Energy Star Windows

  • Energy Star Windows

ENERGY STAR is a joint program of the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy helping us all save money and protect the environment through energy efficient products and practices. Results are already adding up. Americans, with the help of the ENERGY STAR program, saved enough energy in 2007 alone to avoid greenhouse gas emissions equivalent to those from 27 million cars - all while saving $16 billion on their utility bills.

For The Home

Energy efficient choices can save families about a third on their energy bill and similar savings on greenhouse gas emissions, without sacrificing features, style, or comfort. ENERGY STAR helps you make the energy efficient choice.

When looking for new household products, look for the ENERGY STAR seal. They meet strict energy efficiency guidelines set by the EPA and US Department of Energy. When looking to make larger improvements to your home, the EPA offers tools and resources to help you plan and undertake projects to reduce your energy bills and improve the comfort of your home. Since the energy efficient performance of windows, doors, and skylights varies by climate, product recommendations are given four U.S. climate zones. For comparisons among ENERGY STAR products and selecting the best product available read Buying Energy Efficient Windows or go to www.nfrc.org.

 

 

Changes In The Energy Star Qualifications

The Department of Energy (DOE) issued its revised criteria for the Energy Star windows, doors, and skylights program.

The FULL REPORT is available, please follow the link. 

Specifics

DOE tightened the U-factor criteria to the 0.22 level in the Northern zone, to 0.25 in North-Central, to 0.28 in South-Central, and to 0.32 in Southern. Previously choosing not to set an SHGC maximum in Northern zone, DOE updated the criteria in all but North-Central, which remains at 0.40. 

The new Energy Star criteria goes into effect October 23, 2023.
