Unclogging the grid
A study on how deep energy renovations can reduce the load on the electrical energy grid and create a self-sufficient building
These research results were developed into a design for the renovation of a post-war appartmentbuilding in Haarlem Schalkwijk. In the new design other topics like densification, flexibility and climate adaptation were addressed as well to improve the post-war neighbourhood. This design is a base for a bigger renovation strategy that could be implemented in multiple post-war neighbourhoods in the Netherlands.

To implement the workflow, a novel stacking algorithm is designed using COMPAS [5], an open-source Python framework. It positions quadrilateral voussoirs on a funicular geometry’s thrust surface in a sequential one-by-one manner. The placement is guided by three global design principles. First, a pair of opposing voussoir sides are aligned parallel to the force flow while the remaining pair, which represents the load-transferring faces, is aligned perpendicular to it. This is done to prevent sliding failure. Second, the thrust surface is confined within the middle third of the voussoir to prevent the formation of hinges and cracks. Third, voussoirs are cut into hexagonal shapes and staggering is ensured among neighbouring voussoirs to create an interlocking geometry. Once a structure is completed, its stability is ensured by finding a compression-only equilibrium using the Rigid Block Equilibrium method [6].
The algorithm is then studied using various stocks with different voussoir dimensions of both regular and irregular side lengths, various deployment strategies that enable the user to customize the launch of the algorithm, and different thrust surface shapes. It is primarily assessed what fraction of the initial concrete volume can be retained in the structure. It was found that on average 47% of volume per voussoir is retained and that voussoirs of regular dimensions retain approximately 5% more of the initial volume. Minor differences exist in the results among different thrust surfaces with shapes of more uniform force flow retaining more concrete. Furthermore, smaller voussoirs mostly sized 0.7x0.7x0.2m required 20% less volume to construct a shell than a stock of 1.0x1.0x0.2m voussoirs. At the same time, the smaller stock required almost double the amount of voussoirs, thus, indicating competing goals that require the decision-making of the designer.
Next, high-level waste minimization was performed by checking if offcuts could be used to create other voussoirs from the remaining structure or if they could be returned to the stock for future placement. A pessimistic and an optimistic scenario were studied and it was found that 70-85% of the initial voussoir volume can be efficiently retained within the shell and the stock.
These results served as the basis for reflecting on how the stacking algorithm influences the suggested workflow by bringing design and fabrication-specific constraints to an earlier design phase. It is described that to improve the retained volume the designer can, first, alter their way of deploying the algorithm, second, modify the input geometry, third, custom select what stock is used for placement, and, fourth, inform the contractor of the level of detail to which a building should be deconstructed and post-processed. Thus, a designer is brought closer to the construction process, and incentives for a more collaborative cross-disciplinary workflow are outlined.
Finally, suggestions are made on how to improve the functionality and efficiency of the algorithm. The primary conclusion made is to expand the criteria based on which a voussoir is selected for placement. An emphasis is directed towards using criteria such as distance-to-staggering, local radius of curvature, local force flow, and dimensions of the surrounding voussoirs to limit the offcuts that will be created to ensure complete tessellation.
Overall, this study provides a workflow that is enabled by a stacking algorithm. It outlines how to design double-curved, compression-only structures and how their design can influence the entire workflow. ...

Waste and robots
An opportunity for the future of carbon neutral buildings
In an effort to reduce the amount of construction and demolition waste (CDW) derived from the future generation of buildings, innovation and technologies are necessary. In the past several decades, robotic applications have made a great impact in many industries. Thanks to its efficiency, automated processes and flexibility of use, robotics has proven to be successful in manufacturing and assembly processes which can now be customized for architectural practices like the digital fabrication of new structures with the potential of implementation of new materials . If robotic manufacturing has the potential of upcycling CDW in the construction process, then buildings can have a smaller environmental footprint. Further research into experimenting with this waste material implemented into 3D printing with a 6DOF robot arm is necessary.

A Building system for the future
Architectural Engineering Graduation Studio
The booklet, paper and posters present the results of an innovative building system that can contribute to the sustainability of the construction sector. This concept was developed based on six months of research in which nine timber building systems were tested for their degree of flexibility and demountability. A framework was then created, where a chosen system was further developed, step by step, into a building concept that can be applied on a large scale. An attempt was made to incorporate every aspect that a building must satisfy without compromising simplicity. The development of the system has a generic and an applied phase. In the generic phase, the basis of the system is laid, which in theory is the same for every building. In the applied phase, the system is further ela¬borated based on the design assignment, which in this case concerns a temporary student building that must be transformed into laboratory and office functions after 10 years. Although the two phases are separate, the gaps in the generic part become vi¬sible when the system is tested in an actual design, resulting in a generic and specific phases that have continuous exchange and influence on each other. In practice, such a standardised system that is to be applied on a large scale is further fine-tuned after it has been realised and experimented with many times.

