Energy Star is an international standard for energy efficient consumer products originated in the United States of America.
Window have an amazing effect on the cooling and heating needs and costs of a Canadian home, as well as the comfort level experienced by its occupants. Windows are easily the weakest link in a home for heat gain in the summertime and heat loss in the wintertime.
An energy efficient window is one that helps to keep a constant temperature in a room, thus conserving on the energy wanted to heat or chill the room. For a start, the energy efficiency of any window can be improved by insuring that it is well looked after and has not got openings in the frame that will cause drafts.
New homes that meet strict guidelines for energy efficiency can qualify for Energy Star certification. An Energy Star qualified home uses at least 15% less energy than standard homes built to the 2004 International Residential Code (IRC). They usually include properly installed insulation, high performance windows, tight construction and ducts, energy efficient cooling and heating systems, and Energy Star qualified appliances, lighting, and water heaters.
There are plenty of ways manufacturers can meet the standard of being “energy efficient”. A lot of it is pretty technical for average people. From the homeowner’s point of view, when you are purchasing energy efficient, you are looking to purchase windows that represent a measurable improvement in keeping cold out on cold days and heat out on hot day.
