Peak energy demand has become a hot topic in the world of roofing. A sharp peak in electrical demand can be observed in nearly every building during the busiest hours of the day. In fact, peak demand charges may account for a significant portion of monthly electric bills across America.

One of the best approaches to minimize peak demand is to reduce the heat load on the building, especially the solar load that drives the need for air conditioning. Few heat-reduction strategies can match the energy-saving potential of modern cool roofing technology.
