Purpose: The application of circular building adaptability (CBA) in adaptive reuse becomes an effective action for resource efficiency, long-lasting usability of the built environment and the sped-up transition to a circular economy (CE). This paper aims to explore to which extent CBA-related strategies are applied in adaptive reuse projects, considering enablers and obstacles. Design/methodology/approach: A stepwise theory-practice-oriented approach was followed. Multiple-case studies of five circular adaptive reuse projects in The Netherlands were investigated, using archival research and in-depth interviews. A cross-case analysis of the findings was deductively conducted, to find and replicate common patterns. Findings: The study revealed that configuration flexibility, product dismantlability and material reversibility were applied across the case studies, whereas functional convertibility and building maintainability were less applied. Low cost of material reuse, collaboration among team members and organisational motivation were frequently observed enabling factors. Lack of information, technical complexities, lack of circularity expertise and infeasibility of innovative circular solutions were frequently observed obstacles to applying CBA. Practical implications: This paper provides practitioners with a set of CBA strategies that have been applied in the real world, facilitating the application of CBA in future adaptive reuse projects. Moreover, this set of strategies provides policymakers with tools for developing supportive regulations or amending existing regulations for facilitating CE through adaptive reuse. Originality/value: This study provides empirical evidence on the application of CBA in different real-life contexts. It provides scholars and practitioners with a starting point for further developing guiding or decision-making tools for CBA in adaptive reuse.

The pressing need to implement a more circular economy has led to advancements in the research field. In the spatial context, sharing spaces and access-over-ownership models have the potential to mitigate the detrimental environmental impacts of space use. This study aims to adapt an existing theoretical framework on access-based consumption to the spatial context. We utilise a qualitative case study approach exploring a variety of shared spaces from Northern Europe. Our findings suggest that shared spaces and their organisation are inherently fluid. The study further reveals that the physical object of sharing, even in the case of shared spaces, is being partially replaced with virtual and hybrid solutions. In fact, a hybrid solution seems to enable organisations delivering shared spaces to be more dynamic. Finally, we find that in the spatial context, two types of political consumerism prevail: decommercialization of spaces on the one hand and promoting environmental sustainability on the other. This study is the first to suggest a holistic framework for access-based consumption in the spatial context. The findings will be useful to scholars and practitioners engaged in developing, owning and providing services for shared spaces.

Purpose: Since corporate real estate management (CREM) emerged in the 1990s, it has been modelled in many ways. The Delft model views the corporate real estate management function as a coordinator of four distinct accommodation perspectives. Although the model has been used in education and practice for years, there is no consensus on its interpretation and application, and various versions circulate. This paper aims to first reconstruct the history of the conceptualisation of the Delft CREM model and then seeks to develop an understanding of its nature that provides clearer interpretations of the model. Design/methodology/approach: Because the developers of the Delft CREM model did not maintain archives, the reconstruction of the model’s genesis is based on the developers’ publications from 1985 to 2015 and eight semi-structured interviews conducted with these developers in 2017 and 2018. The collected information, which was by its very nature incomplete and imperfect, was triangulated, contextualised and assembled chronologically. This served as the basis for an analysis of the model’s nature, which in turn generated a list of practical implications for its future application. Findings: The historical reconstruction revealed two parallel but distinct lines of reasoning, whose resulting models appear similar but are distinct. One line of reasoning models CRE viewpoints, while the other models CRE management activities, i.e. the first line of reasoning models CREM across the organisation, while the second models CREM within the function. These two lines of thought have converged in the research-through-design approach of the developers, which evolved against the backdrop of a growing interest in the contribution of organisational resources to organisational objectives and the emergence of the demand-supply model in management practices in general and in the built environment in particular. Research limitations/implications: The research is limited to reconstructing the genesis and analysing the nature of the Delft CREM model. It is not intended to provide a conclusive narrative, update the model or compare it to other CREM models. As is typical in oral history, it is based on imperfect documentary evidence and imperfect recollections. The reconstruction and analysis are stepping stones towards a more precise interpretation and application of the model in both research and practice, and may eventually contribute to its evolution. When using the model, it is recommended to (1) be clear about whether the model applies to the CREM department, the entire organisation or the organisation’s environment; (2) be clear about what is being modelled (activities, viewpoints or something else); and (3) use labels that reflect the selections made in (1) and (2). Originality/value: The value of this paper lies in the historical reconstruction of the intentions of the developers of the four-view scheme, including the detailed analysis of its consecutive graphical representations and the investigation of its relationship with the seminal strategic alignment model.

