Cool Roof Energy Savings Tool
Wayne, N.J.-based GAF's Cool Roof Energy Savings Tool (CREST) is a self-service roof energy calculator and rebate finder and is available for free. CREST helps to compare multiple cool roof designs, varying levels of reflectivity and insulation.
Although a user may set exact values as desired, CREST pre-populates the calculator with utility cost information based on the user's ZIP code; includes images of the job site from Google Earth; and automatically searches rebates to the ZIP code level, generating a proposal-quality report.
Currently, hundreds of users access the calculator every month to generate reports that include the ability to compare up to three proposed designs to the base design.
