Critical Need: 

Numerous U.S. buildings have single-pane windows that do not insulate the building or its occupants as well as double-pane units or other advanced windows. Single-pane windows are also inferior in condensation resistance and occupant comfort. However, complete replacement of single-pane windows with efficient, modern windows is not always feasible due to cost, changes in appearance, and other concerns. Retrofitting, rather than replacing single-pane windows, can reduce heat loss and save roughly the amount of electricity needed to power 32 million U.S. homes each year. One avenue is to replace just the pane itself with an improved windowpane. To be economical, these new types of manufactured windowpanes must be able to be installed into the existing window sash that holds the windowpane in place. To be adopted, they must improve window energy efficiency and other important qualities without substantially affecting the window's appearance.

Project Innovation + Advantages: 

Triton Systems will develop and demonstrate a high efficiency windowpane system that will encourage retrofitting of single-pane windows. Triton's Multifunctional Glazing System (MGS) will potentially provide a better balance of performance with cost and weight versus double-pane insulated glass units. The system combines a nanoparticle-polymer composite film with an insulating layer of a porous material filled with air, to provide thermal insulation. The team will enhance the pane's durability by incorporating a nanocomposite edge seal. The thickness of the MGS will be less than ¼ inch, ensuring its compatibility with most single-pane window sashes as a direct glazing replacement.

Potential Impact: 

If successful, Triton's innovations will enable energy-efficient retrofits for the substantial remaining stock of single-pane windows in the United States. Retrofitting single-pane windows could produce significant environmental and economic benefits. By consuming less electricity, natural gas, and/or heating oil to warm a building, these technologies could help avoid greenhouse gas emissions associated with these energy sources. Moreover, these technologies could help reduce building energy consumption and save money for homeowners and businesses. Consumers adopting these retrofits could also benefit from improved window performance, including greater comfort and reduced condensation in cold weather and improved.
