Abstract
As part the new RoofPoint rating program for sustainable roofing systems, the Research Committee of the Center for Environmental Innovation in Roofing (CEIR) developed a unique multi-factor approach to the selection of sustainable roof surfaces. As a foundation for evaluation, RoofPoint identifies different outcomes related to the thermal characteristics of roof surfaces. In almost all cases net energy savings is an important outcome, and in many areas of the country the type of roof surface makes a significant contribution in reducing total building heating and cooling costs. In other areas, peak energy savings also may be an important outcome, especially in localities with seasonal demand charges for the electricity needed to power air conditioning systems. Finally, reducing heat island effects may also be important, especially in dense urban areas.
