How will I know if a window, door or skylight is ENERGY STAR qualified?
• It’s easy – just look for the familiar ENERGY STAR mark on the product or in the manufacturer’s literature. If the map on the ENERGY STAR label indicates that the product is qualified in the Canadian climate zone where you live, you’ve found a winner! To maximize your long-term energy and cost savings, consider purchasing a product that is ENERGY STAR qualified for a colder climate zone than where you live. This strategy is especially recommended if you live in a location that is significantly higher in elevation than the surrounding area, such as in southern and central British Columbia.
