ENERGY STAR climate zones

A voluntary program established by the EPA in 1992, ENERGY STAR helps businesses and individuals save money and protect the climate by identifying and promoting energy-efficient products and buildings. Products with the ENERGY STAR designation must meet third-party certification based on testing in EPA-recognized labs. Additionally, ENERGY STAR-qualified products are subject to “off-the-shelf” testing at any point throughout the year.
