The National Roofing Contractors Association updated its EnergyWise Roof Calculator.
The online tool now includes information from the 2015 version of the International Code Council’s International Green Construction Code and the 2013 version of ASHRAE Standard 90.1 (“Energy Standard for Buildings Except Low-Rise Residential Buildings”). The tool offers the following benefits:
- Judges compliances of the roof in the context of the codes and regulations for a given municipality
- Estimates the R-value for the materials and insulation selected
- Assesses the thermal gradient of the roof
- Provides a rough estimate of heating and cooling costs based solely on the roof infrastructure
According to the NRCA, about 3,700 contractors and others have registered to use the calculator.
