ENERGY SAVING CALCULATORS
How can you get a quantitative analysis of the potential energy savings for your building without performing a detailed building energy simulation? Simple web-based tools developed by federal agencies can help architects, specifiers, roofing contractors, building owners or facility managers assign an estimated value on the annual energy savings that can accrue during the life of a typical white reflective roof vs. a non-reflective black roof.
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.
