University of California, San Diego (UC San Diego)

The University of California, San Diego (UCSD) will develop a polymer-based thermal insulating film that can be applied onto windowpanes to reduce heat loss and condensation. The team's approach uses polymer-based coatings with specifically designed structures. Heat management is gained by the thermal conductivity of polymer and the internal thermal barriers. The coating is inherently low-emissivity, and also resists condensation and abrasion. The technology is initially designed for single-pane windows, but can be expanded in the future for use in double-pane windows, doors, and roofs, as well as potential applications in the automobile, aerospace, and military industries.

If successful, UC San Diego’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 economic and environmental benefits. The team estimates that wide implementation of its coating could reduce single-pane window heat loss by nearly 60% per year, which would conserve 1.2 quads of energy and save consumers $12 billion in energy costs. Consumers adopting these retrofits could also benefit from improved window performance, including greater comfort and condensation resistance in cold weather.
