Circular Construction for urban development is based on the Circular Economy theory developed by the Ellen McArthur Foundation.  The perspective presented is how circular principles can be implemented on multiple levels in the building industry by applying off-site modular industrialised construction.  The book’s overarching theme is exploring the synergies of coupling circularity with industrialisation. The construction sector is well known for being siloed and slow to innovate due to its inherent nature of starting over in each individual project and solving the same challenges with new teams and new solutions. Through industrialised construction, our current project-focused practice can be turned into circular product platform thinking based on the belief that rationalisation and technological innovation will continue to play a significant role in shaping a safer and fairer future. This book introduces various principles, perspectives, and tools. It covers principles of design for disassembly, material and building passports, and circular business models. It also provides perspectives on circular life cycle assessment and tools that can provide circularity insights, planetary boundary targets for construction, and estimates of existing reuse and upfront carbon savings.
