Book excerpt: In this timely book, Emilio Jose Garcia and Brenda Vale explore what sustainability and resilience might mean when applied to the built environment. Conceived as a primer for students and professionals, it defines what the terms sustainability and resilience mean and how they are related to each other and to the design of the built environment. After discussion of the origins of the terms, these definitions are then compared and applied to case studies, including Whitehill and Bordon, UK, Tianjin Eco-city, China, and San Miguel de Tucuman, Argentina, which highlight the principles of both concepts. Essentially, the authors champion the case that sustainability in the built environment would benefit from a proper understanding of resilience.
