KSU Finds that Power*e™ Glass means Better Heat with Less Power
The National Gas Machinery Laboratory of Kansas State University is a leading independent organization regarding the advancement and testing of heating technologies. They tested the Power*e™ Glass windows in 2007 and 2008 to quantify their performance and capability to maintain a constant room temperature of 70°F when the surrounding outside temperature was maintained at 10ºF, 20ºF, 30ºF and 40ºF.
Among their findings, Kansas State University concluded that:
• Power*e™ Glass windows substantially reduce or eliminate the need for other heating systems.
• Power*e™ Glass heated buildings use up to 40% less energy than buildings heated by natural gas and other conventional heating systems and produce more consistent and comfortable room conditions.
• Power*e™ Glass’ insulating and heating benefits combine to be essentially 100% efficient.
• Power*e™ Glass heated buildings will be more thermally comfortable than buildings heated with other conventional heating systems.
• Power*e™ Glass stops virtually all conventional building heat loss through the heated windows.
• Approximately 85% of the power to the Power*e™ Glass heats the interior space - regardless of the outside temperature.
• Power*e™ Glass delivers approximately 136 BTU/sq. ft. of glass to the interior side of a window when operated at a glass surface temperature of 115ºF, and the delta T (temperature differential between the interior and exterior) is 60ºF.
• In comparison testing, natural gas forced air systems were at best 75% efficient and were not able to match the consistent comfort produced by Power*e™ Glass windows. In reaching this conclusion, consideration was given to average efficiencies of installed systems, duct losses, infiltration losses, new furnace standards and the impact of costs on upgrading systems to more efficient furnaces. Studies have found that upgrading to 90% or 95% efficient furnaces is not cost effective in many climates and that it is more cost effective to upgrade to 80% efficient furnaces.
