Studies Show Green Roofs, Cool Pavements, and Reflective Roofs Reduce Urban Heat
Research from multiple U.S. cities shows that green roofs, cool pavements, and reflective roofing materials can significantly reduce surface temperatures and lower cooling energy demands. Studies in St. Paul, Irvine, and Merritt Island found temperature reductions ranging from 7 to 60 degrees Fahrenheit, leading to decreased urban heat and energy costs. These strategies address rising urban temperatures and heat-related health risks by mitigating heat absorption in buildings and streets through vegetation, reflective coatings, and lighter materials.
