Savings Calculators
Calculating cost savings resulting from the use of cool roofs can be done using several tools developed by federal agencies.
- DOE Cool Roof Calculator
This tool developed by U.S. Department of Energy's Oak Ridge National Laboratory estimates cooling and heating savings for low slope roof applications with non-black surfaces.
- Roofing Comparison Calculator (RSC)
This tool was developed by Oak Ridge National Laboratory and Lawrence Berkeley National Laboratory in order to provide industry-consensus roof savings for both residential and commercial buildings. It reports the net annual energy savings (cooling energy savings minus heating penalties) and thus is only applicable to the buildings with a heating and/or cooling system.

Famous quotes containing the word calculators:
“But the age of chivalry is gone. That of sophisters, economists, and calculators has succeeded; and the glory of Europe is extinguished forever.”
