In an exciting breakthrough in materials science, researchers have developed a chameleon-inspired coating that can cool buildings during hot seasons. This new coating is made with a combination of materials that can be applied to the outer walls of buildings, and it can cool the building surface by up to 10°C. It works by reflecting sunlight away from the building, while also allowing water vapor to escape from the surface. The coating also has a kind of “memory,” allowing it to automatically adjust the reflection of sunlight depending on the season and the amount of heat the building is receiving. This could be a game-changer for buildings in hot climates, as it could reduce energy costs and help keep the building comfortable in the hottest months.
