| Abstract | Over the past decades computational design, digital fabrication and optimisation have become widely adapted in architectural research, contemporary practice as well as in the construction industry. Nevertheless, current design and fabrication process-chains are still stuck in a linear notion of material use: building components are digitally designed, engineered, and ultimately materialised by consumption of raw materials. These can be defined as digital-real process chains. But these parametric design logics based onmass customisation inhibit the reuse of building components. In contrast to these predominant and established digital-real process chains, we propose a real-digital process chain: departing from our real, already materialised built environment. We digitise and catalogue physical concrete components within a component repository for future reuse. Subsequently, these components are reconditioned, enhanced if necessary and transitioned into a modular building system. The modularised components are then recombined to form a new building design and, eventually, a new building by combinatorial optimisation using mixed-integer linear programming (MILP). An accompanying life cycle assessment (LCA) complements the process and quantifies the environmental potential of reused building components. The paper presents research towards a feasible workflow for the reuse of structural concrete components. Furthermore, we suggest a digital repository, storing geometric as well as complementary data on the origin, history, and performances of the components to be reused. Here, we identify core data to be integrated in such a component repository. |
