This on-demand course covers how solar-reflective “cool” roofs and walls address the impacts of heat and energy use; the properties that determine the “coolness” of a product; the factors that influence energy savings and performance; and the role of third-party product ratings in code and program compliance. This course also describes several third-party educational resources available online and at no charge to the public.
The standard covers test specimen preparation and test methods for measuring the initial and aged radiative properties of roofing products. The standard is referenced by building codes and rating programs worldwide in order to measure the initial and aged solar reflectance and thermal emittance of roofing products.
California’s Building Energy Efficiency Standards for Residential and Nonresidential Buildings (Title 24, Part 6) contains requirements for the thermal emittance, three-year aged reflectance, and Solar Reflectance Index (SRI) of roofing materials used in new construction and re-roofing projects.
The L.A. Green Building Code requires roofing material used in residential buildings meet minimum values for three-year aged solar reflectance and thermal emittance, or aged SRI.
