3 DOE Goals for Windows Programs Highly Insulating Windows Goal is U-factor 0.10 Possible vacuum glazing Dynamic glazing Market-Based Approach Avoid use of codes and standards Many new projects underway in Technology procurement Prototype Concept Window Highly Insulating and Dynamic SHGC Program Name or Ancillary Text eere.energy.gov

4 ENERGY STAR: DOE Criteria Now Led by EPA ENERGY STAR for Windows Effective January 2010 EPA: Doug Anderson Program Name or Ancillary Text eere.energy.gov

5 Current Residential Windows Market Home Depot Three largest window categories Over 85% Energy Star Compliant R3 is now the BASELINE 5 Program Name or Ancillary Text 5 eere.energy.gov

6 Highly-Insulating R-5 Windows Typical ENERGY STAR windows have an R-value of ~ 3 and typically require two R-5 panes Highly-Insulating of glass with an Argon Windows gas filling and an efficient frame. Whole-window R-value of 5 (U-factor ~ 0.2) is currently the top tier of energyefficient windows for cold and mixed climates. Typically require three panes of glass with a Krypton gas filling, and a highly efficient frame and spacers. Increasing the R-value from 3 to 5 reduces average heat loss through the window by over 30% and improves occupant comfort. 6 Program Name or Ancillary Text eere.energy.gov

7 Low-E Storm Windows Storm windows can reduce heat loss through the windows by 25% to 50% compared to single pane windows with a U-value of 1.1. Low-E storm windows save even more energy. HUD s PATH program (with DOE and industry partners) sponsored a field evaluation concluded that low-e storm windows reduced heating load by 20% and achieved less than a 5 year simple payback. Chicago weatherization agency identified 6 older homes with single pane windows (U-value of 1.1) for evaluation. Retrofitting of low-e storm windows can be a very cost effective solution in select residential and commercial buildings even in moderate/mixed climate zones. 7 Program Name or Ancillary Text eere.energy.gov
