Scientists in the Netherlands have assessed how the so-called blue-green roofs can help reduce the operating temperature of rooftop PV panels and have found they provide a significant cooling effect. The irrigation system used for the research project relies on an additional water supply sourced from grey water from showers that is transformed into irrigation water.A research group led by the Netherlands' Water Research Institute has investigated how a blue-green roof (BGR) may act as a cooling agent for rooftop PV systems and has found that this kind of roof may lower the roof surface temperature ...Den vollständigen Artikel lesen ...
