How Green Roofs Could Save Lives - EcoBuilding Pulse
In addition to adding parkland and community gardens, great opportunities for increasing urban green space without new real estate lie on unused roofs. While some roofs cannot accommodate the weight of a green roof with dirt and vegetation, coupling initiatives to incorporate both green roofs and cool roofs via a reflective coating could lower the temperature of a neighborhood by a few degrees Fahrenheit and reduce building temperatures by up to 30 percent . This not only improves public health by reducing heat-related mortality, but it also reduces reliance on air conditioners and traditional energy use for cooling therefore reducing greenhouse gas emissions. Not to mention it adds a way for city-dwellers to experience the great outdoors.
