Title: Green Roofs
Abstract: Another alternative to traditional roofing materials is a rooftop garden, or "green roof." On hot summer days, the surface temperature of a vegetated rooftop can be cooler than the air temperature, whereas the surface of a traditional rooftop can be up to 90°F (50°C) warmer. This site examines the benefits, explains how they mitigate storm water runoff, discusses types and provides some examples.
