A home automation system let evolve and expand the function usually carried out by shutters, blinds and curtains. From simple elements which complete the exterior of a building and ensure privacy, these devices play an important role in order to improve a coordinated building management.
In the summer season they limit the solar radiation that go through the glass surfaces of doors and windows, thereby reducing the heat load to be removed by the air conditioning system. In winter they can work on the opposite, favoring the entry of free solar heat gains.
In combination with the information sent to the bus by a weather station, a home automation system brings in the safety position the shading systems when a storm is approaching, or selectively limits the direct solar radiation on only one side of the building, to avoid glare and increase the comfort in using personal computers and watching TV.
