Technology Description:

The University of California, Los Angeles (UCLA) will harness advances in nanotechnology to produce thermally insulating transparent barrier (THINNER) coatings to reduce heat losses through single panes of glass. The porous coatings consist of multiple layers of silica/titania films that can simultaneously control the transmission of heat, light and thermal radiation. The internal structure of the coatings is determined by a polymer lattice that is later removed. This leaves a robust porous oxide layer that is transparent and thermally insulating. In addition to reducing heat loss, the coatings will reduce water condensation on the inner window surface and block harmful ultraviolet light. The project will also develop a scalable, high-temperature spray-on process to inexpensively deposit the coating onto glass at the factory.

Potential Impact:

If successful, UCLA’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. 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 condensation resistance in cold weather and better soundproofing. Finally, by consuming less electricity, natural gas, and/or heating oil to warm a building, these technologies reduce the greenhouse gas emissions associated with using these energy sources.
