πΏ Green roofs slash rooftop heat by 40Β°F
Scientists found green roofs significantly lower rooftop temperatures by utilizing natural cooling processes. These living roofs, which include layers like waterproofing and growth medium, are being adopted globally to combat rising urban heat. Measurements showed planted roofs were 30-40Β°F cooler than conventional roofs in sunny weather conditions. The cooling effect comes from vegetation shading and the evaporation of water from the soil. Cities can benefit from this as it lessens the need for internal cooling and supports wildlife.
