To compare how much energy is required by a building with a green roof with buildings that have dark roofs or white (reflective) roofs, check out the Green Roof Energy Calculator from Arizona State University. More specifically, they work best when there is less than 20 to 30 degrees of slope [2]. The benefits include increased energy efficiency (from cooling in the summer and added insulation in the winter), longer roof membrane life span, sound insulation and the ability to turn wasted roof space into various types of amenity space for building occupants. Green spaces show a longer residence time. Green Roof Benefits: Extends roof membrane life by 2.5 to 3 times longer than typical waterproofing Detains stormwater Reduces the Urban Heat Island Effect Lowers cooling costs Cleans air Increases habitat and biodiversity Protects from hail damage Creates urban food production Improves aesthetics Expand roof life 2x3 times (up to 60 years) Reduce air-conditioning costs. Also, because green roofs help to moderate the temperature of both buildings and of the overall urban area, there is reduced energy demand, and therefore helps to reduce the overall amount of pollutants generated by power plants, including greenhouse gas emissions.