The Future Of Making
From projects to products
Established industrial manufacturing methods combined with parametric design have the potential to disrupt the conventional design-to-manufacturing processes in the building industry. Currently factors such as increasing cost of labor, stagnated productivity per employee and highly fragmented design-to-manufacturing processes in the building industry have not proved to be fruitful influences for the mass production of customizable buildings. Moreover, in order to become sustainable the building industry has to make a drastic shift towards renewable materials and integrate a high level of modularity.
With market fit solutions by product thinking a wide variety of parametrically engineered housing options can be offered to the customer without having to enter the entire iterative process of design and engineering. This strategy also allows to finally integrate a high level of robotization in off-site manufacturing facilities. ...

anchoring the design process
A framework to make the designerly way of thinking explicit in architectural design education
The five elements enable teachers and students to address the designerly attitude. The way designers reason consist of: (1) experimentation; an experimentation-based way of thinking; how to explore and reflect, (2) the frame of reference; a knowledge-based way of thinking; how to work with common and proven ‘professional’ knowledge, and (3) the guiding theme; a value-based way of thinking; how to take a position in the design process. Next to that, (4) the laboratory is the (visual) language or set of means designers use to think designerly, and (5) the domains are the playing field of the designer, the product aspects s/he should address. ...

De Beursgebouw has been empty for around 10 years since economic crisis in 2008. Because it was one of the city growth witness, citizens of Almere share a common memory of it, especially about its unique façade form, iconic big metal machine on the roof and the unusual ramps and stairs at entrance. In my case, the building, together with its neighbor abandoned office building on the north, are transferred into an amateur art center as a citizen gathering place with creative entertaining and catering venue. ...

Beursgebouw as social platform
Re-interpreting communal spirit of Beursgebouw
Based on findings of preliminary research and analysis, I started thinking about my own design assignment, and my focus point turned to the social value and communal spirit of the Beursgebouw. My ambition for the renovation is to make a new social platform where people from different generations and different groups come together and interact with each other, thus benefitting the Beursgebouw as well as the Almere city. ...

Recreatieve ecologie
Verbetering van de ruimtelijke kwaliteit door een samensmelting van recreatieve en ecologische belangen voor het Amsterdamse stadsmeer Nieuwe Meer
In deze thesis ligt de aandacht voor duurzame stedelijke ontwikkeling op de samenkomst van sociale, ecologische, economische en projectmatige belangen, ook wel verwoord als People, Planet, Prosperity en Project. Het doel van deze thesis is om het fysieke landschap van de Nieuwe Meer in Amsterdam aan te passen aan de belangen van verschillende actoren op duurzame wijze, en om op die manier toegevoegde waarde te creëren op het gebied van sociologie, ecologie, economie en het project. Daarom is deze thesis gericht op het beantwoorden van de volgende vraag: Hoe kan de People-Planet-Prosperity-Project (PPPP) methode toegevoegde waarde creëren voor de fusie van recreatie en ecologie in de Nieuwe Meer in Amsterdam?
Om een antwoord te kunnen geven op de onderzoeksvraag is een theoretische basis gevormd van het begrip ruimtelijke kwaliteit, de People-Planet-Prosperity-Project methode, en de Fusie van Belangenstrategie. Vanuit dit perspectief zijn vervolgens twee case studie-projecten geanalyseerd, resulterend in praktische inzichten in duurzame ontwerpstrategieën en generieke lessen voor een gelijksoortige ontwerpopgave. Om inzicht te winnen in de belangen en wensen van de stakeholders van de Nieuwe Meer is kwalitatief onderzoek uitgevoerd in de vorm van literatuuronderzoek, mondelinge individuele interviews en een online enquête. Het resultaat van het onderzoek bestaat uit een ambitiekaart voor de Nieuwe Meer waarin al deze belangen zijn samengevoegd en gevisualiseerd. Aan de hand van deze ambitiekaart is gezocht naar oplossingen voor een fusie van de ogenschijnlijk tegenstrijdige belangen en plannen, welke vorm hebben gekregen in een projectvoorstel voor een duurzame wakeboardbaan met bijbehorende landschappelijke elementen en horecavoorzieningen, als recreatieve impuls voor de Nieuwe Meer. ...

The Mass-Customisation of Urban Housing
User-Involvement in Housing Development
A possible solution, responding to the diverse demand, would be to involve the consumers themselves in the development of their dwelling. When involved, consumers can directly shape the dwelling to their needs themselves; customisation. However, current practices make this an undoable matter. The over-complexity in (pre)construction processes and conservative mind-sets of real-estate developers and construction firms hinder any level of participation with the consumer. There is a need for smart processes and designs to involve the user in the realisation of the customised urban dwelling. ...
