Window Replacement and the Energy Star Program

The Department of Energy wants consumers to know that, beginning January 2010, ENERGY STAR windows will be required to meet new, tougher requirements to help Americans use up to 24 percent less energy in their homes. High-efficiency replacement windows with ENERGY STAR labels and blue Federal Tax stickers may be eligible for a $1,500 tax credit.

Currently, window replacement products with U-factor and Solar Heat Gain Coefficient (SHGC) ratings of 0.30 or less qualify. Homeowners need to obtain the manufacturer's certification statement from the retailer or manufacturer to apply for the tax credit.

Window Replacement Can Save Energy and Money

ENERGY STAR reports that homeowners can save $126-$465 a year in energy costs when installing qualified replacement windows in place of single-paned sets. And replacing older double-paned windows can still bring a $27-$111 savings in utility costs. Savings are higher in cooler parts of the United States.

Replacement windows with qualified ratings are made to specifications depending upon climate and region. Installers may recommend specific windows for each side of your home. U-factor and SHGC ratings are determined by the National Fenestration Rating Council (NFRC). The ENERGY STAR program was created by the US Environmental Protection Agency in 1992 to create a list of products and manufacturers with products that met NFRC ratings.

The ENERGY STAR list includes window replacement products, appliances, heating and cooling equipment, lighting bulbs and fixtures, home insulation products, and water heaters. To get the most out of your replacement windows, ENERGY STAR recommends hiring trained professions who will follow the manufacturer's instructions. Failure to meet installation specifications may void the warranty.
