The research team of Dr. Han Chi-Hwan of the Korea Energy Research Institute (KIER) has developed a new smart window technology. It is able to automatically adjust the amount of light entering the room by changing the color of the window depending on the intensity of the sun's rays.
At the same time, the technology does not require electricity due to the presence of a light-absorbing layer. The researchers explain that this could reduce home energy prices by 30-50%. And since there is no need for a separate power supply, it helps keep costs down as well.
The smart window blocks sunlight well over a large area, so it can be used for large buildings with high cooling costs. Glass blocks both the visible light spectrum and infrared rays.
The research team has also succeeded in creating shielding technology - essentially developing a film that can be glued to pre-existing window panes. If the production of such films is successful, they can be used not only on buildings, but also in cars, ships and airplanes.
