DOE Launches Website for High-Efficiency Windows
High performance R-5* windows and low-e storm windows are available for purchase through this website from a number of vendors who have qualified to participate in the volume purchase program.
The U.S. Department of Energy today announced the launch of the Highly-Insulating R-5 Windows and Low-e Storm Windows Volume Purchase Program, part of a multi-year integrated strategy to transform the market for high efficiency windows. The initiative will facilitate the broader deployment of these windows by pairing manufacturers with buyers looking to purchase large volumes of windows and by setting performance expectations for two new types of energy efficient windows. This will provide support for window manufacturers to help overcome the initial costs associated with producing windows at an even higher efficiency level while connecting volume buyers with pre-cleared suppliers.
"The Department of Energy has played a key role in rapidly advancing window technology in the past few years. This program will help move these technologies into the marketplace, providing significant energy savings to homes and businesses across the country," said Roland Risser, DOE's Building Technologies Program Manager. "This initiative will help drive demand and increase the number of offerings available to builders and project developers."
The program includes both Highly-Insulating R-5 (U value 0.2) Windows and Low-e Storm Windows. When replacing windows or building a new building, R-5 Windows can reduce heat loss through the window by 30 to 40% compared to a typical R-3 window available today. In situations where full replacement is not an option, Low-e Storm Windows, which fit over existing windows, can be used to reduce heat loads by up to 20%. The savings for both R-5 windows and Low-e Storm Windows are a significant improvement over products available today—and many meet DOE's price premium target of less than $4 per square foot. With higher energy performance and lower purchase prices, windows can become an even more cost effective measure for building retrofits.
Volume purchasers of windows, including government agencies, builders, energy retrofitters, renovators, and weatherization providers, will gain online access to window sellers whose products are certified to meet the High-Insulation R-5 and Low-e Storm Windows specification. Buyers can review size and price ranges and then connect directly to the vendors' Web sites to purchase. The program includes more than 30 suppliers.

The Volume Purchase Program received significant interest from manufacturers, the building industry, and other key industry stakeholders. More than 50 eligible proposals were submitted from suppliers; over 30 suppliers meeting all program requirements are currently listed on the Web site ready to sell windows products. Today's launch event co-hosted by the National Association of Home Builders (NAHB) will include participation from a broad spectrum of building industry stakeholders, including NAHB, American Architectural Manufacturers Association, the Alliance to Save Energy, Community and Economic Development Association of Cook County, Illinois (CEDA), and Habitat for Humanity.
Windows that are part of the program must have National Fenestration Rating Council (NFRC) thermal performance certification and minimum structural certification in accordance with the North American Fenestration Standard (NAFS). Additionally, all storm windows must have their glass type registered in the International Glazing Database created by Lawrence Berkeley National Laboratory (LBNL).
