Procedural Passport: A Framework for Circularity in Buildings

Circularity is an emerging topic in sustainability that considers how waste can be reduced through design, across multiple life cycles. It uses the goals of recycle, reuse and remanufacture to capture value in materials and products at the end of their use-life. Achieving material and component circularity with buildings has been identified as a design issue that involves the application of three circularity principles which are: adaptability, disassembly and reusability. Buildings are typically unable to achieve material circularity because these three principles are not considered in their design, thereby causing their construction methods to rely on chemical bonds and permanent connections that make it difficult to separate materials at a building’s end-of-life.   The broader aim of this research is to develop a Procedural Passport (PP) framework that synthesizes relationships between digital design tools, design processes, construction techniques and contract roles, to implement circularity principles in buildings. However, two components of the procedural passport define the scope of this research; firstly, the implementation of the three circularity principles are explored as design processes through three key areas– design for deconstruction (DFD), design for reusability (DFR) and design for adaptability (DFA). Various means of optimizing the design processes are then explored through the application of digital tools. The construction techniques and contract roles component of the procedural passport are discussed as future areas for development.
