Notre Dame Researchers Develop Heat-Blocking Window Coating

The innovative coating could slash air conditioning costs by over a third, offering a new solution for energy efficiency in buildings and vehicles.

Scientists at the University of Notre Dame have developed a new window coating that blocks infrared and ultraviolet light while allowing visible light to pass through, potentially reducing air conditioning costs by more than one-third.
The coating works by stacking ultra-thin layers of silica, alumina, and titanium oxide on a glass base, with an additional layer of silicon polymer to enhance heat reflection.
The new technology is effective regardless of the sun's angle, addressing the challenge of sunlight entering windows at oblique angles during the hottest parts of the day.
Quantum computing was utilized to optimize the layer configuration, ensuring maximum light transmission and minimal heat passage.
The innovation could be applied to homes, offices, and car windows, offering a cost-effective way to reduce energy usage and improve indoor comfort.
