CO-DESIGN, ADAPTATION, INTEGRATION AND OPTIMIZATION OF MULTI-STOREY TIMBER BUILDING SYSTEMS FOR BUILDING STOCK EXTENSION

The fulfilment of the sustainable development goals defined by the United Nations requires innovations and commitments from all industries. For the building sector this translates into the need to adopt more cost- and energy-efficient methods, decrease material waste, and increase the use of CO2-neutral materials such as timber. This can be realised by developing co-design methods which integrate architectural, structural, and building physics criteria in feedback with novel fabrication and construction possibilities in order to articulate timber building systems that overcome the typical limitations of multi-storey timber structures. Such quasi mono-material and future-proof wood building systems are based on standard timber-materials (e.g. GLT or CLT) and offer open-purpose, multi-functional, and geometrically bespoke column, wall, and ceiling elements, thus achieving bi-axial, variable span, and structurally optimized, resource-effective solutions using on-site/ off-site additive and subtractive manufacturing processes. This would enable independence from typically restraining rigid grid ordering systems and foster new timber architecture typologies that are also attractive for long-term use by being adaptable and flexibly programmable.

Based on the insights of the predecessor project RP3-1, RP3-2 will address the next set of research challenges for the co-design methods and multi-storey timber building systems developments by: (1) Expanding the system’s design space towards the extension of existing building stock, through the investigation and integration of design adaptation methods and flexible strategies for establishing performative interfaces with existing structures. Further, (2) we will investigate the possibilities of replacing remaining non-timber building system elements with wood-based solutions, aiding in the integration of additional building elements into the existing building system, such as lateral bracing. Consequently, this will include the investigation of bonded joints in regard to energy dissipation capabilities and fire/high temperature resistance. We will also (3) extend the interdisciplinary modelling methods with further relevant parameters (e.g. fire-resistance) and investigate multi-parameter optimization methods and frameworks for the design beyond those developed in RP3-1. Finally, (4) the research will establish a coordinated interdisciplinary project development process and a coherent computational design and engineering model through continuous synthesis. The resulting novel building system and methods will be demonstrated and evaluated through the building elements in the IntCDC demonstrator building. In parallel, we will evaluate the building stock extension method through benchmark and synthesis studies.