Purpose: Adaptability is an inherent quality in building circularity, as adaptability can physically facilitate the reversibility of materials in a closed-reversible chain, also called “loops”. Nevertheless, positioning adaptability in circularity-oriented models could overlook some of the contextual considerations that contribute to the utility for the built environment. This paper reconceptualises building adaptability to incorporate circularity, in order to facilitate for the resource loops whilst preserving the long-lasting functionality in buildings. Design/methodology/approach: An integrative literature review on adaptability and circularity of buildings was conducted using systematic search approach. From the initial database of 4631 publications, 104 publications were included for the final analysis. A comparative analysis of definitions and determinants of both concepts was conducted to reconceptualise circular building adaptability. Findings: The findings of the literature study show that incorporating circularity and adaptability is possible through 10 design and operation determinants, namely configuration flexibility, product dismantlability, asset multi-usability, design regularity, functional convertibility, material reversibility, building maintainability, resource recovery, volume scalability, and asset refit-ability. The study concludes that considering the defined determinants in a holistic manner could simultaneously facilitate: building resilience to contextual changes, creation of asset value, and elimination of waste generation. Originality/value: This paper expands the relevant bodies of literature by providing a novel way of perceiving building adaptability, incorporating circularity. The practical value of this paper lies in the discussion of potential strategies that can be proactively or reactively employed to operationalise circular building adaptability.

Purpose: It is widely recognized that interior office space can affect health in several ways. Strategic and evidence-based design, including explicit design objectives, well-chosen design solutions and evaluation of results, aid realization of desired health effects. Therefore, this paper aims to identify possibly effective interior design strategies and accompanying design solutions and to provide examples of effectiveness measures. Design/methodology/approach: A literature sample of 59 peer-reviewed papers published across disciplines was used to collect examples of workplace design features that have positively influenced workers’ well-being. The papers were grouped by their health objective and design scope successively and their theoretical assumptions, measures and findings were analyzed. Findings: Four main workplace design strategies were identified. Design for comfort aims at reducing or preventing health complaints, discomfort and stress, following a pathogenic approach. It has the longest tradition and is the most frequently addressed in the included papers. The other three take a salutogenic approach, promoting health by increasing resources for coping with demands through positive design. Design for restoration supports physical and mental recovery through connections with nature. Design for social well-being facilitates social cohesion and feelings of belonging. Design for healthy behavior aims at nudging physical activity in the workplace. Originality/value: By drawing complementary perspectives and offering examples of design solutions and effectiveness measures, this paper encourages workplace designers, managers and researchers to take a transdisciplinary and evidence-based approach to healthy workplaces. It also serves as a starting point for future empirical research.

Purpose
Triggered by public concerns over office workplace safety during the COVID-19 pandemic, this study sheds light on the office workplace environment and aims to investigate how organisations respond to forces from the external environment (impacted by the COVID-19 pandemic) and how they modify their office workplace management strategically and operationally to suit the stakeholders’ needs and future development in the post COVID-19 period.

Design/methodology/approach
A desktop study was conducted to provide the framework for the in-depth interviews with five corporate real estate (CRE) managers and three workplace consultants. Thematic analysis including coding technique was adopted to analyse the qualitative data.

Findings
The findings show that during the COVID-19 pandemic, most of the intended and implemented office workplace modifications are mainly related to two types of risk control: administrative control and personal protection. At a strategic level, organisations react to the external forces by re-modelling their businesses and working towards re-orienting their CRE strategies, such as portfolio transformation, agile portfolio strategies and redesign of the office workplace, etc.

