For roofing materials, the Energy Star program has been available since early 1999. Energy Star focuses exclusively on the solar reflectance of materials, including both initial values and values obtained following three years of weathering. Cool Roof Rating Council (CRRC) was established with a commission to set up a fair rating system for the radiative properties of roofing materials. The CRRC system establishes a system to collect credible radiative data and maintains a directory of rated products with their rated properties. Manufacturers cannot 'self-report' performance values. Under the CRRC requirements 'aged' values are determined by examining exposure data generated at three designated 'test farms' representing hot/humid, hot/dry, and 'Midwestern' exposure conditions. The roofing market is a USD 10+ billion market, and many opportunities exist for coatings to contribute to the success of this market with regard to energy conservation.
