculating the exergy loss caused by a technological system are the depletion and scarcity of resources as well as the economic and social aspects of sustainability. The TCExL method is an improvement compared to existing exergy analysis methods in the sense that it is solely based on the calculation of exergy losses and that it takes into account all exergy losses caused by a technological system during its life cycle. However, until now the abatement exergy loss of only a few emissions is included because of the lack of data regarding other emissions. The value of exergy analysis in sustainability assessment of technological systems has been investigated by conducting two case studies that comprise several power generation systems and subsequently comparing the results of the assessment methods with and without exergy of the systems of each case study. Power generation was chosen as the subject of the case studies because of the major role of electricity in our society. The choice of the systems of the case studies is not meant to indicate that these systems are preferable and/or desirable compared to other central or decentral power generation systems, nor that it is not important to look at the transport, distribution, use and/or storage of electricity. The first case study consists of the following systems for coal-fired power generation in combination with LNG evaporation: a power plant of which the waste heat is used for LNG evaporation, an oxyfuel power plant that is combined with air separation and LNG evaporation, and a stand-alone power plant plus the combination of LNG evaporation with an Organic Rankine Cycle (ORC). The other case study concerns power generation from fossil and renewable sources and compares the co-firing of coal and wood pellets with a wind farm and with power generation from the combustion of bioethanol that originates from the fermentation of verge grass. The method applied for determining the environmental sustainability is the ISO-certified environmental Life Cycle Assessment (LCA) method with ReCiPe endpoint indicators as the result. The present worth ratio (PWR) has been calculated to determine the economic sustainability. A newly developed method based on man-hours and the Inequality-adjusted Human Development Index (IHDI) reported by the UNDP has been used to assess the social sustainability, because a standard method for social LCA is still under development and because it would be too time-consuming and costly to gather site-specific social data. From the case studies, it is concluded that the sustainability of our society can be improved by applying exergy analysis in the assessment of technological systems, but that in the case of comparing technological systems with different inputs, a technological system that is preferred from an exergetic point of view is not always preferred from the economic and social points of view. If according to the results of the TCExL method a system is preferred that has a lower economic sustainability, it must be realised that economic indicators do not include all indirect costs and change over time. In the case of comparing technological systems with different inputs or with inputs from different locations, the calculation of a social sustainability indicator like the IHDI_overall indicator introduced in this research can have an added value compared to calculating only the TCExL. From a sustainability point of view, it is important to use exergy wisely. The higher the amount of exergy that is available on earth, the better people will be able to meet their needs. Therefore, the TCExL can be used as a fundamental indicator in the operationalization of the definition of sustainable development by the Brundtland commission. It is also concluded that exergy analysis leads to more fundamental insights into which process or part of a system has the largest potential for improvement than the standard sustainability assessment methods. It is recommended that exergy losses be taken into account when striving for a more sustainable society and that the TCExL method be used in decisions between technological systems. Furthermore, it is recommended that a working group be set up to investigate the possibilities for increasing the use of exergy analysis and that the TCExL method be implemented in software tools.","exergy; sustainability; assessment; technological systems; life cycle; TCExL; power generation; energy policy","en","doctoral thesis","","","","","","","","","Technology, Policy and Management","Engineering Systems and Services","","","",""

However, the contribution to the national move towards sus-tainability is, according to the transition theory as well, still too small. It is therefore necessary to make the conditions more favourable for residents’ initiatives of this type. In the context of this urgent need, research was carried out into cohesion in residents’ groups, the required conditions and the attitudes of professionals. A qualitative approach to the research was chosen in order to clarify the underlying reasons and motivation of the parties involved. Three obstructing dilemmas and three perspectives for development were found. The limited motivation on the part of residents to take part in sustainability initiatives, either individually or as part of a group, and the fact that professionals have their own agenda, are an obstacle to sustainable development. On the other hand, ‘pull’ factors and ‘leaders’ – including impassioned professionals – and social cohesion among residents facilitate the transition to sustainability in a positive way. The ‘There & Later’ approach of professionals and the ‘Here & Now’ approach of residents can, however, be aligned at city-district level. This is possible if themes that do not relate to sustainability (e.g. the secure feeling of ‘knowing each other’) and the liveability of a residential area are incorporated in sustainability activities. In this way the use of renewable energy in residential areas in the Netherlands can be taken to a higher level.","housing; sustainability; urbanims; citizinsinitiative; renewable energy; CPO; residentsinitiative","nl","doctoral thesis","TUDelft faculty of Architecture and The Built Environment, A+BE","","","","","","","2014-09-26","Architecture and The Built Environment","Urbanism","","","",""

But sustainability is complex and not one thing, it relates to different sectors and multiple systems, and also to different zones, scales, ‘levels’ those systems occupy.

Situation, in a relational sense, matters. Without understanding this contextual, relational and framing factor we can end with inadequate or misleading answers to important questions. Questions need to be framed and framing involves complex topologies of spatial insides and outsides and functional parts and wholes. This relational and framing aspect of sustainability has been radically underconsidered and this paper will propose a method to address this deficit. The approach is ‘materialist’ but also ‘constructivist’, not in the sense of ‘social construction’. Instead it is proposed we live in a reality historically and technically constructed and that the ‘social’, the ‘economic’, the ‘cultural’ and even the ‘environmental’ are what we thus construct. This converges with a so-called ‘technoscience’ perspective, one that has been addressed through ‘actor-network theory’.

Key transition authors are predominantly Dutch. They repeatedly write together and cite each other's work. The transition literature is tightly knit with high degrees of internal references and a clearly distinguishable core. Transformation literature has fewer connections between authors and articles. The connecting articles, each with many global citations, form its basis. This analysis can be used as a step to continue the debate on the role of transition and transformation literature in sustainability and renewable energy policy.

