The Design-to-Robotic-Production and -Assembly (D2RP&A) process developed at Delft University of Technology (DUT) has been scaled up to building size by prototyping of-site a 3.30 m high fragment of a larger spaceframe structure The fragment consists of wooden linear elements connected to a polymer node printed at 3D Robot Printing and panels robotically milled at Amsterdam University of Applied Science (AUAS). It has been evaluated for suitability for assembly on-site without temporary support while relying on human-robot collaboration. The constructed architectural hybrid structure is proof of concept for an on- and off-site D2RP&A approach that is envisioned to be implemented using a range of robots able to possibly address all phases of construction in the future.
There is an increasing call in society for the improvement of well-being for nursing home residents and the support of care professionals through a wide array of architectural and technological solutions that are available in modern nursing homes. This study investigated which of these solutions are considered essential by stakeholders from healthcare and technology. Data were gathered via 22 simultaneously held multidisciplinary mind map sessions with 97 stakeholders, resulting in 43 mind maps. These, in turn, were grouped into a single mind map of the nursing home in general, the private rooms for residents with somatic or psychogeriatric health problems, and the group living room. A prioritization of solutions was added. The contents of the mind maps reflect a Dutch consensus on the necessary architectural and technological features for the design of nursing homes.
Designing cities that are socially sustainable has been a significant challenge until today. Lately, European Commission’s research agenda of Industy 5.0 has prioritised a sustainable, human-centric and resilient development over merely pursuing efficiency and productivity in societal transitions. The focus has been on searching for sustainable solutions to societal challenges, engaging part of the design industry. In architecture and urban design, whose common goal is to create a condition for human life, much effort was put into elevating the engineering process of physical space, making it more efficient. However, the natural process of social evolution has not been given priority in urban and architectural research on sustainable design. STEPS stems from the common interest of the project partners in accessible, diverse, and progressive public spaces, which is vital to socially sustainable urban development. The primary challenge lies in how to synthesise the standardised sustainable design techniques with unique social values of public space, propelling a transition from technical sustainability to social sustainability. Although a large number of social-oriented studies in urban design have been published in the academic domain, principles and guidelines that can be applied to practice are large missing. How can we generate operative principles guiding public space analysis and design to explore and achieve the social condition of sustainability, developing transferable ways of utilising research knowledge in design? STEPS will develop a design catalogue with operative principles guiding public space analysis and design. This will help designers apply cross-domain knowledge of social sustainability in practice.
In 2017, renowned Prof Kate Raworth from Oxford University and Amsterdam University introduced Doughnut Economics, an economic model to enable humans to thrive within the planetary boundaries and resources. Several private and public actors, including the city of Amsterdam, adopted the model in their circular economy development's strategies. Doughnut-Architecture aims to develop further the AREA (Atelier for Resilient Environmental Architecture) Framework, a tool designed by graduating students Charlotte Uiterwaal, Isabella van der Griend, Ryan McGaffney, Karolina Bäckman, at the faculty of Architecture, Delft University of Technology (TU-Delft), under the supervision of Henri van Bennekom. AREA-Framework support architects to intervene in the built environment taking as a reference the Doughnut Economics model. The AREA-Framework is at an initial stage, and its categories and subcategories are only qualitative. TU-Delft, the architectural practices Space&Matter and SuperuseStudios, in collaboration with the interdepartmental research group Circular Built Environment Hub (CBEH) and architectural practices from the network of 400 construction companies belonging to the Ex'tax project, the advice from Kate Raworth and the Amsterdam-Donut-Coalitie will further develop the AREA-Framework primarily quantitatively and also qualitatively. TU-Delft, Space&Matter, SuperuseStudios, other architectural practices from the Ex'tax-network will test the framework on different phases of real projects, interdepartmental research and education. The ultimate goal is to develop the framework further, to increase the number of architectural practices successfully implementing the Doughnut Economics in the built environment at a national level. The framework will contribute to positioning the architectural practices concerning Doughnut Economics and the Circular Economy. The project results are firstly an online open-access publication about the further developed Framework to be applied by architects; secondly, the preparation and submission of a follow-up research proposal about the extended development and implementation of the Framework applicable to the built environment by all the Ex'tax construction sector companies.
In the past decade additive manufacturing has gained an incredible traction in the construction industry. The field of 3D concrete printing (3DCP) has advanced significantly, leading to commercially viable housing projects. The use of concrete represents a challenge because of its environmental impact and CO2 footprint. Due to its material properties, structural capacity and ability to take on complex geometries with relative ease, concrete is and will remain for the foreseeable future a key construction material. The framework required for casting concrete, in particular non-orthogonal geometries, is in itself wasteful, not reusable, contributing to its negative environmental impact. Non-standard, complex geometries generally require the use of moulds and subsystems to be produced, leading to wasteful, material-intense manufacturing processes, with high carbon footprints. This research proposal bypasses the use of wasteful scaffolding and moulds, by exploring 3D printing with concrete on reusable substructures made of sand, clay or aggregate. Optimised material depositing strategies for 3DCP will be explored, by making use of algorithmic structural optimisation. This way, material is deposited only where structurally needed, allowing for further reduction of raw-material use. This collaboration between Neutelings Riedijk Architects, Vertico and the Architectural Design and Engineering Chair of the TU Eindhoven, investigates full-scale additive manufacturing of spatially complex 3D-concrete printed components using multi-material support systems (clay, sand and aggregates). These materials can be easily shaped multiple times into substrates with complex geometries, without generating material waste. The 3D concrete printed full-scale prototypes can be used as lightweight façade elements, screens or spatial dividers. To generate waterproof components, the cavities of the extruded lattices can be filled up with lightweight clay or cement. This process allows for the exploration of new aesthetic, creative and circular possibilities, complex geometries and new material expressions in architecture and construction, while reducing raw-material use and waste.
