If you wish to participate, you will need an energy audit done both before and after the installation of new windows. There are several energy rebate programs available that will partially offset the cost of buying energy-efficient windows. And windows that qualify for the new “ ENERGY STAR Most Efficient” designation are up to 40% more efficient than a standard window. If you’re in the market for windows, choosing Energy Star certified models can save you an average of 8% on your energy bills compared to a standard window. The lower the U– factor, the greater a window’s resistance to heat flow and the better its insulating properties. There are several measures of energy efficiency – the most useful being the U-factor, which measures the rate of heat loss in a window assembly.

When shopping for windows it’s helpful to understand all the types of windows that are available, as well as the hardware components of all windows, as shown in this illustration.

To further conserve energy, install white-backed window shades, drapes, or blinds on south- and west-facing windows to reflect summer sunlight back outside the house. (Low-E or low-emissivity coatings are virtually invisible layers of microscopic metallic oxide on the glass surface that minimize heat transfer through windows.) In summer, low-E coatings on glass windows reduce solar heat gain without darkening the glass. In winter, energy-efficient windows reduce heat loss, air leakage, and create warmer window surfaces that improve comfort and minimize condensation.

Simply put, older windows can cause heat loss in winter and heat absorption in summer that increases the cost of air conditioning. It may feel like Old Man Winter is finally loosening his grip – but installing energy-efficient windows will save you money year-round.
