Energy Star 7.0 Criteria Updates
Kasson & Keller Inc. has updated our window systems to reflect the new ENERGY STAR 7.0 criteria.
Why is ENERGY STAR UPDATING criteria to 7.0?
The new 7.0 performance specifications have been in development for the past four years, tested by Lawrence Berkeley National Laboratories, the EPA, and the Department of Energy. They will officially go into effect on October 23, 2023.
In part, updating the requirements is a reaction to market saturation of ENERGY STAR products and is intended to help drive innovation and change. Additionally, the estimated energy cost savings, if 7.0 is adopted nationwide on all residential windows and doors sold, exceeds $156 billion annually, with over 53 billion pounds of yearly greenhouse gas emissions reduced.
What are the high-level differences between 6.0 and 7.0?
- Continued changes toward more energy efficient window and door products
- Lower U-Factors with SHGC changes, designed to improve efficiency.
- There are some changes to ENERGY STAR Qualification zone map (see below)

What should contractors tell homeowners?
Windows that meet 7.0 criteria are a long-term investment which will make homes more comfortable in every season and reduce the cost of regular energy bills.
Homeowners who choose 7.0 rated windows and doors can save thousands in energy costs over the lifetime of these products, while helping to reduce emissions.
