Initial Results

Evaporation of water is an economic and effective means for the air conditioning of a building. The evapotranspiration of one cubic meter of water produces an evaporative cooling with a value of 680 kWh. Adiabatic cooling systems can practically be seen as substitutes for conventional air conditioning technologies. Synergies can also be achieved by using rainwater in decentralised systems, for example rainwater can be used for both irrigation and adiabatic cooling.

Greening a building’s roof and façades, one of the passive cooling systems, results in significant additional evapotranspiration. It has a high potential of reducing the building’s surface temperatures thereby improving the microclimate inside and around the building.