From sustainability point of view, therefore, it is important to search for materials which can be used to reduce or to replace Portland cement in concrete. Among the mineral admixtures micronized sand with high purity SiO2 has been selected as cement replacement. Micronized sand is produced by grinding of quartz sand, which is the most abundant mineral in the earth’s crust. Therefore, the use of this material will not cause a depletion of resources. The objective of this research is to investigate the possibility of using micronized sand to partially replacement cement in concrete. The performance of cement-based material with micronized sand as partial replacement of cement was evaluated with respect to the microstructure, durability and sustainability both experimentally and by numerical simulations.","cement-based material; micronized sand; microstructure; transport properties; service life; sustainability; CO2 footprint","en","doctoral thesis","VSSD Science and Technology","","","","","","","","Civil Engineering and Geosciences","Structural Engineering","","","",""

This gap is caused by separated responsibility for the financing of the accommodation for the primary and secondary schools. Municipalities finance the initial costs of construction of these schools and school boards are responsible for the operating costs of the school building. According to architecture-based research on this subject (In 't Veld, Hamdan, & Barendregt, 2010) this split-up results in higher costs during the lifetime. This problem is often referred to as the split-incentive problem. The purpose of this article is to add case based evidence in order to support the idea that an integral approach captured in life cycle costs (LCC) will lead to more in-depth argued adjustments of school buildings. The research conducted nine case studies of secondary school buildings, which are newly build between 2005 and 2008. The schools were examined in terms of buildings characteristics, building costs and operations costs. With the aid of the Dutch sustainability measurement tool GPR-Gebouw1 the sustainability score of the schools is determined. For the construction sector in the Netherlands it can be concluded that it is generally acknowledged that sustainability is more expensive, however, studies indicate this is not unequivocally. An elaborated research of Davis Langdon reveals within a given spread of building costs an equal spread of certified buildings (Morris & Matthiessen, 2007). Our study supports this finding and found at least no clear relationship that sustainable schools have higher investment costs. The study shows a positive effect of sustainable measurements on the life cycle costs of secondary schools. There is an on-going discussion on ratios between initial costs and operating costs. Evans (1998) stated that there is a ratio of 1:5:200 between the construction costs, operating expenses and corporate operating costs. This ratio has already been further defined and reduced by Hughes (2004) and Ive (2007). The scenario analysis of our study shows that the operating costs still have a larger share in the life cycle costs than the investment costs. The difference between the investment and operating according to this study is by far not as impressive as stated by Evans, but still worthwhile to keep focus on LCC in policies for school development.","life cycle costs; school buildings; sustainability","en","conference paper","","","","","","","","","Architecture and The Built Environment","Real Estate and Housing","","","",""

Everything in the universe changes, evolution implies that the creation is not complete hence the possibility of evolving’ (Osho, 1985). Our society and economy are constantly changing. Hence the demands and wishes of users changes all the time. As now in China, the Netherlands had a quantitative demand in housing after the Second World War with a lot of booming developments. At the moment we face the consequences of these booming developments. The housing supply doesn’t match anymore the changed demand. So if we could do it all over again, we should answer this quantitative demand with a qualitative supply, namely real estate, which carries the capacity to adapt to these constantly changing demands. Such ‘evolving’ buildings should be designed to learn hence being able to adapt to changing conditions, integrate development with growth and evolve to survive like organisms do in a mature ecosystem (Biomimicry Life’s principles circle, 2010). In this way we don’t focus on maximization (most sustainable real estate at deliverance) but on optimization (flexibility offers the capacity to adapt to changes hence becoming more environmental-and userfocused through time). This paper does focus on patterns from nature (for instance evolve to survive) and their possible value in developing real estate. Analysis using TRIZ (a problem-solving, analysis and forecasting tool derived from the study of patterns of invention in the global patent literature) shows that there is only 12% similarity between biology and technology in the principles, which solutions to problems illustrate, while technology solves problems largely by manipulating usage of energy, biology uses information and structure, two factors largely ignored by technology (Vincent, 2006 - Biomimetics: its practice and theory). Biomimicry is learning from nature as a model, mentor, and measure and then emulating natural forms, processes, and ecosystems to create more sustainable designs (Benyus, 2002 Biomimicry). The core idea is that nature has already solved many of the problems we are dealing with: energy, food production, adaptability, climate control, benign chemistry, transportation, collaboration and more.","biomimicry; sustainability; flexibility; housing; revitalization; patterns from nature","en","conference paper","","","","","","","","","Architecture and The Built Environment","Real Estate and Housing","","","",""

In this paper we investigate the role of flexibility in sustainable port development in order to promote its incorporation in port projects. We establish that the greatest payoffs from flexibility are achieved through initiating new life cycle for a capital intensive port infrastructure, though reuse of the elements and materials also contributes to flexibility. Reuse concurrently optimizes use of natural resources, limits waste and pollution in the environment, conserves energy, and thus limits the overall negative ecological impact. It also results in significantly lowers lifecycle costs. Thus flexibility helps achieve (long-term) financial viability in face of economic uncertainty, while reducing environmental and social impacts. Therefore, flexibility considerations are important during design, procurement, and contracting of engineering projects. The best way to redirect the choice of decision-makers towards flexibility is to make visible its long-term benefits, and its contribution to sustainability.

This global challenge can often best be addressed at the local level, e.g. in cities by optimizing the role of civil society. Although there are approaches for assessing the sustainability of countries and cities, there is no dedicated framework for the assessment of the sustainability of urban water management. We have therefore compiled a comprehensive list of indicators (the city blueprint) for this. The city blueprint is proposed as a first step towards gaining a better understanding and addressing the challenges of integrated urban water management (IUWM). City blueprints will enable the IUWM of cities to be compared, and stimulate the exchange of success stories (good practices) between cities to address the enormous IUWM challenges which lie ahead. The city blueprint provides a quick scan and baseline assessment. It comprises elements from a variety of methodologies, such as water footprint, urban metabolism and ecosystem services. The indicators have been subdivided into eight broad categories, i.e. (1) water security following the water footprint approach developed by Hoekstra and Chapagain (2007), (2) water quality, which includes surface water and groundwater, (3) drinking water, (4) sanitation, (5) infrastructure, (6) climate robustness, (7) biodiversity and attractiveness and (8) governance. Experience using city blueprints for the cities of Rotterdam, Maastricht and Venlo (in the Netherlands) have been included as practical examples. It was concluded that simplicity (ease of calculation and data availability), transparency and ease of communication makes the blueprint a valuable tool for policy makers, decision makers and resource managers as a first step in the process of understanding, envisioning, developing and implementing measures to transform the water management of cities. The best results are obtained when all the stakeholders are involved and connected right from the start.","sustainability; water management; climate change; urban metabolism; water footprint; city blueprint","en","journal article","Springer-Verlag","","","","","","","","Civil Engineering and Geosciences","Water Management","","","",""

