Abstract/Contents:This presentation is expected to be an argumentative basis for a better acceptance of roof planting based on measurements made with green roofs. The experiments show that annual evaporation factors of 45% - 70% of the rainfalls can be achieved. When choosing ideal substrates an essential reduction of the peak runoff is registered. Depending on the rating of rainfalls with 100, 200 and 300 1/(s*ha) reductions of the peak runoff as much as 52%, 29% and 17% could be registered when using efficient substrates. The runoff coefficient declines with increasing watercourse. Considering a watercourse of 10,0 m single-stratum construction techniques show a 45% better runoff coefficient than multi-strata construction techniques.
