Book excerpt: This book relates circular economy principles to housing design and construction and highlights how those principles can result in both monetary savings, positive environmental impact, and socio-ecological change. Chapters focus on three key circular economy principles and apply them to architectural construction and design, namely rethinking of the end-of-use phase of a building and the potential of design-for-disassembly; the role of digitization and data standardization in fostering evidence-based circular economy design decision-making; and presenting space as a resource to conserve, via exploration of the sharing economy and flexibility principles. Beyond waste management and material cycles, this book provides a holistic understanding of the opportunities across the building life cycle that can allow for sustainable and affordable circular housing. With case studies from 13 different countries, including but not limited to the Hammarby Sjöstad district in Sweden, the Circle House in Denmark, Benny Farm in Canada, VMD Prefabricated House in Mexico, and the Deep Performance Dwelling in China, authors pair theoretical frameworks with real-world examples. This will be a useful resource for upper-level students and academics of architecture, construction, and planning, especially those studying and researching housing design, building technology, green project management, and environmental design.
