 What is the Efficient Windows Collaborative (EWC)?
The EWC website is an unbiased source of information for consumers. We help consumers understand how windows impact the energy performance of the home, how windows work, what types of technologies to look for, and we show consumers how much money they can save by improving the performance of their windows in different parts of the country.
Why should consumers worry about windows?
Energy efficient windows can save consumers up to 30% on their heating and cooling bills. Windows impact the need for heating a home in winter and cooling a home in summer.
So, which window should a consumer purchase?
Selecting an energy efficient window product can be more complicated than selecting other products such as appliances. An Energy Star refrigerator will use the same amount of energy regardless of the home design or location of the home. But windows will perform differently based on the climate, the home design and other features. This is because windows interact with the environment.
What is the most important technology consumers should look for?
Low-E coatings are the newest technology to improve the energy performance of windows. But consumers must be aware of the different types of low-E products that are available. High-solar gain low-E products are best for heating-dominated climates. Low-solar-gain low-E products are best for cooling dominated climates.
How can consumers identify the most efficient products?
Efficient technologies are transparent in windows which is why it is important for consumers to look for labels on windows. We educate consumers about two important labels. Energy Star labels on windows indicate products that will significantly improve the energy performance of a home in a given climate. National Fenestration Rating Council (NFRC) labels provide measurements of window energy performance.
Are there any programs to help consumers purchase efficient windows?
Congress is currently considering legislation that will provide tax credits for consumers who apply efficient technologies to their homes. Additionally, many utility companies sponsor programs that provide either rebates or low-interest loans for energy efficiency upgrades to both new and existing homes. Consumers should contact their local utilities for more information. Finally, there are energy efficient mortgages available to consumers making efficient improvements to their homes.
What is your best advice for consumers?
Consumers should spend time on our website, www.efficientwindows.org in order to identify the product that will be best for their homes. This will arm consumers with important information as they shop for windows. With efficient windows they can save money and they will be helping to protect the environment.
