We simply want to make it easier for our nation’s builders to do their job in the most effective ways. 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. And we’re on a mission to change that.
The PAWS collaborative includes government agencies and research organizations, regional energy efficiency groups, utilities, builders, and window-solutions manufacturers.
Better Windows, Smarter Budgets: High Efficiency, Not High Expense Washington, D.C. | August 18, 2025 – Following the success of its most-attended session at the 2024 Energy and Environmental Building Alliance (EEBA) Summit, the Partnership for Advanced Window Solutions (PAWS) is returning to the stage in 2025 in St Paul, MN, with a powerful update […]
“Windows are the poorest thermal components in the building envelope in residential and commercial buildings, impacting human health and comfort, and costing building owners more than $50 billion per year in energy costs.” — Marc LaFrance, U.S. Department of Energy
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 windows in a new home to new R5 solutions can potentially save 7-16% of a home’s energy use, depending on the climate. In an older home, retrofitting its single-glazed windows with R5 windows can provide much larger energy savings in the long run.