Engineers devote considerable resources to assure their products will not fail and considerable progress has been made in the development of tools and methods for understanding and avoiding failure. Engineering ethics, on the other hand, is concerned with the moral and social aspects related to the causes and consequences of technological failures. But what is meant by failure, and what does it mean that a failure has occurred? The subject of this paper is how engineers use and define this notion. Although a traditional definition of failure can be identified that is shared by a large part of the engineering community, the literature shows that engineers are willing to consider as failures also events and circumstance that are at odds with this traditional definition. These cases violate one or more of three assumptions made by the traditional approach to failure. An alternative approach, inspired by the notion of product life cycle, is proposed which dispenses with these assumptions. Besides being able to address the traditional cases of failure, it can deal successfully with the problematic cases. The adoption of a life cycle perspective allows the introduction of a clearer notion of failure and allows a classification of failure phenomena that takes into account the roles of stakeholders involved in the various stages of a product life cycle.","failure; life cycle; failure analysis; product development; failure trajectory; sustainability","en","journal article","Springer","","","","","","","","Technology, Policy and Management","Values and Technology","","","",""

Therefore, a railway station’s location in a built environment and its degree of accessibility is essential to reach as many travellers as possible. Even though there exist several writings on network cities and TOD principles concerning rail accessibility to urban centres and sub?sentres, the spatial configuration of the local street and road network in a railway station’s vicinity is seldom taken into consideration in the discussion on railway transport. Therefore, two different analyses methods were used with purpose to identify the degree of regional and local inter?accessibility of all train stations in the province of North Holland in the Netherlands. The space syntax method provided measurements on a street net’s interaccessibility on different scale levels, while the Node Place model analyses provided the degree of a station’s attractiveness in terms of place value and means of transportation value. As the results show, correlations were found between a station’s degree of local and regional accessibility and frequency of the timetables. When implementing and improving sustainable means of public transportation, urban functions such as dwellings, shops, services, workshops and offices have to be in short walking distances from stations and the street network must be easily understandable for way?finding. The results from this inquiry were applied in the province’s policy plan as a priority list for station improvements in terms of degree of local accessibility. Moreover, the priority list of the implementation of new housing areas was made on basis on the degree of local and regional accessibility to existing railway stations.","railway station; accessibility; node place value model; sustainability","en","conference paper","PUC","","","","","","","","Architecture and The Built Environment","Urbanism","","","",""

Power TAC is a competitive simulation that models a “liberalized” retail electrical energy market, where competing business entities or “brokers” offer energy services to customers through tariff contracts, and must then serve those customers by trading in a wholesale market. Brokers are challenged to maximize their profits by buying and selling energy in the wholesale and retail markets, subject to fixed costs and constraints. Costs include fees for publication and withdrawal of tariffs, and distribution fees for transporting energy to their contracted customers. Costs are also incurred whenever there is an imbalance between a broker’s total contracted energy supply and demand within a given timeslot. The simulation environment models a wholesale market, a regulated distribution utility, and a population of energy customers, situated in a real location on Earth during a specific period for which weather data is available. The wholesale market is a relatively simple call market, similar to many existing wholesale electric power markets, such as Nord Pool in Scandinavia or FERC markets in North America, but unlike the FERC markets we are modelling a single region, and therefore we do not model location-marginal pricing. Customer models include households and a variety of commercial and industrial entities, many of which have production capacity (such as solar panels or wind turbines) as well as electric vehicles. All have “real-time” metering to support allocation of their hourly supply and demand to their subscribed brokers, and all are approximate utility maximizers with respect to tariff selection, although the factors making up their utility functions may include aversion to change and complexity that can retard uptake of marginally better tariff offers. The distribution utility models the regulated natural monopoly that owns the regional distribution network, and is responsible for maintenance of its infrastructure and for real-time balancing of supply and demand. The balancing process is a market-based mechanism that uses economic incentives to encourage brokers to achieve balance within their portfolios of tariff subscribers and wholesale market positions, in the face of stochastic customer behaviors and weather-dependent renewable energy sources. The broker with the highest bank balance at the end of the simulation wins.","autonomous agents; electronic commerce; energy; preferences; portfolio management; power; policy guidance; sustainability; trading agent competition","en","report","Erasmus Research Institute of Management (ERIM)","","","","","","","","Electrical Engineering, Mathematics and Computer Science","Software Computer Technology","","","",""

For large parts of Western Europe and the US the latter will be, according to economic principles of concentration and revaluation of city life, the main focus in development. Like the rest of the world, the growth of cities seems irreversible and a continuous fight against sprawl. Other studies reveal that sustainable economics require focus and insight on building characteristics. So density is the focal point. Urban quality can be partly quantified in parameters like Floor Space Index (FSI - intensity), Ground Space Index (GSI - compactness), Open Space Ratio (OSR - pressure on open space) and height. The density and the morphology of the urban fabric can be adequately described by these parameters, using plot charts where the different parameters are placed on the axis and the elements are plotted and analysed. The value of real estate property is determined by the building value and the land value. The building value is related to the location due to rent levels enabling building quality, urban quality and contextual (functional and economical quality). The land value should be almost equivalent to location value and, at least at the start of the process, is calculated using the looked-for Floor Space Index. It is expected that performance of real estate objects, categorised in different sets, defined by these urban parameters will show similar grouping, by which the density related behaviour can be forecasted. Used as a tool to analyse a portfolio it will give insight in the relation of this stock and density. This tool and gained insight is especially needed for emphasising externalities of density to a project scope. The central question “Why Tall?” can be answered by these regional advantages. At the same time urban planners, at least in Rotterdam, require tall buildings iconic by slenderness, an effect further stressed by regulation. This city is exemplary for a situation in which it is already hard to distinguish a need for going high. All externalities have to be taken into account. Even beyond economic viability, the fineness creates a setback on the performance by density. The original density plot charts are twodimensional. By adding colour the performance is shown and by using marker styles the impact of building volume related to the financial indicators can be clarified.","sustainability; urban quality; density; intensity; compactness","en","conference paper","Korean Council on Tall Buildings and Urban Habitat (CTBUH Korea)","","","","","","","","Architecture","Real Estate and Housing","","","",""

