Co-development of a Framework for Circular Building Adaptability in Adaptive Reuse: A Participatory Study

Abstract

Population growth, market volatility, building obsolescence and property vacancy are triggers for adaptive reuse. Thus, adaptive reuse is an investable practice that needs to be facilitated by the means of adaptable design. Furthermore, adaptive reuse aligns with the principles of circular economy (CE), as it promotes the reuse of buildings and their longevity; thereby, reducing the need for new materials. In this regard, promoting the so-called circular building adaptability (CBA) in adaptive reuse could provide different benefits to the built environment, including long-lasting functionality and material reversibility. However, no guiding tool has been developed yet to practically guide practitioners on how to promote CBA in adaptive reuse.  Therefore, this study aims to develop a guiding framework for CBA in adaptive reuse. First, a content-wise guiding framework was synthesized based on lessons learned from the relevant literature and case studies. The framework brings together a series of passive, active and operational strategies alongside their enabling and inhibiting factors. Second, a co-creation workshop was conducted and triangulated with three interviews to validate and expand the defined strategies. Based on the findings of this participatory approach, the developed framework encompasses 33 strategies. This framework can be seen as a legitimate and informative tool for practitioners, as it was constructed based on acquiring knowledge from theoretical research, empirical research and participatory research.
