“Green roof technology is not new. In Europe green roofs have been applied successfully for more than 20 years. However, it has only recently been introduced into North America. Because of their many energy-saving and environmental benefits, green roofs are a promising technology for energy-efficient buildings. Green roofs significantly contribute to energy and water saving goals. By shadowing the surfaces of a roof, they reduce heat gain through it by nearly 100%. In addition, a green roof’s soil and vegetation layer absorbs and filters rain, preventing it from quickly becoming runoff from the roof’s surface. Green roof technology is an effective,practical way to increase the energy performance of buildings and limit storm water runoff.”
