Scalable thermochromic smart windows with passive radiative cooling regulation

A passive turnoff Passive radiative cooling technology uses the infrared atmospheric window to allow outer space to be a cold sink for heat. Because the transition is simply temperature dependent, this effect also happens passively.

• 1 However, this effect is one that is only helpful for energy savings in the warmer months.
• 2 used the metal-insulator transition in tungsten-doped vanadium dioxide to create window glass and a rooftop coating that circumvents this problem by turning off the radiative cooling at lower temperatures.
• 3 Because the transition is simply temperature dependent, this effect also happens passively.

This work deepens our understanding of the fundamental laws governing the universe, from subatomic particles to cosmic structures.