Originality/value
This is a topical and timely study that presents the general practice of office workplace modification during the COVID-19 pandemic, as well as the related CRE management (CREM) strategies developed for the new normal. The findings obtained through in-depth interviews have well supported the CREM strategic alignment theory. It is foreseen that office workplace management will encounter other challenges due to uncertainties of the COVID-19 pandemic. The findings of this study provide a practical lens to look at the future changes of office workplace environment.

This research aims at developing a real estate management theory that overarches the different classes of real estate management like e.g. corporate real estate (CRE) management and housing management, who all operate within a specific narrative, apply a particular range of concepts and terminology, and refer in their own way to general theories like asset and portfolio management. These specificities create barriers for communication between the different classes of real estate management and hamper the exchange and development of knowledge in the field, what we consider undesirable. The challenge of developing a broad real estate management theory is to avoid that little more is done than to repeat general management, economic or sociological theories. The aimed broad real estate management theory should approximate the concreteness of the specific theories and cover their core, while still being relevant for practice, research and education. For this research, real estate management is considered the ongoing process of aligning the built environment and the needs of users, which happens at all scales of the built environment, for all types of users, and for all real estate aspects such as location, cost, function, time and quality. Based on this definition, the research will addresses three components: demand side, supply side and the delivery models that coordinate both sides. The research on the side of the real estate demander searches for similarities and differences between e.g. the way the demander is organised internally, the real estate procurement is executed, what is outsourced and why, what performance criteria are used, how financial markets are accessed. The research on the side of the supplier of the built environment may address topics like e.g. what is the relation of the supplier with the user, what drives production, what are context constraints, what is the status of the sustainability discourse. The search for similarities and differences in the delivery may address e.g. what models are in place, what types of institutions operate in this delivery, who intervenes in this alignment and why, what is the nature of the markets, what is the role of state intervention, what type of alignment is searched for, what performance criteria are used. The comparison of different classes of real estate management may reveal e.g.: that theories on CRE management subsequently position the CRE management department inside the user’s organisation boundary, whereas theories on housing management position this group most often outside the households’ boundary; that current practices in CRE and housing management both strive after a portfolio of conventional assets and keep away from the representative objects like monuments; that there is a trend that households want to be more involved and co-producing their house than before and thereto want to bypass the current institutional setting (sort of insourcing, self-production), whereas within organisations the trend has been for decades to less involve in the management of their accommodation and to rely on the possibilities offered by the CRE and related services market, although since a few years in-sourcing and self-provision seem to be revalued; that there is recent trend that private companies engage in the delivery of housing for their employees to deal with failing housing markets like they did in the beginning of the 20th century, and that households are re-initiating work at home, for which they need a different type of dwelling; both types of users seem to breach the institutionalised division of actors by real estate function installed for almost a century. This type of observations – and many more and of very different natures – trigger an explanation of causes and mechanisms, and together with the main theories used in the different classes of real estate management (Pestoff, 1993; Brandsen et al., 2005; Henderson & Venkatraman, 1993;…) they are the basis for building the aimed broad real estate management theory. In concreto the research method consists of theory design, academic literature study and interviews with academics. @en

Use of resources is one of the greatest challenges globally. Circularity aims to reduce resource input to the system and to avoid resource losses in the system. An extended concept of waste from the Toyota Production System is applied to real estate management (REM) to reduce the resource input and to manage for long-term circularity. The extended waste concept identifies waste as excess use of any type of resource, including human resources and time. This resource capacity is used for both work that adds value and for work that does not. Waste reduction means that the use of resources is minimised especially in work that does not add value. In other words, the available resources are released resulting in a re-created resource base, which is mobilised into the value-adding work. In terms of alignment theories in corporate real estate management, this means horizontal alignment on three levels: (1) work level, (2) system level, and (3) employee level. The extended waste concept on these three levels motivates organisations to improve their processes and strategic routines, resulting in structural and long-term advantage to sustain the transmission from linear economy to circular economy.@en

