This research explores using advanced smart materials to upgrade existing buildings, making them adapt naturally to their surroundings for better comfort without needing people to adjust settings. By integrating these smart materials in different geometric patterns on the building's outer layer, they can optimize the indoor environment by managing temperature, lighting, and overall comfort. This innovative approach benefits both occupants and the building itself, reducing energy consumption and costs. Case studies from around the world have informed this method, with local adaptations showcasing the effectiveness of these smart materials on existing structures. The key findings emphasize the practical potential of integrating smart materials into building facades to create more responsive, energy-efficient, and comfortable spaces.
