Republic Windows & Doors of Chicago has announced that it has qualified as an ENERGY STAR Canada participant. According to the company's announcement, the qualification means all of Republic's windows with a minimum of low-E HP glass meet ENRGY STAR requirements in one or more of the four climate zones in Canada.

Steve Hopwood of Natural Resources Canada said the qualification process is twofold.

"First the manufacturer must agree to adhere to the labeling rules and parameters for use of the ENERGY STAR symbol," Hopwood said. "That's the easier part. Second, the manufacturer must fill out a detailed spreadsheet for each product that specifies thermal performance ratings and zone qualifications. We verify the ratings with the NFRC for U.S. companies or with other accredited organizations (such as CSA for Canada). Once all criteria are meet the manufacturer becomes a certified ENERGY STAR Canada participant."
