EnergyWise Roof Calculator Online has been updated

NRCA's EnergyWise Roof Calculator Online has been updated to include information from the 2012 version of the International Code Council's International Energy Conservation Code (IECC) and the 2012 version of the International Green Construction Code (IgCC). In addition, new minimum long-term thermal resistance values for polyisocyanurate insulation, effective Jan. 1, 2014, have been included in the application.

EnergyWise Roof Calculator Online is available for free on NRCA's website, www.nrca.net, and offers an interactive graphic method of constructing virtual roof assemblies to evaluate thermal efficiency. The application denotes minimum thermal insulation requirements established by ASHRAE Standard 90.1, ASHRAE Standard 189.1, IECC and IgCC.

EnergyWise Roof Calculator Online is a user-friendly application that prompts users to enter specific roof assembly information, such as roof area, climatic region, heating appliance type and cost, roof openings and roofing materials to be used. Users then can generate a report summarizing the proposed roof assembly design, estimated heating and cooling costs, and minimum thermal requirements.

Funding for the update was provided by The Roofing Industry Alliance for Progress. The Alliance serves as a collective forum of roofing contractors, manufacturers, suppliers and industry professionals who select and provide oversight of programs and funding for progressive research that contributes to the roofing industry's ongoing advancement.