Purpose – Building adaptation has been viewed as a strategy towards the sustainable development and circular economy, as it contributes to the reuse of the built assets and reduce their environmental impacts in the long term. Relevant research focused on defining the determinants of the sustainable building adaptation, while the comprehension of that from the perspective of the circularity is still needed. Thus, this paper intends to present a reconceptualisation of the built environment adaptability through incorporating determinants of circularity. Design/methodology/approach – An integrative literature review, using systematic search, was conducted on relevant sources to the adaptability and circularity domains, to identify potential determinants of circular building adaptation and incorporate them in a novel conceptualisation. Integrative literature, as a research approach, was followed to critically analyse the components of both concepts, and thus, conceptually synthesis their determinants in an integrated formulation. Two matrices were developed to depict the determinants of both concepts with their brief description, and thus, the conceptual incorporation was accordingly conducted. Findings – Based on the initial literature review, it was concluded that circular adaptability of buildings comprise a series of technical, physical, legal, legislative functional and spatial determinants that should be incorporated with a set of the R-strategies to efficiently closing the loop of the resource consumption. The R-strategies could encompass the reuse, refurbish, recycle and remanufacture of the building components. Research limitations/implications – The paper provides a basic comprehension of the building adaptation within the context of the call for circular built environment, which can be a foundation for the development of pragmatic strategies towards achieving the circular economy prospects.@en

The increasing competitive pressures and dynamic user preferences have resulted in a fast-paced and uncertain business environment. In the face of these circumstances, organizations are looking into alternatives to incorporate flexibility to become more adaptive and responsive to change. In this line, co-working, typically associated with freelancers, entrepreneurs, and startups, has become a particularly interesting alternative in the market that has caught the attention of corporate occupiers. Therefore, the aim of this paper is to identify co-working strategies that can be implemented as part of the corporate real estate portfolio, in alignment with the flexibility demands of the organization. This nascent research topic is studied through 5 qualitative case studies including in-depth, semi-structured interviews with corporate real estate managers and related case documentation. The results evidence the different motivations that the organizations have when incorporating co-working in their property portfolio. As seen across the cases, organizations in different stages of maturity are implementing co-working as the main office location or as a temporary or complementary space solution, through six different strategies: (1) Swing Space, (2) Expansion Space, (3) Core and Flex, (4) Touchdown Space, (5) Testing Market, and (6) Temporary Projects and Staff. This research evidences that each strategy plays a specific role in the corporate real estate portfolio and implies different sources of flexibility that support the physical, functional, and financial flexibility demands of the organization@en

Health is a trending topic in the office market, yet scientific research on healthy offices is scattered. This study undertakes a systematic literature review on the relationship between the interior space of offices and physical, psychological and social well-being. The review identifies the characteristics of interior office space that have been studied in relation to employee health, and outlines the empirical evidence. Of 2816 papers in the database, 50 addressed the relationship between interior office space and health and did so based on six features: layout, furniture, light, greenery, controls and noise. Evidence on the relationship between interior space and health has accumulated only within a few topics. On the one hand, open-plan offices, shared rooms and higher background noise are negatively related to health. On the other hand, positive relationships are found between physical well-being and aspects that encourage physical activity; between physical/psychological well-being and (day)light, individual control and real/artificial greenery; and between social well-being and small shared rooms. In measuring health, physical well-being is predominant. Similarly, studies have predominantly aimed to prevent health problems rather than enhance health. Overall, the related research is in a nascent stage. Further research is required to verify claims about healthy offices.

Purpose: Health has taken a leading role in office design and investments. In the knowledge-intensive world, employees are acknowledged to be organisations’ most important asset, their health and well-being is an important investment in the current office market. In this paper, the purpose is to identify different design strategies for creating healthy workplaces to give direction to design and future research in this rapidly expanding area.Theory: Workplace design is able to harm or support health in different ways. For instance, exposure to toxic emissions, loud noise and daylight directly affect physical health. Mental health is affected by work environments causing or buffering stress, or by constraining or fulfilling basic human needs. Psychological theories of arousal, environmental load and stress explain how the amount and appraisal of stimuli affect wellbeing. An imbalance between demands imposed and resources offered by the working environment can cause burnout. Indirectly, the office space design could influence health by nudging healthy behaviour. Design/methodology/approach: A literature review was conducted to deduct design strategies for health from existing research on health effects of workplace design. Academic search engines were used to find peer-reviewed papers that measured the relationship between features of interior office space, and health conditions or healthy behaviour of the office workers. From the initial database of 2816 papers, 59 were included for further analysis.Findings: Related to interior office space, three design strategies for employee health were identified. The most traditional strategy, designing for comfort, aims to create a comfortable environment by fulfilling the bodily and psychological needs of the users, and preventing harm, stress, and frustration. Designing for revitalization aims to decrease office workers’ stress by offering an environment that supports physical recovery and renewal of psychological resources. Designing for healthy behaviour aims at stimulating physical activity, healthy nutrition, or relaxing activities.Originality/value: This research contributes to a nuanced and positive perspective on healthy offices. By identifying strategies for prevention of harm as well as strategies for creating positive influences, it reveals promising directions for further research and salutogenic design. By outlining existing empirical research it provides a foundation for evidence-based workplace design within the different design strategies@en

