The French company Arcora has developed a solar shading façade system with a shape memory alloy. When the alloy heats up, the system is able to set a translation carriage in motion. This carriage transmits the force to the rotating solar shading louvres via small connecting rods. This compact system can be used to replace standard motorisations in building façades, which are more susceptible to maintenance and repair, noisier and more susceptible to heat. For the interfaces between the moving (rotation, translation) and fixed elements, the designers were looking for suitable bearings that could withstand dust, the effects of the weather (in a double-skin façade, the temperature can reach up to 70°C in summer) and fluctuations in humidity.
