It is considered that the dark surfaces of buildings and pavements are of the major heat sources causing the urban heat island phenomenon.
Pavements and Roofs account a significant percentage of the land surface in an urban area.
Cool pavements and Cool Roofs can mitigate the urban heat island effect.
Cool Roofs and Cool Pavements have high solar reflectance (high ability to reflect sun-light) and high thermal emittance (high ability to radiate heat) and stay cool in the sun.
Energy savings from installing a Cool Roofing Product depends on the local climate, existing insulation levels, the type of roof replaced, the type of roof installed, and maintenance. In the best applications, cool roofs have no incremental cost and deliver a nearly instant payback.
