The Cool Roof Rating Council (CRRC) is an independent and non-biased organization that has established a system for providing Building Code Bodies, Energy Service Providers, Architects & Specifiers, Property Owners and Community Planners with accurate radiative property data on roof surfaces that may improve the energy efficiency of buildings while positively impacting our environment. This section explains the program functions.


  • Independent organization
  • Established a method for reporting creditable reflective properties of roof surfaces
  • Registers laboratories to do the testing
  • Maintains list of registered manufacturers and product reflective properties

Test Methods CRRC-1

Test Methods

  • Reflectivity
    • ASTM E 908
    • ASTM E 1918
    • ASTM C 1549
  • Emittance
    • ASTM C 1371

Test Procedures

  • Inital
    • Samples submitted to accredited laboratory for testing
