Window Volume Purchase Program Working to Lower Cost, Improve Availability

R-5 windows can reduce average heat loss by 30-40% over common ENERGY STAR-qualified products (with an R-3 value), and low-e storm windows have the potential for twice the energy savings of those without a low-e coating, according to Department of Energy (DOE) estimates. The problem? Because of low demand these windows are only available today at a considerable price premium through special order.
A new national volume purchase program is working to change that by spurring availability and lowering the cost of these high efficiency window products for residential and commercial installations. Manufacturers and other stakeholders will gather in Washington, DC, on May 27th to kick off the “Highly-Insulating (R-5) Windows and Low-e Storm Windows Volume Purchase Program,” an effort led by DOE.
The two-pronged strategy behind the volume purchase includes a production engineering request for proposals for manufacturers willing to develop high volume factories for qualifying products. Secondly, the agency will spread the word to building owners, contractors and other stakeholders and help aggregate buyers in order to reduce risk for manufacturers making investments in their facilities.
Information about participating manufacturers and how to purchase qualifying products will be available on a DOE website after the May meeting. For more information in the meantime, visit
