Thermochromic windows are special types of glass that change their tint based on temperature. When the temperature rises, these windows darken to reduce heat and glare from sunlight, helping to keep indoor spaces cooler. This feature can enhance energy efficiency by minimizing the need for air conditioning. These windows work by using materials that react to heat, often incorporating thermochromic materials that change color. As a result, they can improve comfort in homes and buildings while also contributing to energy savings. This technology is becoming increasingly popular in modern architecture and sustainable design.
