ENERGY STAR®

What is ENERGY STAR®?

The ENERGY STAR® program is run by the Environmental Protection Agency, in conjunction with the Department of Energy, within the United States and by Natural Resources Canada. The purpose of The ENERGY STAR® program is to encourage window and other manufacturers to voluntarily develop energy-efficient products. Windows that meet certain energy saving requirements are given the blue ENERGY STAR® label, meaning a product has gone through stringent quality and performance tests and met energy-saving criteria.
