Remote Sensing - Green Roof Inventory and Potential Analysis

Abstract

Green Roofs can help to adapt cities for climate change, through the provision of cooler microclimates and reduced stormwater run-off. They also enhance biodiversity in urban ecosystems. In order to evaluate these positive effects in a quantitative way, information about the already existing Green Roofs and potential Green Roof sites is needed. In a current research project the German Aerospace Center (DLR), the German Roof Gardener Association (Deutscher Dachgaertner Verband) and different German partner cities developed a method with which already existing Green Roofs and potential roof areas can be identified and inventoried from a "birds-eye view". The new database can make a valuable contribution to the application of Green Roofs in sustainable urban planning.
