This collection of ecological evaluations and data on structural physics is a classic in every design library. Planners, architects, and clients will find a wealth of reliable construction details on matters such as passive house standards, building materials, the criteria for verifying ecologically optimized planning, and tendering in the fifth edition of this catalog. New features include information on the circularity of components, and QR codes that enable direct access to the online database Baubook. All assessments are based on international passive house standards. This is a meticulously researched reference work which, thanks to its bilingualism, overcomes language barriers and is therefore an invaluable aid in consultations with international clients.
