This book examines the way project teams can approach the design and expression of both active and passive thermal environmental control systems in a more creative way. Using case studies from around the world and interviews with architects and environmental engineers involved, the book illustrates innovative responses to client, site and user requirements, focusing on elegant solutions to a perennial problem. Architects will be inspired to take a more creative approach to the design and expression of environmental control systems - whether active or passive or whether they influence overall building form or design detail. Each featured project includes information on the designers; project background and the design process; design outcome and thermal environmental control systems; expression of thermal environmental control systems; and performance in practice and lessons learned.
