What are Energy-Efficient Windows?
When it comes to Energy-Efficient Windows, climate plays a big role. The experts at ENERGY STAR have divided the country into four different zones, based on variables like climate, temperature fluctuations, humidity, and rainfall. That way, you can be sure you’re buying exterior home products like windows and doors rated for your specific climate zone. Whether you live in a warm climate or a cold one, you can rest assured that your ENERGY STAR-rated products will help save you money on your energy bill. Energy Star recognizes windows with high quality as ‘Energy-Efficient Windows’, indicating that they provide exceptional energy efficiency.
Energy Star Rating for Energy-Efficient Windows
The ENERGY STAR label is a federally regulated symbol that displays a product’s efficiency in using energy. The label is most commonly seen on appliances and electronics, but can also be applied to homes and buildings. For homes, ENERGY STAR evaluates window performance through various ratings, all of which are based on the U-Factor. The U-Factor, or the rate of heat transfer, is just one of the ways in which ENERGY STAR rates windows. Other methods include the solar heat gain coefficient (SHGC), air leakage, visible transmittance, and condensation resistance. If your home’s windows face the sun, installing replacement windows with a lower U-Value is even more important. Replacing old, inefficient windows with ENERGY STAR certified ones can help you save money on your energy bills and make your home more comfortable throughout the year.
