Extensive sedum-covered green roofs increase the air temperature during the day and exhibit weak cooling effect at night. The effect of a different initial soil moisture contents showed a tipping point around 0.12 m3m−3. Under an extremely dry conditions, a nocturnal cooling effect is no longer apparent above the green roof. Measurements 30 cm above roof level are influenced more by the surrounding area than by the properties of the roof surface.
