  • Abstract in English : Extensive and intensive roofs contribute to modern storm water management in various ways: overall reduction and delay of the rainwater run-off; storage of rainwater within the green roof build-up for the plants; transpiration of the stored water. A very important feature with regard to the water retention capacity of green roofs in Germany is the so-called “Abflussbeiwert” (run-off coefficient). This value represents the amount of water that cannot be stored within the green roof build up during a distinct rainfall. In this paper, the results of different experiments and the methodology of measuring wuith regards to the practical performance and its weak spots are presented.
