Gestaltungspotenzial von Solarpaneelen als neue Bauelemente - Sonderaufgabe Baudenkmal

Building integration of photovoltaic (PV) systems in most cases leads to a “high tech” and “modern” appearance of the building. This is caused by the typical grid shaped surface of most conventional PV modules. Regarding however that 90% of the building stock consists of longer existing, that means “old fashioned” buildings, it is evident that an aesthetically satisfying building integration of PV needs a lot of good will and creativity from planners and architects. In many existing building integrated PV systems the modules contrast with the building and its surroundings. Basing on the fundamentals of function, technology, production and building rights the work concentrates on the design potential and the aesthetical influence of building integrated PV modules with a special focus on historical listed buildings. The assessment of PV roof systems, overhead glazing and façade elements demonstrates the state of the art of building integrated PV modules in historical listed buildings. This includes architectural design strategies as well as the conflicts in the aims of the different stake holders. Analogies with established building materials and elements show the (visionary) design potential of the new building element “PV module”. The aim of the work is to discuss and assess the potential for the integration of PV energy systems into existing buildings – also concerning requirements on innovative PV modules for better adaptation to the building skin. Special attention is paid to architectural and aesthetic questions.
