Energy Savings Advice
ENERGY SAVINGS WHAT TO DO?
Look for the Energy Star:
The Department of Energy (DOE) and the Environmental Protection Agency (EPA) have developed an ENERGY STAR (www.energystar.gov) designation for products meeting certain energy performance criteria. Since performance of windows and skylights vary by climate, product recommendations are given for the four ENERGY STAR climate zones.
Look for Efficient Window Properties on the NFRC Label:
The National Fenestration Rating Council NFRC (www.nfrc.org) has developed a window rating system based on whole window product performance. The NFRC label provides the only reliable way to determine the energy efficient properties and to compare products. The NFRC label appears on all fenestration products which are part of the ENERGY STAR program.
Compare Annual Energy Costs for a Typical House:
Computer simulations for a typical 2000 square-foot house are used to compare the annual energy performance of different window types.