With around half of all greenhouse gas emissions attributed to the built environment; it has a significant role to play in mitigating global warming. With large percentages of office stock structurally vacant in some city centres and only 1 or 2% of new buildings added to the total stock each year; the scope for reductions lay with adaptation of existing buildings. The stock with the highest levels of vacancy and obsolescence offers the highest potential of all. Many cities are now aiming to become carbon neutral. Successful retrofit demands that social, technological, environmental, economic and legislative criteria are addressed. Buildings have to meet user and community needs. City centres comprise a range of different type of office stock with regards to age, size, location, height, tenure and quality. All buildings present challenges and opportunities with regards to retrofit and sustainability and integrating retrofit measures that reduce energy, water and resource consumption. Using a selection of low grade office buildings to develop retrofit profiles, this paper addresses the questions; (a) what is the nature of retrofits in relation to low quality office building stock in the Central Business District (CBD) and, (b) what is the extent and scope for sustainable retrofits to low quality office buildings. Using Melbourne CBD retrofit events of low quality office buildings were analysed between 1998 and 2008 to identify the scope and extent for integrating sustainability into retrofits projects.","office buildings; sustainability; refurbishment; building adaption; Australia","en","conference paper","","","","","","","","","","","","","",""

Based on the results it was concluded that it is not necessary to have a pre-defined (sustainability) ambition in order to realize a project that can be considered sustainable in practice. Most of the respondents indicated that the ambition developed throughout the project, mainly because of the potential sustainable reputation or the parties involved in the project. Ambitions were not set as highly as expected: about half of the respondents consider preservation of the building and recycling as sustainable solutions already. The composition, management and collaboration of the construction team were found to be very important during the process.

Nowadays, it is generally assumed (and accepted) that urban density is related to sustainability. New urban planning approaches, loosely based around new urbanism, are successfully reducing environmental impacts by altering the built environment to create and preserve sustainable cities which support sustainable transport.

In design-build contracting businesses, such drivers include the re-engineering of value chains with all tiers of designers, subcontractors, and suppliers. In design businesses, such drivers include the transformations of design firms into long viewers, path dependency breakers, stock-specific programmers, object-specific planners, impact blockers, and impact cause tracers.

This debate has had renewed significance given the emergence of the sustainability agenda and the need to extract additional value from built assets through life. Developing a better understanding of how buildings change over time is arguably crucial to informing architects concerned with extending the life of buildings. This paper critically reviews literature on adaptability, together with that relating to knowledge feedback and architectural practice, in order to construct a theoretical platform for understanding how knowledge of how buildings change can be used to inform design decisions. A pilot case study is used to illustrate the ways in which buildings change could be captured to inform adaptable designs in the future. The work reveals a lack of knowledge in how buildings change and how, if this was fed back to architects, it could support design decisions that might increase the life of many buildings.","building appropriation; adaptibility; design decisions; feedback; sustainability","en","conference paper","","","","","","","","","","","","","",""

The construction industry is a key contributor to the greenhouse emissions and future legislative adjustments for the built environment are well underway. The industry will face many challenges and it is expected that its profile will be very different by 2050. The scenario that there will be pressure for the supply of labour, materials and components to be much more localised due to increased energy costs is very likely. In turn, supply chains, which currently are becoming increasingly long as the demands of projects become increasingly complex, will inevitably have to face the localisation challenge. The long supply chains provide the increasingly high levels of technical input relating to design, manufacture, installation and servicing in the context of an industry anxious to maintain flexibility in the face of uncertain levels of workload and investment. These tall contractual hierarchies contain a massive amount of expertise but the contractual hierarchy constrains the effective management of knowledge and innovation through excessively long network paths, containing multiple, perversely incentivised, network bridges and gate keepers. Contractual relationships, knowledge management and information exchange networks define the localised supply chains and important work needs to be done to examine the potential for these networks to be established and be maintained. Social network analysis can be employed to map existing supply chains and to provide predictive models for local supply chains in 2050. The paper discusses how to best examine what the capabilities of the local supply chains today are and what their capabilities would be if they were specifically enhanced to meet 2050 challenges. These capabilities inform supply chain management targets which mainly focus on continuous improvements of the supply chain increasing value and stimulating knowledge sharing and innovation. Sustainability targets are yet to be fully incorporated in the value equation, which is what the 2050 challenge requires; therefore particular attention is paid to it. It is suggested that exploring the location of intellectual capital in construction supply chains, demonstrating how the use of BIMs and vertical integration of the supply chain might be exploited to provide interfaces between local supply chain actors and end-users, examining the logistics and embedded energy, comparing the todays logistical demands with a 2050 localised supply chain scenario, is a starting point in developing the concept of the localised supply chain as a successful approach to the sustainability problem.","sustainability; localisation; supply chain; knowledge management; information exchange networks","en","conference paper","","","","","","","","","","","","","",""

Design is characterized by its projective and ambivalent nature, and therefore a conscious effort to anticipate the outcomes of design intentions is crucial. Consequently, all design is inherently laden with uncertainty, doubt, and specifically in some technology-driven design projects - contradictions and controversies. Typically, such uncertainties and contradictions are not considered during the initial phase, since the main goal at this phase is to simplify the problem, and therefore these anomalies are often omitted, as they are seen to be outside the boundaries of the design problem. How can designers consider the uncertainties and contradictions during conceptualization, as well as consider the benefits resulting from their design proposals? Designers in their sustainable design practice must consider (1) the multiple objectives and criteria; (2) the multiple users and user preferences; (3) the multiple design alternatives; (4) the complex changing global situation; and (5) the knowledge from the various disciplines comprising the design project. A collective systems thinking approach to design addresses these concerns. Consequently, the theoretical basis of the precautionary principle is directly in line with this approach to design. This presentation will discuss the epistemological and practical implications of the precautionary principle for design in this context.","collaborative design; sustainability; precautionary principle; integrated design process; fourth generation evaluation","en","conference paper","","","","","","","","","","","","","",""

In theory, Fociss has the ability for all kinds of innovations, but the implementation of radical sustainable innovations is often lagging because of complexity. Such innovation problems have often been discussed in the literature of (Knowledge) Management Studies. The ambidextrous organization provides a solutions to develop a repository of challenging, disruptive innovations. A communities-of-practice (COP) is such a solution which is based on the competences and ownership of workers, motivating them to apply their creativity and support the subsequent implementation. A Fociss scan, performed by students of Avans Hogeschool at IHC Merwede resulted in incremental innovations at which the company was already working and radical sustainable innovations, which were not further developed. However, at the same time knowledge workers were active with different sustainable innovations around greening materials while using virtual communities. We suggest to depend the initiation and further application of Fociss of the presence of work floor communities. If virtual communities are present, management may invite them to apply Fociss for their own account. This increases the repository of a variety of sustainable innovative ideas that the company can implement directly or when the situation asks for it so that it will strengthen the companys future basis.

