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. Window performance can be improved either by transparent, adhesive products that can be applied directly onto existing windows or by manufactured windowpanes that can be installed without replacing the window sash that holds the windowpane in place. Innovative technologies to enable inexpensive, high-performing products from these two categories are needed to accelerate effective retrofit options.

Project Innovation + Advantages: 

Eclipse Energy Systems, Inc. will further develop its proprietary transparent electrical conductor material (EclipseTEC) for use in low-emissivity (low-e) window films. Transparent, low-emissivity coatings improve building energy efficiency by reducing heat loss through the windows. Over the course of the project, the team will transfer their present technology for depositing EclipseTEC films to scalable manufacturing processes while preserving the desirable optical and low-e properties. Eclipse will partner with one or more companies offering thermal insulation solutions and incorporate EclipseTEC into their panes and/or applied products. The unique combined system will offer significant energy savings over traditional single-pane windows.

Potential Impact: 

If successful, Eclipse Energy Systems' 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.
