Cool Roofs Savings Calculators

A cool roof is a way of reducing the costs associated with air conditioning and this reduces energy usage which in turn reduces emissions. Estimates for cost savings associated with cool roofs run between 10 and 25 percent. There are a number of tools to help people evaluate the cost savings resulting from the installation of cools roofs. Below you will find two such tools, one from the US Department of Energy's Oak Ridge National Laboratory deals and the other developed by Oak Ridge National Laboratory and Lawrence Berkeley National Laboratory.

1. 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.

2. 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.
