The completely revised basic work presents itself at the state of the art. The numerous explanations on sustainable building systems are brought together in the new chapter "Energy Concepts". The technical content is condensed according to the facts and contexts relevant to architects and civil engineers. The extensive illustration section with detailed drawings for pictorial commentary on the text has been revised and updated. The "Bean" thus remains an indispensable basic work for keeping pace with the dynamic technological development, the increasing demands for comfort and the requirements for an economical and environmentally friendly use of energy in technical building.
