Abstract des Vortrags:
Wetland roofs are irrigated green roofs for stormwater retention and for climatization of the floor below the roof. They can also be used for domestic greywater treatment. Stormwater or greywater is stored in a cistern and pumped in several intervals per day on top of the roof via an automatic irrigation controller. The water then supplements evapotranspiration losses in a water storage and plant carrier mat. Evapotranspiration by marsh plants and shadowing of the roof is providing the cooling effects both for the rooms under the roof and for the outside environment. Wetland roofs can be constructed either on tilted or flat roofs and do not have any mineral layers, thus consisting only of the planted textile mat.
