Thermochromic glazing can control sunlight passing through windows based on temperature, helping save energy in buildings. A study on TiO2@W-VO2 thermochromic glazing shows it can change how much sunlight comes in, affecting indoor lighting and energy use. The glazing can adjust near-infrared light, impacting visual comfort, light color, and artificial lighting needs in an office room. By combining material development and analysis, the glazing's properties can be optimized for balancing solar control, light transmission, and color appearance.