But how a good strategy and related activities can be selected and implemented is a question that remains. Strategies and activities found in practice seem to be based on ad hoc decisions and not systematic and rational choices. Based on a qualitative literature research in environmental, social/ethical and logistics/operations management journals a conceptual framework for analyzing was developed and will be published soon. The framework integrates innovation and cooperative characteristics of the focal company and its supply network. This paper presents the first results from a survey that was held under 91 fashion/clothing companies in the Netherlands in the spring of 2010. The sector was selected because it is a known global industrial supply network, faces many sustainability aspects and many competing initiatives for managing these sustainability aspects are in place. The first results show that 75% of the respondents do not own the production phase of the supply network so for controlling this phase on sustainability aspects they depend on others. The respondents think that the personal conviction of the management and the government with regulations are the most dominating factors influencing the attention paid to social and environmental aspects in the supply network. The programmes/initiatives known best by the respondents are Oekotex 100 and the Fair Wear Foundation. Nearly all of them use or will use Oekotex 100 and only some participate in the Fair Wear Foundation programme. The scores given to thirty (innovation) statements in the questionnaire will be used to characterise the innovation power of the focal company and its supply network. These results will be related to the activities/programmes joined by this company later.","innovation; fashion; sustainability; supply network","en","conference paper","","","","","","","","","","","","","",""

Bamboo fulfills these criteria, since it is a highly renewable timber replacement material which does not cause deforestation. It simultaneously has the potential to create livelihood opportunities for both the urban and rural poor. The eco-friendly potential and image of bamboo has led to various designed sustainable products, which are made from industrially processed bamboo. Though this approach frees the product from common negative connotations associated with bamboo products, such as low cost, rustic etc., actualizing these designs requires industrial production facilities. Consequently, bamboo producer communities are pushed lower in the value chains of these products. From being final stage producers, their role becomes limited to growing the raw material, and at the most primary processing of bamboo inputs. This focuses on the role of design as an enabler to achieve holistic sustainability in the bamboo value chain in general, and in the instance of the Kotwalia community in particular. Most contemporary bamboo designs focus primarily on bamboos potential for eco-design and for commercial viability, and in consequence contribute to the unsustainability of social and cultural factors. The paper also presents the Rhizome approach, developed though the process of action research with bamboo working communities. The approach is designed to facilitate the design of products which take into consideration the social and cultural tenets of sustainability, alongside the ecological and economic tenets.","sustainability; bamboo; design; craft; livelihood","en","conference paper","","","","","","","","","","","","","",""

Generally, indicators are attributes that facilitate the understanding of a situation, by indicating - as possible - the current situation and comparing it with the desired situation. A survey performed in 2009 considered two steps: i) introduction and analysis of certain consumption indicators in 7 USP campuses, such as disposable glasses, water, electric power, built-up areas and vegetal covering, transportation and generation of waste; ii) partial data conversion into ""ecological footprint"". The data presented and discussed herein were raised with each campus, including colleges, schools and teaching and research institutes; in specific purchase and material distribution, water and power consumption and engineering sectors and green areas inside USP. The results achieved indicated that each member of the university community demands approximately 160m²/year of forest to absorb the impacts caused by resources consumption and waste production.

The cities use different technologies for lighting purposes but which technology can decarbonise them in future. Moreover, the question is, how a new technology, LEDs (Light Emitting Diodes), for lighting can shape the future green cities. What are the drivers which can determine the adoption process of LEDs technologies for lighting in India? Further the paper focuses on identifying and analysis of barriers in adoption of this technology in India. There are different technologies for lighting, but LED technology is a good option for India as well as world for shaping future green cities. There are major drivers for adopting such a technology like energy saving, emerging knowledge and awareness, better visibility and clarity, policies and new initiatives, eco-friendly and low carbon emission, long life span and long term cost effectiveness. However, the process has some barriers like high initial cost, low risk behaviour and faith deficit, culture and attitude, and existing technological regimes. Nonetheless, these barriers can be softened through collaborations, partnerships, and knowledge sharing among stakeholder along with strengthening the system through better networks.","LED technology; energy saving; foresight; sustainability; culture","en","conference paper","","","","","","","","","","","","","",""

Permeability measures the greater or lesser ease each soil, when saturated, offers the piping of water through its interstices. The permeability depends mainly on the porosity, particle size and shape of grains. Rainwater crashing into the ground can promote compaction of the surface, reducing infiltration capacity, carry out and the fines which, by their subsequent sedimentation, tend to decrease the porosity of the surface, moisten the soil surface, saturating the layers close, increasing the penetration of water and act on particles of colloidal substances that engorge wet, reducing the size of the intergranular spaces, reducing infiltration and dry, shrink, forming fissures in the ground. The presence of vegetation reduces or eliminates this effect.

Sustainability with its opportunities and challenges are not understood in its real meaning for their business.

Sustainability often seems tedious and somewhat unprofitable and therefore is taken up reluctantly just because it should? and is good? in an rather abstract manner. So sustainable actions selected are often generic?, based on standard approaches and broad sustainability philosophies?, instead of on an analysis of the companies specific own situation, ambition and strategy. We have developed an approach that helps to determine real core business related sustainability issues for an individual company. It provides a clearer focus and a better understanding of the importance of sustainability. Through that it also generates stronger internal commitment and more effective implementation. This so-called Fociss approach (focussing innovation for a sustainable strategy) starts with the actual role a company and its products have in society and economy and the changes that will occur. It is a stepwise narrowing down on theme?s, issues, sensible innovations and priorities which must then be the core of a company?s future aimed strategy for taking part in the sustainable transitions that will occur.

