Abstract
Low slope roofs on commercial buildings are directly exposed to the maximum amount of solar radiation. The solar radiation that is absorbed heats the roof surface. The absorbed solar energy, now characterized by the roof surface temperature, is partially re-emitted in the infrared spectrum. Selecting or coating a low slope roof so it has a medium to high solar reflectance and a low to high infrared emittance achieves the desired amount of solar radiation control. In this paper, background information is presented on the development of an interactive estimating tool to assist commercial building owners and/or operators in the selection of a roof.
