Decentralised Rainwater Management

Transfer of rainwater from the cisterns

The building of the Institute of Physics is not connected to rainwater sewers. One of the main goals of the decentralised rainwater management is the retention of rainwater. Rainwater is stored in 5 cisterns in two courtyards of the building, and primarily used for the irrigation of the façade greening system and the adiabatic cooling. Storm water events with heavy rainfall are managed with an overflow to the pond in one of the courtyards, from which the water can evaporate or drain into the ground. To protect the ground water from pollution, this drainage is only allowed through surface areas with vegetation. Some of the roof surfaces are extensively greened.
