The Chair of Geoinformatics, in cooperation with the Leibnitz Institute for Ecological and Regional Development (IöR) and Fraunhofer ISE, has determined the theoretical area potential of building facades throughout Germany. At 12,000 square kilometres, it is twice as large as the area potential of roofs. The figures are still theoretical and more detailed, small-scale investigations with precise input data are still pending. Nevertheless, the results are a first step towards better planning of the energy transition in buildings. Here you can find the complete press release of the IöR with further details.
This radio report in the science program Quarks on WDR also addressed the topic.
