Energy Rating of Windows
EQ Windows is the Swedish Window Energy Rating Organisation responsible for Window Energy Ratings in Sweden. The Swedish Energy Agency initiated the Window Energy Rating in year 2006. Since June 2009 the Window Energy Rating and Labeling is monitored by EQ Windows, a non-profit organization.
By choosing energy rated windows, you are guaranteed a verified window U-value. The windows are tested and/or the U-value is simulated by an idenpendent certified testing institute. EQ Windows checks and validates the results and provides the manufacturers with energy labels and "locked" product sheet for each energy rated window type. Finally the products are listed on this home page from which the product sheet can be downloaded.
The organization EQ Windows logotype
The ratings scheme for Energy EfficientWindows is a voluntary scheme that uses labels similar to those seen on household appliances. The label tells you how energy efficient the windows are. The rating scale is A - G where A is for windows with U-value 0,9 W/m2K or below and G for 1,5 W/m2K.
The Swedish label
The chairman of the organization and project leader is Diana Avasoo, a window and glass expert at WSP Environmental in Sweden.
Windows, taps and home insulation will in future have to carry energy performance labels in the European Union after EU negotiators reached a deal on 17th November 2009. Within about a year, the EU's energy-labelling scheme will be extended to cover goods beyond the existing narrow range of domestic electrical appliances, such as fridges, dishwashers, washing machines and light bulbs. The scheme will now be extended to all "energy-related products," including taps, shower-heads, televisions, windows and building materials.
