Cooling Savings Calculator – Legal Disclaimer

Potential savings values are approximate and provided for general reference purposes only. Regional temperatures‚ energy costs‚ and emissions based on national averages published by the US Department of Energy and the US Environmental Protection Agency. Actual energy savings will vary depending on the HVAC system‚ average indoor/outdoor temperature‚ length of cooling season‚ geography‚ actual energy costs‚ and other factors. Data shown represents center of glass values in accordance to NFRC 100/200‚ and is measured on NFRC required glass types‚ actual performance will vary with specific glass type. Emission savings estimates are based on average CO2 emissions from electric power generation per region in the United States as determined by the United States Environmental Protection Agency as of July 2000. These savings estimates account for emission reductions resulting from potential decreased electricity usage for home cooling only; they do not account for CO2 emissions that may result from manufacturing processes.
