The goal of this project is to design and realize a new type of autoadaptive and dynamic façade system, actuated and controlled passively by thermal expansion. This system respond to changing environmental conditions for guarantee the optimal internal comfort conditions to the occupants, without utilization of motorized means to move and control the various parts. The method proposed takes advantage of unique thermodynamic properties of materials, namely thermal expansion, to induce motion. The position of the sun in the sky, the air temperature, the weather conditions and the wind speed drives the differences of temperature between some parts of the system. Therefore the different thermal expansion between the parts caused by the temperature differences induce mechanical motion to the system.
