Medium term

The implementation of solar shading devices on windows is the most effective way to reduce the thermal contributions on facades exposed to the direct solar radiation. Type of shading device depends on the orientation of facades ; Protections are rather blackout type for facing east and west windows to raising solar radiations, and to overhanging type for the facing north windows. The protection panels should be designed with the best implementation efficiency by the architects to get the best protection (in case of Greenfield project). No need to cover all the facades of the buiding.
