See-through window coating that blocks heat could reduce air conditioning costs

The end product was a mere 1.2 microns thick — around 58 times thinner than the average human hair. According to the team, their transparent radiative cooler is capable of outperforming all other heat-reducing glass coatings already on the market.

In fact, they said, “This cooler may lead to an annual energy saving of up to 86.3 megajoules per metre squared in hot climates compared with normal glass windows.”

Alongside use in buildings, the transparent radiative cooler could also find application on the windows of cars and other such vehicles, helping to keep their interiors cooling even when parked or moving in the glare of the Sun.

The coating technology, therefore, may help address some of the challenges humanity is likely to face as climate change leads to warmer temperatures across the globe.
