"Understanding Sustainable Architecture" is a concise review of the assumptions, beliefs, goals and bodies of knowledge that underlie the endeavor to design environmentally sustainable buildings and other built environments. The authors set out a coherent framework within which they discuss the important ethical, cultural, and conceptual issues of sustainable architecture. Through a series of self-reflective questions, the importance of ecological, social, and built contexts is argued, and problem framing is linked to succesful practice.
