PRODUCT RATING PROGRAMS
ENERGY STAR®
ENERGY STAR® is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy designed to reduce greenhouse gas emissions and help businesses and consumers save money by making energy-efficient product choices.
For low slope roof applications, a roof product qualifying for the ENERGY STAR label under its Roof Products Program must have an initial solar reflectivity of at least 0.65, and weathered reflectance of at least 0.50, in accordance with EPA testing procedures.
Warranties for reflective roof products must be equal in all material respects to warranties offered by for comparable non-reflective roof products, either by a given company or relative to industry standards. For a qualified product list, go to:
www.energystar.gov
Cool Roof Rating Council (CRRC)
CRRC is the sponsor of a third-party testing and uniform rating program that provides credible reflectance and emissivity data on roof surfaces (including roofing membranes) for building code bodies, energy service providers, architects and specifiers, property owners and community planners.
Its rating program provides manufacturers and sellers with the opportunity to label roofing products according to measured initial and aged radiative properties. These properties are determined and verified through testing by both CRRC accredited laboratories and a process of random testing. The program does not specify minimum or goal values for any radiative property. A directory of all rated products is at: www.coolroofs.org
