ENERGY CALCULATORS
Calculating cost savings resulting from the use of cool roofs can be done using several tools developed by federal agencies.
U.S. Department of Energy (DOE) Cool Roof Calculator
This tool developed by DOE's Oak Ridge National Laboratory estimates cooling and heating savings for low slope roof applications with non-black surfaces.
ENERGY STAR® Roofing Comparison Calculator
This tool developed by the U.S. EPA calculates the net savings accruing from installing an ENERGY STAR® labeled roof product on an air conditioned building. In addition to cooling savings, the program considers any resulting differences in heating costs.