This focuses on the role of design as an enabler to achieve holistic sustainability in the bamboo value chain in general, and in the instance of the Kotwalia community in particular. There is a growing demand globally for products which impact sustainability positively. Bamboo fulfills these criteria, since it is a highly renewable timber replacement material which does not cause deforestation. It simultaneously has the potential to create livelihood opportunities for both the urban and rural poor. The eco-friendly potential and image of bamboo has led to various designed sustainable products, which are made from industrially processed bamboo. Though this approach frees the product from common negative connotations associated with bamboo products, such as ‘low cost’, ‘rustic’ etc., actualizing these designs requires industrial production facilities. Consequently, bamboo producer communities are pushed lower in the value chains of these products. From being final stage producers, their role becomes limited to growing the raw material, and at the most primary processing of bamboo inputs. This focuses on the role of design as an enabler to achieve holistic sustainability in the bamboo value chain in general, and in the instance of the Kotwalia community in particular.","sustainability; bamboo; design; craft; livelihood","en","conference paper","","","","","","","","","Industrial Design Engineering","","","","",""

It is the real life application of the resulting conceptual design from the main study of the ""Design for Happiness"" PhD research project. This aims to identify and propose the design characteristics which compose a product, service or system capable of contributing to our happiness hence promoting sustainable lifestyles as part of mainstream sustainable design. The paper presents the SLEUTH project; its building process, implementation and results. The building process describes six months work which developed a key team within the university that started out on a collaboration journey; they joined forces with the aim of developing and endorsing this initiative. It sets an example of the involvement required by an entire organization. The implementation process describes the actual trials of the SLEUTH project. Here, student involvement is crucial. SLEUTH has at its core the belief in collective action, and therefore it starts from the premise of giving ownership to its participants, allowing them to shape its course. This translates into making the students coresponsible for the success of the project. Finally, the data and experiences gathered during the project illustrate the results of such an initiative. These aim to contribute to finding and setting the path for universities to embed sustainability at their core; they begin to answer questions such as how to achieve a transition towards sustainable universities; how to implement, replicate, modify, initiatives such as SLEUTH in the longer term.","sustainability; lifestyles; happiness; universities; pro-activeness","en","conference paper","","","","","","","","","","","","","",""

As volume of throwaway fashion increases and quality of fabric decreases, there is a need for an innovative approach to generating and managing this type of waste. Prior work on managing post-consumer textiles concurs with the Waste Hierarchy, ie, that reusing and remanufacturing fashion items makes the least impact on energy use. A number of fashion designers have developed businesses using this approach but are usually niche market, and the environmental benefit may not be as significant as the mass markets that are currently catered for by the large retailers using the current conventional design processes and supply chains. This paper will present and examine empirical data regarding design and remanufacturing processes as practiced by fashion designers in the niche market and the design processes within the large mass market retailers and manufacturers. The paper will then consider the current fashion supply and value chain, particularly issues around design and the use of technology within it to explore opportunities for incorporating remanufacturing approach within the conventional supply chain, identifying issues and providing recommendations. This examination will identify issues around design for social sustainability and design for sustainable behavior.

The potential of a sustainability label was the subject of a study commissioned by the German Federal Ministry of nutrition, agriculture and consumer protection. Four different conceptual approaches have been identified in the framework of this study that would be applicable to a broad(er) set of product groups. The following article summarises the findings of this study. First, a review of the most important background information on labelling is given, resulting from the analysis of scientific conceptual approaches to sustainable labelling and a broad survey of existent national and international product labelling schemes. Furthermore, the need for an overarching sustainability label is exemplified on the basis of three case studies. The three selected domains for these case studies were food, toys and financial investments. Then, the requirements a sustainability label has to fulfil and the identified conceptual approaches of a sustainability label are described. The weaknesses and strengths of all approaches are discussed before general recommendations are made.","labelling; sustainability; consumer information","en","conference paper","","","","","","","","","","","","","",""

The effects-benefits include mainly the airport contribution to local employment, regional (local) economy, and consequently GDP (Gross Domestic Product). The impacts-externalities embrace local noise, air pollution, congestion and delays, land use (take), and waste. The particular indicators and their measures are specified respecting interests and attitudes of particular actors involved such as users and providers of air transport services, private and public investors, governmental organizations, local community members, lobbies and pressure groups, and general public.

Unless the population of the country is stable there is an enormous need for new housing every year. Housing production is required because of vitalisation of cities. Housing production in the Netherlands is not only luxury. Young people need new houses because the elderly stay, due to the well organized neighbourhood care-systems in their housing longer. In cities reconstruction of older neighbourhoods needs new housing too. This production crashed in the beginning of 2009 because financing of households and investors became less available. The situation has become worse because of the system of development. In the Netherlands housing developers only start building when 80% of the houses are sold from drawings. People that have the money have choice in existing stock, they do not wait two and more years before moving to a new house. So new systems are needed, systems by which the housing production is brought into motion again. With the cyclic innovation model’ in hand, lessons learned from out of other branches are suggested to use to construct such a new system. The conclusion is that houses should be developed on stock. The number of real-estate developers that search for this methodology is still small, although first steps are in progress. The new system asks for a re-shift of the land- and housing financial system, for which the housing owner takes more responsibility than before. Thereby, in the new system the housing will become a product of quality instead of quantity. Sustainable choices will unmistakably be part of such quality in future.","housing; production; sustainability; economic-crises; city-development","en","journal article","European Network for Housing Research","","","","","","","","Architecture","Real Estate and Housing","","","",""

Environmental effects being taken into account include climate change, acidification, eutrophication, disposal and dissipation. It is concluded that almost all environmental effects can be taken into account by studying the waste of feedstocks and energy caused by technological activities, like processes, and the emission and dispersion of pollutants. To underpin the qualitative investigation two case studies have been conducted: the production of aluminium and polystyrene. On the basis of the results of the case studies it can be made plausible that exergy losses and environmental impact are related. Exergy losses are a kind of environmental impact, whereas environmental impact is related to exergy loss. It is concluded that exergy loss is at least a qualitative measure that can be used in environmental policy making regarding technological processes. According to literature, exergy losses should be minimized to obtain a more sustainable development.

