What is Energy Star version 7?
Recently, the U.S. Environmental Protection Agency’s (EPA) ENERGY STAR® program released its final version 7 specification for Residential Windows, Doors, and Skylights that establish higher energy-efficiency benchmarks for products to earn EPA’s coveted ENERGY STAR certification. This new specification outlines more demanding certification criteria of various fenestration products.
The energy performance of windows is essential to overall building efficiency and its environmental impact. More efficient windows will reduce your home’s carbon emissions on day one, independent of what source of energy is used to heat and cool your building. Although windows only account for about 10% of an average home’s surface area, approximately 35% to 45% of the heat homes lose in winter months pass through windows. More insulative windows, like the industry-leading models that the new ENERGY STAR criteria will certify, can bring those losses down considerably, which saves energy and money.
