This book reflects and expands on current trends in the Architecture, Engineering and Construction (AEC) industries as they respond to the unfolding climate and biodiversity crisis. Shifting away from the traditional focuses, which are narrowly centered on efficiency, this book presents a variety of approaches to move the AEC community from a linear, extractive paradigm to circular and regenerative one. The book presents contributions including research papers and case studies, providing a comprehensive overview of the field as well as perspectives from related disciplines, such as computer science, biology and material science.
