In order to counteract summer overheating, the demand for cooling energy in buildings has rapidly increased in recent years. Well-designed external shading systems can minimize the need for cooling energy by up to 75 %. For this purpose, a thermosensitive actuator based on the thermal shape memory effect has been developed to regulate a shading system according to climate conditions. At the same time, user´s intervention is partially allowed, e.g. over the winter to provided demand-controlled glare shield, since overheat protection is not required.
