The Partnership for Advanced Window Solutions (PAWS) is a collaborative that promotes cost-effective, high performance window solutions for the nation’s new and existing building stock.
Launching with multi-year support from the U.S. Department of Energy and in-kind support from partners, the PAWS Collaborative will employ a variety of proven strategies to transform window markets.
Although they constitute only 10% of the surface area of a typical home, traditional windows are poor energy performers. Windows usually account for 30-40% of the heat loss in winter and often add to cooling peaks and discomfort in summer.
As the U.S. prioritizes net zero energy buildings, addresses carbon emissions and confronts the challenges of decarbonizing the grid, there is a pressing need to dramatically increase the availability and use of highly efficient window products. Switching from today’s code compliant, double pane low-e window in a new home to new R5 solutions can save between 7 and 16 percent of a home’s energy use, depending on climate. In an older home, retrofitting its single glazed windows with R5 windows can provide much larger energy savings.
Through collaborative research and programs, PAWS will:
