Penn State measured a green roof during a June 2002 heat spell; its membrane peaked near 30C, while the uncovered roof surface climbed to nearly 70C

Green roofs present a remarkable solution for enhancing temperature control in urban environments, effectively lowering surface temperatures. The vegetation on rooftops generates shade while aiding in air cooling through the process of evapotranspiration. This natural cooling not only alleviates indoor temperatures but also minimizes energy consumption. Across the country, federal agencies are increasingly adopting green roof systems, marking a strategic approach to mitigate summer cooling demands.
