Imagine waking up on a sunny morning and watching your bedroom windows automatically become darker to reduce the sunlight entering the room. Later, when the weather gets colder, they become transparent again to let natural light and warmth inside. This may sound like something from a science-fiction movie, but smart window technology is already a real area of innovation. Unlike traditional windows, smart windows can change their appearance or light transmission based on electrical signals, temperature, or environmental conditions. And the interesting part is that they could eventually become an important component of energy-efficient buildings. What Exactly Are Smart Windows? Smart windows are specially designed glass systems that can control how much light, heat, or glare passes through them. Some models use electrical technology to change their transparency, while others respond to temperature or sunlight. One popular category is electrochromic glass. It uses a small electric...
