In The Philosophy of Sustainable Design, McLennan outlines the major ideas and issues that have emerged in the growing movement of green architecture and sustainable design over the last thirty years. The book is rooted in practical knowledge but rather than being a ‘how to book’ asks individuals to understand how the philosophy of sustainable design can affect their own work. Part Sustainable Design 101 and part manifesto this book lays the groundwork and philosophical basis for more technical study. McLennan relies on his extensive experience with sustainable design having consulted to dozens of projects and design teams all over the country. Tapping into the work of many pioneers and ‘green design philosophers’ McLennan clearly presents a framework for practitioners and students to understand sustainable design and how ultimately it will become the future of architecture and design.
