"Smart Windows"
Scientists have created glass for windows that save up to 50% on lighting and heating costs. “Smart windows” globally “cut off” both light and heat, and also offer fine-tuning modes. For example, on a dazzling winter day, you want the room to be dark, but you also want warmth, and thanks to the fine tuning of the light spectrum, this can be arranged. Glasses will "cut off" the visible spectrum, darkening the room and letting infrared rays through, so that the room heats up. The technology also works in the opposite direction: in spring and summer, glass will let in more visible light, but “cut off” infrared heat rays As a result, the result of Canadian research can serve not only for comfort, but also to save electricity for heating / cooling rooms up to 50% .
