2.- Check the Ratings
All new windows must meet local building code requirements, but not all offer the benefits of efficiency, such as lower utility bills and increased comfort. Take these three steps toward efficiency:
- NFRC Ratings: NFRC’s easy-to-understand efficiency ratings are displayed on labels affixed to windows and help you make comparisons before buying. They should remain in place until after installation and, once removed become part of the documentation you’ll need to qualify for any rebates or incentives you may be eligible to receive from utilities and from state and local governments.
- ENERGY STAR®: Windows certified by the U.S. Environmental Protection Agency’s ENERGY STAR program save homeowners an average of 12% on monthly utility bills. Windows are not eligible for ENERGY STAR certification unless first rated by NFRC.
- MOST EFFICIENT: ENERGY STAR’s Most Efficient program recognizes products that use cutting-edge technologies to deliver the greatest efficiency.
