As the design of the shading system considers the use of shape memory alloys (SMA) as micro-actuators to accomplish solar adaptation, Origami pattern has been adopted to guarantee a relatively large displacement of the shading system with a small deformation of the SMA wires actuators. Thanks to this shape change, generating overlapped pleats and angle variation and using different materials, it has been possible to provide alterations of the direct light transmission inside the building while maintaining a certain degree of diffuse light component.
