What is ENERGY STAR 7.0?
The ENERGY STAR Version 7.0 is a set of specification requirements for certification that provides a significant jump in efficiency and savings. According to EPA research, if all residential windows and doors sold in the United States were certified to ENERGY STAR Version 7.0, the energy cost savings would grow to more than $156 billion each year and more than 53 billion pounds of greenhouse gas emissions would be avoided annually.
