The Thermal Advantage of a Green Roof
A green roof absorbs a significant portion of rainwater and retains it temporarily. This water is then gradually released into the atmosphere by the plants through the process of evapotranspiration. This natural cooling effect plays a vital role in mitigating urban heat islands, especially in dense downtown areas. The system also enhances urban aesthetics and contributes to local biodiversity.
