As sunlight passes through a building's windows it can cause indoor temperatures to rise, to the point that the structure's power-hungry air conditioning system has to be used. A new switchable window ...

Physicists at the University of Colorado Boulder have designed a new material for insulating windows that could improve the energy efficiency of buildings worldwide—and it works a bit like a high-tech ...

Assisted by quantum physics and machine learning, researchers have developed a transparent window coating that lets in visible light but blocks heat-producing UV and infrared. The coating not only ...

Windows welcome light into interior spaces, but they also bring in unwanted heat. A new window coating blocks heat-generating ultraviolet and infrared light and lets through visible light, regardless ...

Q: I am considering installing glass block windows on some first floor ones for security. Is the solid glass energy efficient and can I have some summertime ventilation with them? A: From a security ...
