Making Smart Windows Even Smarter
Researchers have created a thin coating of nanocrystals embedded in glass that can dynamically modify sunlight as it passes through a window.
Significance and Impact
Unlike existing technologies, the coating provides selective control over visible light and heat-producing near-infrared (NIR) light, so windows can maximize both energy savings and occupant comfort in a wide range of climates.
- Builds on previous advances that uses the electrochromic effect, where a small jolt of electricity switches the material between NIR-transmitting and NIR-blocking states
- New material provides independent control over both visible and NIR light
- Recently recognized with a 2013 R&D 100 Award and in the early stages of commercialization
