Book excerpt: For the first time, this book demonstrates that the two paradigms of architectural criticism and performance evaluation can not only co-exist but complement each other in the assessment of built works. As architecture takes more principled stances worldwide, from environmental sustainability to social, cultural, and economic activism, this book examines the roles of perceived and measured quality in architecture. By exploring in tandem both subjective traditional architectural criticism and environmental design and performance evaluation and its objective evaluation criteria, the book argues that both methodologies and outcomes can achieve a comprehensive assessment of quality in architecture. Curated by a global editorial team, the book includes: Contributions from international architects and critics based in the UK, USA, Brazil, France, Qatar, Egypt, New Zealand, China, Japan and Germany Global case studies which illustrate both perspectives addressed by the book and comparative analyses of the findings A six part organization which includes introductions and conclusions from the editors, to help guide the reader and further illuminate the contributions. By presenting a systematic approach to assessing building performance, design professionals will learn how to improve building design and performance with major stakeholders in mind, especially end users/occupants.
