Kolb has been actively involved with the CRRC since he joined NCC six years ago. “The importance of having an entity such as the CRRC today cannot be overstated. Credible ratings are now available for high-reflectivity roof products tested by certified independent labs, thereby helping consumers and building authorities make decisions based on sound results provided and administered by third parties,” said Kolb.

 

While a cool roof may be defined differently by different codes or programs, in simple terms, a cool roof reflects and emits the sun's heat back to the sky instead of transferring it to the building below. "Coolness" is measured by two properties, solar reflectance and thermal emittance. Both properties are measured from 0 to 1; the higher the value, the "cooler" the roof.

 

The CRRC is an independent organization that has established a rating system for displaying accurate radiative property data on the outermost layer of roof surfaces. Many products rated with the CRRC may improve the energy efficiency of buildings while positively impacting our environment.
