Potential of roof top PV-systems for supplying electricity in residential area Scharnhauser Park

This study is a part of a large scale urban development project called POLYCITY dealing with how to make cities more energy efficient. The project is already in progress in three different countries like Italy, Spain and Germany. We will keep our analysis focused only on German part Scharnhauser Park, which is located in Stuttgart. In this project the working and living places are integrated in order to get a sustainable city quarter with special emphasis on minimum travel distance and low energy consumption. As renewable energies are an additional source to conventional ones, they are more and more important for the production of the energy. The interesting feature is that a great deal of the necessary energy will be provided from roof top PV-systems and wood fired cogeneration plants. Laser Scanning data along with GeoMedia are used for finding the potentials of roof top. The analysis is also supported with Web Application to disseminate the information to the public. This approach will set a good example for supplying green energy in residential quarters and will provide a basis for the sustainability of similar communities.