The choice between demolition and life cycle extension from a sustainable viewpoint","Thomsen, A.F.; van der Flier, C.L.","","2008","What is better: renovation or new construction? Following the plenary debate on the ENHR 2007 conference in Rotterdam we continued our search for the answer to this question. The choice between reuse and replacement of existing buildings is a vital but very difficult one, involving a wide range of aspects and affecting contradictory and often conflicting interests. In the past, building quality and public health played a decisive role in improvement of the housing stock, mainly by slum clearance. More recently functional and economic considerations tend to dominate. Though environmental aspects like energy consumption and building waste are of growing importance, sustainability does not seem to be a major aspect in decision making about demolition or life cycle extension up till now. In the past years we studied the decision making about demolition in the Netherlands. Based on the available literature and statistical data we analysed the actual practice in the Netherlands to identify the ‘demolishers’ and their motives. In addition to this research we made an inventory of the literature about the environmental impact of reuse and replacement. Our paper gives a concise overview of the results. Overlooking the results so far we conclude that life cycle extension by renovation and reuse of existing stock is generally more sustainable. However replacement seems to increase in the Netherlands. Therefore we discuss ways to stimulate ‘demolishers’ to give more weight to sustainability and pay more attention to reuse.","replacement of dwellings; extension of life cycle; decision making; sustainability","en","conference paper","Centre for Housing Research, UCD","","","","","","","","OTB Research Institute","","","","",""

From the viewpoint of sustainability, it may be worthwhile to lengthen the life span of many durable consumer products. Hence, there is a challenge for designers to strengthen the bond between consumers and their products through the product design process. In the present study, we develop a scale to measure consumer-product attachment, and we identify and measure seven possible determinants of attachment: enjoyment, memories to persons, places, and events, support of self-identity, life vision, utility, reliability, and market value. Only memories and enjoyment contribute positively to the degree of attachment. The highest levels of attachment are registered for recently acquired products (<1 year) and for products owned for more than 20 years. For new products, enjoyment may be the main driver of attachment, whereas for old products memories may be more important.","attachment; product experience; sustainability; memories; enjoyment","en","journal article","Chinese Institute of Design","","","","","","","","Industrial Design Engineering","","","","",""

(promotor)","2008","This thesis describes the challenge to apply a breakthrough in the synthesis of acidic zeolitic catalysts in the development of a sustainable process for dimethyl naphthalene-2,6-dicarboxylate. BiModal POrous Materials (BIPOMs) are zeolitic materials, which provide highway access to confined catalytic sites, thus allowing selective reactions with high rates. Much attention was paid to the selection of a suitable model system. It should be representative for a real existing industrial problem with sustainability, while at the same showing the potential of the new catalytic approach. Diisopropylation of naphthalene was chosen as a model system. There are numerous claims in literature for shape-selective diisopropylation of naphthalene with H-mordenite, but the reaction rate is too low to allow industrial application. Furthermore Kureha operates an industrial process for the production of a mixture of diisopropylnaphthalenes, and finally SRI has published a process cost study on Amoco technology leading to 2,6-dimethylnaphthalene carboxylate. Contrary to the claims in literature, the reaction was not shape selective with H-mordenite, but controlled by the relative stability of the isomeric diisopropylnaphthalenes. However the applicability of the BIPOM concept turned out to be very successful. The BIPOM catalyst not only showed a >200 times increase in yield compared to its parent normal zeolite, but also showed a significant yield increase compared to the best available zeolitic catalyst (H-USY). Explorative crystallisation experiments indicate that the production of pure 2,6-diisopropylnaphthalene seems possible. Thus a new process for the industrial production of dimethyl naphthalene-2,6-dicarboxylate was designed and evaluated. The base case scenario, though slightly better than the Amoco-technology, is still not economically attractive. However in close analogy to the existing Kureha process, the higher yield scenario seems realistic, leading to an ROI of ~ 12%, close to the limit of an economically attractive process. The final conclusion of this work is that violation of the atomic efficiency, by inherently loosing 4 carbons out of 6, cannot be compensated by an otherwise excellent catalytic concept.","heterogeneous acid catalysis; dipn; process evaluation; sustainability","en","doctoral thesis","","","","","","","","","Applied Sciences","","","","",""

This is performed within the Delft Cluster project “Sustainable development of North sea and coastal zone”. The formulated problems are: 1. Stability of geocontainers under wave attack and/ or currents. 2. Positioning accuracy of geocontainers. 3. Required strength of the geotextile during the placement of geocontainers. 4. Sustainability of geocontainers with respect to UV load, ageing process and mechanical loads. The first subject is suitable for research in Delft Cluster 2. Taking in mind that wave loads are a larger problem with respect to the stability than currents, the former is selected for research. The second and third topic have been investigated in Delft Cluster 1. This resulted in an improvement of knowledge. The main goal in the long run, providing a thorough insight in the risks of applying geocontainers, can be realised by backing up the research with practical experience and scale model tests. The costs of these are however too much to include in Delft Cluster 2. UV loads and ageing processes of geotextile are subjects in the domain of the manufacturers of geotextiles.

Based on the assumption that physical structures have a direct effect on patterns of social organization and behavior and vice versa, this research represents an instrumental approach to the problem of fragmentation in the city, by proposing concrete actions to gain connectivity, in the form of urban projects: connectivity-oriented urban projects. The method of investigation is research by design, with the induction of potential solutions to the problem of fragmentation in the urban tissues in the form of briefs and hypothetical design of urban projects. Briefs and designs presented in this thesis are related to a research design integrated by a theoretical cycle and an empirical cycle. In each one of these cycles, the phases of analysis, design, strategy and evaluation are present, as in a spatial planning cycle.

This results in longer distribution distances, which lead to a higher relative importance of this phase in the entire life cycle. To make this phase as efficient as possible, products should be packed as volume efficient as possible, which means small boxes. Secondly, retail formats for CE products change into large budget-oriented stores selling products in the box. Here the packaging has to sell the product, which calls for bigger, shinier boxes. Obviously the combination of these developments leads to design conflicts.

(promotor); Van der Hoven, M.J. (promotor)","2005","The goal of this research is to obtain insight in how engineers deal with ethical issues in daily engineering design practice. It is reasonable to assume that ethical issues and the way engineers deal with them depend on characteristics of the design process. I have made use of Vincentis dimensions to characterize different design processes: design type and design hierarchy. In normal design the working principle, how the product works, and the normal configuration, the shape and parts of the product, are known. To obtain empirical data, case studies have been conducted. Two radical design processes, one high level conceptual design (an ultralightweight sustainable car) and one lower level design (a lightweight trailer) have been studied. Besides these two radical design processes, two normal design processes also differing in design hierarchy have been studied (design of piping and equipment for the (petro)chemical industry and the design of a bridge). In the radical design processes ethical questions are especially related to operationalisations of criteria such as safety and sustainability and trade-offs between design criteria. These operationalisations and trade-offs are made using internal design team norms. These internal norms are based upon design experience, personal experience and education of the design team members. In the normal design processes a regulative framework is used. A regulative framework consists of European and national regulation, codes and standards, and interpretations of regulation and code given by certifying organisations. The regulative framework provides operationalisations and some guidelines for trade-offs. This does not mean that all ethical issues can be dealt with by referring to the regulative framework. Some decisions that engineers make for example concerning safety are not covered by the regulative framework. Parts of the regulative framework are inconsistent and ambiguous. Another important ethical issue is that it is not clear whether the regulative framework is accepted by all affected actors. The descriptions of the design processes are used to formulate ideas on the conditions for warranted trust in engineers making normal and radical designs.","safety; sustainability; trust","en","doctoral thesis","","","","","","","","","Technology, Policy and Management","","","","",""