Purpose
Global megatrends such as urbanization and ageing of the population result in fast-paced demographic changes, which pose different types of challenges for different regions. While many rural municipalities bear the burden of under-used buildings, cities are in a hurry to develop new ones to meet new space demands. The purpose of this paper is to assess the potential of relocatable modular buildings to address these challenges, following the principles of circular economy, while at the same time offering usability.

Design/methodology/approach
This multiple case study explores existing relocatable modular health-care buildings in Finland. The case buildings host hospital support functions, imaging services, a health-care centre and a care home. The primary data comprise 21 semi-structured interviews and observation during factory and site visits.

Findings
Based on the findings, relocatable modular buildings have many benefits and provide a viable option for cities and municipalities struggling to meet their fluctuating space demands. Some challenges were also identified, mainly derived from the dimensional restrictions of the modules.

Originality/value
This research contributes to the emerging body of knowledge on circular economy in the built environment. More specifically, the research provides a very concrete example of circularity and details a framework for usable and relocatable modular buildings. In conclusion, relocatable modular buildings could solve the challenges posed by quickly changing demographics in different types of regions and deliver both usability and circularity.@en

Every business needs a place to operate. The management of corporate operational assets is called Corporate Real Estate Management (CREM). In the era of sustainability, smart use of real estate as the second-largest asset of corporations is needed. The purpose of the paper is to reconceptualise CREM alignment to feature the waste concept in smart use of CRE resources. This research is limited to the conceptual analysis of CREM alignment. The reasoning is based on integrative literature review. In general management theories, alignment is divided between vertical and horizontal alignments within and across organisations. In CREM literature, vertical alignment within an organisation is dominant while horizontal alignment within an organisation and across organisations has gained minimal attention. The conceptual analysis indicates that there is plenty of waste in CREM. Lean aligns especially horizontally and offers a way for smart alignment, i.e., a smart use of CRE resources including not only the use of materials and energy but also the use of human resources with their social capital.

Purpose: As corporations change their way of working, the importance of corporate real estate (CRE) management has increased. Hence, there is a need to structure the existing knowledge and to identify the latest developments in CRE research. This paper aims to identify the major developments and changed paradigms in CRE research in 2005-2015. Design/methodology/approach: A systematic literature review is conducted, including papers from seven journals. In three sequential scans, papers were identified for the final analysis, keeping 99 of 1,667 papers. Findings: Based on nine identified developments, two paradigm shifts were found. The shift from cost minimisation to value delivery was identified. Besides solving current problems, value delivery aims to capture the future value and prevent future problems. The second paradigm shift is from buildings to people. Before the shift, buildings refer to value delivery as a transaction, while the shift to people highlights the aim to provide value-in-use. Research limitations/implications: This paper focusses on corporate offices, excluding retail, health care, education, publicly owned facilities, etc. This research is limited to CRE research. Therefore, the results are applicable to CRE research but do not cover the developments in practice. Practical implications: For practitioners, this paper offers a possibility to develop their RE strategies by reflecting their current practices with the identified developments and paradigms in the CRE literature. This paper suggests to conduct a similar research in practice to compare the underlying paradigms. Originality/value: This paper is based on a systematic literature study, and summarises developments in CRE research over the past 10 years.

