DOE Roadmap Presentation Features “Windows for Today and Tomorrow”June 7, 2011
On June 7, Marc LaFrance of the United States Department of Energy’s (DOE) Office of Energy Efficiency and Renewal Energy (EERE) delivered a presentation on the Building Technologies Program (BTP). The EERE’s mission is to develop cost competitive technology, facilitate commercialization and deployment to the marketplace.
Focusing on energy efficiency and carbon use, LaFrance pointed out that compared to industry and transportation statistics, buildings consume 38 percent of carbon emissions. Combined, the residential and commercial market account for 39 percent of U.S. primary energy consumption, indicating that total U.S. energy consumption is on the rise. As BTP’s funding has necessitated a dramatic increase over the past five years, there is an apparent demand in the marketplace for window development.
Looking ahead to the next generation of windows is a need to be highly insulating, with a goal U value of 0.10 (SI U value 0.56), and vacuum glazing which has the potential for high light transmission. An example of a dynamic window with no blinds was shown from Ball State University in Muncie, IN, which can be cost neutral within five years.
Complementary to an added layer of protection in windows is dynamic solar control. Providing passive heating and dramatic peak cooling reduction with SHGC 0.53-0.09, allows windows to be more marketable with the hope that prices will drop with greater investment. A number of other innovative projects are underway and will be competing in the market beginning in 2012, with the belief that advanced windows can become energy producers.
Additionally, the presentation discussed Phase I of the Windows Volume Purchase program which currently includes 40 certified suppliers. Phase II of the program is slated for 2012 and will include commercial products and will involve some revisions to the bid process. More details are available at http://www.windowsvolumepurchase.org/
LaFrance also addressed the key policies moving forward with ENERGY STAR, as managed by the EPA, including analyzing triple and double glazing and pursuing films and low-e storm products. He went on to discuss tax credits, international activities and the new Envelope and Windows Blog available at http://www.eereblogs.energy.gov/buildingenvelope/.
