This project explores a heat-sensitive architectural adaptive façade, actuated using shape memory alloys (SMAs). A geometrical origami component and a corresponding facade composition was designed to optimize the adaptability of the system. Three types of actuation systems were investigated: passive (heating –UV), cooling (by two-way treatment), electrical (Arduino circuit heating), and mechanical (using springs/weights) for shape recovery. A physical prototype was fabricated and tested for straight and spring SMAs for movement actuation and user-override mechanism.
