Abstract: Interactive facade technology is a way of designing building envelopes which can change their properties or form in response to various environmental stimuli like temperature, humidity, solar radiation, etc. The objective of this study is to develop a kinetic facade shading device inspired by the principle behind plant movements in nature, to analyse the potential of the system for its practical applications in facades and to examine the factors which determine the efficiency of shading device. The hinge-less bending deformation property of plants is translated into a kinetic shading device, featuring curve line folding mechanism, using flexible polymers. The designed component is tested using ANSYS static structural analysis. The application of verified component in building facades of different geometries is demonstrated using physical paper models and digital models. Further, the possibility of applying the principles of leaf rolling mechanisms in nature to design solar responsive actuator is demonstrated using smart materials.
Keywords: adaptive facade shading, biomimetics, curve-line folding, flexible polymers, shape memory alloys
