This book offers an innovative and highly practical approach to architectural design. Focusing on the concept of performance that brought about a paradigm shift in the humanities in earlier decades, the book discusses how to use this concept to address ongoing problems in architecture. It explores the meaning of performance in the context of the built environment, design processes, sustainable architecture, spatial organization, and other aspects of design. Featuring numerous color illustrations plus historical and contemporary examples, this is an eye-opening resource for architects and urban designers.