Purpose: The purpose of this paper is to analyse how the concept of 'healthy offices' features in Facility Management (FM) research and practice, and to what extent facility management journals contain academic (research) papers that show that FM can indeed make the office a healthier place to work. Design/methodology/approach: This paper is based on a systematic literature review among Facilities, Journal of Facilities Management, and Journal of Corporate Real estate over the period 2007-2017. Findings are compared to the WELL-Building Standards and recent reports published by practitioners. The papers and reports are first scanned for relevance; relevant papers are analysed by three independent researchers, using content analysis. Findings are compared and synthesis is made. Findings: Based on the literature study, we conclude that current literature primarily supports the absence of unhealthy aspects, like for example air quality and indoor environmental quality. Sustainability and plants are part of this topic. Furthermore, we ascertain that FM suppliers focus on office design that supports employees' health, and on influencing people’s behaviour, whereas academic papers hardly pay attention to these topics. The results of the analysis show a need for academic research on 'healthy offices'. Practical implications: The research focuses on those elements of healthy offices that may be influenced by facility management. Originality/value: Although the topic ‘healthy office’ is currently a trend, research on the topic is largely focussed on indoor air quality and indoor environmental quality, with a focus on the effects on productivity, not so much on health of employees. @en

Purpose: New ways of working challenge workplace management: increasing mobility and diminishing organizational boundaries require re-evaluation of both workplace design and service delivery. However, structures and processes of workplace management are still traditional, and managers, together with outsourced facility service providers, often do not succeed at fulfilling the needs of mobile employees. The aforementioned changes stimulate discussions in many areas in both industry and academy. Nevertheless, workplace literature from business perspective seems to be scarce. In this paper, the focus is on workplace service offering for mobile knowledge workers. This paper aims to study the current state of workplace servitization. To answer this, the authors identify value offering elements that are used in office business market to deliver workplace as a service. Design/methodology/approach: This study follows multiple case study methodology including five case studies. Primary data were collected through interviews with workplace service providers. Secondary data included observations and publicly available data. The authors took business model design approach to study selected business offerings. Findings: The results indicate that workplace business models include elements of servitization on various levels. Physical space is no longer the central offering in the office business; instead, it acts as a component on which the service portfolio is built. The highest value from workplace comes from experience-related service offerings. Originality/value: Academically, research contributes to the workplace management studies by providing servitization perspective to a topic previously approached with a more technical and psychological point of view. This study can also support service providers and customer organizations in their quest to make service provision more flexible and experience-oriented.

Purpose: Burnouts are on the rise and now make up for over 50% of the long-term sicknessleave in The Netherlands. Little is known about the job demands and resources regarding thephysical work environment in offices. The aim of this paper is to study the impact of thephysical work environment of offices on the employee’s health and wellbeing. More specific,to find out which elements of physical work environment do have a positive or negative impacton physical or mental health and wellbeing of office workers based on empirical evidence. Design/methodology/approach: The study is based on systematic literature review includingapprox. 2600 papers published in international scientific journals across different disciplinesfrom 1993 until today. The papers were reviewed through three scans. In the first and secondscans, papers were included or excluded based on the title and abstract. In the third scan, theentire paper was read resulting approx. 200 papers to include for the final analysis. Findings: The study expects to find the main elements of the physical work environment thatimpact on employees’ health and wellbeing based on the empirical evidence. The preliminaryfindings show that the past ten years the amount of research in this field has grownsubstantially. More studies seem to focus on indoor environment, especially indoor climate,than on elements of workplace design like layout, furnishing or greenery. Recently design toactivate the employees has become a popular subject. Practical implications: For practitioners, such as designers, HR professionals and facilitymanagers, the systematically collected evidence about the health effects of the physical workenvironment inform and enhance workplace design and thereby contribute to a healthier workenvironment in offices. For researchers it shows which physical elements of the officeenvironment are studied well and which elements may need further investigation related tophysical or mental occupational health. Originality/value: Scientific research about the impact of building features on health andwellbeing is often limited to healthcare facilities (healing environment). This studysystematically collects the empirical evidence from the impact of office on health andwellbeing across different discipline.@en