Although sustainable building has been high on the national political agenda, and although this was in a period of intensive policy developments in the Dutch social sector, there are indications that sustainability plays only a minor role in housing management decisions (Sunikka and Boon, 2002 and 2003). This paper is about recent strategic innovations in housing stock policy and investment decisions of social landlords, and the role of sustainability in these innovations. The paper deals with several case studies on this subject, and also goes into a recent survey among social landlords on investment policy and technical management, which gives a more comprehensive picture of the sector. We compare the results with those of an earlier, similar survey, held in 1997 (Straub, 1997). We conclude this paper with some recommendations for enlarging the role of sustainability in housing management.","sustainability; management; landlord; investment","en","conference paper","","","","","","","","","OTB","","","","",""

An exploration of the potential for factor 20 environmental improvement of office accommodation","Van den Dobbelsteen, A.A.J.F.","Cauberg, J.J.M. (promotor); De Jonge, H. (promotor); Kristinsson, J. (promotor)","2004","Sustainable development is the goal of a balance between economy and the environment, whilst establishing a better spread prosperity across the world. In order to make this possible, the environmental load of our commodities needs to be reduced by a factor of 20. This factor 20 can also be translated to the office market. The PhD research presented in this thesis focussed on finding solutions effectively contributing to factor 20 environmental improvement of office accommodation. In order to determine the current environmental performance and to find the main aspects and building components causing environmental damage, twelve offices designed without a special focus on sustainability were environmentally assessed. This case study reveals that recently constructed offices are hardly more sustainable than in the reference year 1990 and that, on the basis of a lifespan of 75 years, almost 80% of the environmental load of office buildings is related to energy consumption. Heating (and cooling), lighting and use of equipment (mainly computers) together constitute approximately 90% of energy consumption. The supporting structure of a building causes almost 60% of the environmental load of building materials. Consumption of water proves unimportant to the environmental performance. The age and expected service life of a building had not yet been accounted for in environmental performance. This thesis presents a methodology for the account of these factors of time, facilitating decisions about, for example, renovation and re-use of an existing building versus demolition and construction of a new building. On the basis of this methodology it can be established that with an eventual service life of the building of around 20 years - a realistic value for modern offices - the use of building materials becomes equally important as energy consumption. Studies indicate that there are two main service life strategies that effectively improve the environmental performance of offices: design of long-lasting monumental buildings with an over-sized structure, or buildings with a demountable or short-cyclic supporting structure. The lifespan of components other than the supporting structure play no significant role in environmental performance. Theoretically, the use of sustainable energy resources can lead to more than a factor 20 environmental improvement of energy consumption. Many technologies and solutions are known and available. The supporting structure of a building can be improved by choosing optimal structural spans and combinations of building materials for the structural components. A maximum difference of a factor 4.5 can be found between favourable and unfavourable, yet common, solutions for supporting structures. Best solution found is a floor of TT slabs spanning the entire building depth, supported by timber beams and columns. For offices this is a flexible solution as well. Further enhancements will be possible through the use of new building materials. As a result of different effects, the basic shape of a building does not substantially influence its environmental performance. When comparing different building heights, however, an optimal number of stories can be found for each net floor area required for an office organisation. In the case of large buildings, the maximum difference between favourable and unfavourable solutions is around a factor of 1.6. The use of space inside offices defines the size and geometry of the building. Layout principles other than the cellular office enable substantial environmental improvement of the use of building materials. As case studies of European redevelopments around nodes of public transport reveal, on the urban scale, intensive and multiple use of space can lead to significant environmental improvement related to travel and the green area preserved outside the city. In regards to average mono-functional urban plans, stacking and mixing of functions offer the better opportunities for sustainability. Comparison of telework concepts with traditional concepts for office work demonstrate that limited improvement can be achieved in terms of employee travel and the use of space, building materials and energy. The best achievements are possible through complex forms of telework based on distributed working. In this case, office workers basically work where they are for business: with the client, in a business centre, at home, or anywhere in-between. In the near future, the best opportunities for sustainable office accommodation will be a new sustainable organisation of office work. This should be based on the concentration of general, shared office functions at nodes of public and private transport, together with home and district offices as basic workplaces for office employees, and virtual offices anywhere. In this concept, the traditional central office is transformed into a clubhouse office, where only the basic functions for management, administration and support of the office are accommodated, and where employees meet for their corporate identity and exchange of experience. This much smaller central office can be located in the heart of cities or at the already mentioned business nodes. The new organisation of office work leads to environmental improvement by a factor of 2, not yet taking into account potential additional improvements of the space, time and technology factor. Beside the environmental benefits, this new office work concept leads to revaluation and animation of urban areas, and offers more freedom with regard to the combination of business and private activities. A final assessment was done of the overall improvement potential through a combination of measures, starting with the organisation of office work, followed by solutions for an efficient use of space, optimal building designs and technologies, and finally based on sustainable strategies for the time factor. This assessment indicates that, on the basis of an optimal combination of measures, environmental improvement by a factor of 50 is possible. A less optimal combination still makes factor 10 possible. Therefore, the factor 20 seems feasible for office accommodation. Decisive to this end-result is an integral strategy, in particular involving the use of sustainable energy resources, a wiser approach to aspects of the lifespan, and a new organisation of office work. And people of course will have to do it.","sustainability; factor 20; environmental assessment; environmental impact; environmental load; environmental cost; reference; office; time factor; lifespan; service life; technology factor; energy; building materials; water; building geometry; space factor; office layout; multiple use of space; intensive use of space; organisation of office work; office concept; telework; effectiveness","en","doctoral thesis","Copie Sjop, Delft","","","","","","","","Architecture","","","","",""
