When added together, every homeowner's individual savings will have a significant impact on the national energy problem.
According to U.S. Government estimates, the average household spends over 40% of its annual energy budget on heating and cooling. Energy Star qualified windows can reduce energy costs by 15% or more.
Cardinal invests heavily in research and development for new glazing technologies that reduce household power consumption. Our annual production of energy efficient glass coatings and insulating glass products conserves energy equivalent to the production of 14 offshore drilling platforms.
Estimates from the Alliance to Save Energy indicate that nationally, the air-conditioning savings from windows using low solar gain glass like Cardinal's LoĒ² coatings would eliminate the need to build two power plants per year, and over 20 years would save over $750 million in electricity costs and eliminate 1.5 million tons of carbon emissions.
Studies at Lawrence Berkeley National Laboratory suggest that if all windows purchased over the next fifteen years incorporated low-E coatings, gas fills, and a few other readily available efficiency improvements, our collective annual energy bill could be reduced by 25 percent or over $2.5 billion per year by 2010 (Geller, Thorne 1999).
