Facades determine the appearance of a building. Thus they have a very important role to play in architecture. At the same time, the building envelope has important functions to fulfill, including lighting, weatherproofing, thermal isolation, load distribution, and sound insulation, to name only the most important. In the last fifteen years, facades have become significantly more complex. For example, intelligent, climate-active facades use self-regulating systems to respond to changing light and weather conditions. This book demonstrates the principles of facade construction. Guidelines are suggested for good detailing. The installation procedures are described for the most common materials -glass, wood, steel, concrete, and aluminum. Numerous drawings made specially for the book explain the principles of the individual types of facade which are then illustrated with built examples.
