Green Stormwater Management

Green detention roofs are established on-site stormwater management tools, leading to fewer additional space-constraining and costly at-grade structures, as well as fewer sealed areas.

Due to the changing climate, storm intensities are forecasted to increase over the coming years in Germany, and elsewhere around the globe. Thus, today's building solutions must be adapted to the future world conditions to ensure resilient properties.

There are technical reasons why green stormwater management on the roof should be considered in the design. But there are many other reasons for this investment. Among others, one reason is the reputation of a landlord, especially regarding larger projects or city plans. Since green water management is becoming a standard, it should be considered in sustainability planning. Already now, municipalities have agreed on the green roofs as tools for stormwater management in their zoning plans, as part of a conceptional sustainability strategy.

The combination of photovoltaic and green roof stormwater management should be the standard on larger roof areas, whether logistic center, office building, or residential buildings.
