Abstract
NRCA has updated its EnergyWise Roof Calculator, a free online calculator that determines roof assemblies’ minimum thermal insulation requirements and energy usage costs for heating and cooling for specific low-slope roof assembly designs. The update incorporates the latest revisions to model energy codes and energy-efficiency standards. To date, nearly 6,300 registered users have input more than13,000 projects. With this new update, these numbers should increase significantly.
