Analyse des PV-Potenzials von Wohngebäuden anhand siedlungsgenetischer Merkmale

This study analyzes the solar potential on roofs of residential buildings in the city of Hamburg as a function of the city's settlement genetic characteristics. Hamburg's solar cadaster is critically evaluated with regard to rooftops, building, and settlement types as well as building orientation. Based on building ground plans, building and settlement types are calculated using geometric and geographic information systems (GIS) based methods. The set of data thus generated, along with further information on a Region's stock of buildings, allows the determination of its PV potential. This method is more accurate than previous estimations based solely on statistical information on the building stock.
