On hot days, the material helps cool the building by dissipating up to 92% of the heat it contains. But on colder days, the material only emits 7% infrared radiation, helping to keep you warm.
“Such a smart material allows us to maintain the temperature in the building without huge energy costs,” said the authors of the development. The scientists calculated that in an average commercial building, the electricity used to trigger electrochromic changes in a material would be less than 0.2% of the total electricity consumption. So, development will save.
