A domestic property loses as much as 20 percent of its heat through windows. For big glassy commercial buildings, that figure is a lot higher, resulting in big heating bills and inevitable disputes ...

Windows are great for letting in light, but in summer months that comes with an unwanted side order of heat, causing many people to run the air conditioning non-stop. Now, researchers have developed ...

Semitransparent solar cells with natural looking color and strong heat blocking offer a realistic way for windows to generate ...

With the addition of some cheap nanoantennas, your average window can now be turned into an efficient solar heater. Just as Elon Musk’s Tesla wants to turn our otherwise dormant roofs into powerful ...

A California energy startup has designed windows with built-in solar panels, which they hope will hasten the widespread transition to carbon-free electricity sources the state is encouraging with new ...

Generating energy from sunlight is essential for reducing CO2 emissions. However, it takes a lot of space to install all the solar panels needed for our energy supply on land. What if you could use ...

Q: I bought a house with bedrooms that face the south side of the house. During the summer, the heat in those rooms is brutal. They already have ceiling fans, but I am wondering if putting up some ...

These windows—dubbed "thermochromic" for their ability to change colors in response to heat—can convert sunlight into electricity using minerals called perovskites and single-walled carbon nanotubes.

In the IN 2 NEXT project, PV-coated windows from NEXT Energy Technologies were tested against traditional commercial windows, tracking performance based on their respective solar heat gain coefficient ...
