In recent years, the frequent summer heat waves have led to a widespread use of air conditioning, but this had a big impact on the energy consumption of buildings and the emissions of polluting and climate-altering gases. In this case domotics can give a considerable help to mitigate the negative effects of this trend.
On one hand, it provides many opportunities in order to optimize the operation of the installation: they include daily or weekly time scheduling, the independent control of zones or rooms, the attenuation manual or automatic of temperature, the remote switching or control and more useful information to users.
Secondly, and more importantly, home automation allows to manage the air conditioning in a coordinated way with the rest of the building installation. For example, lowering shutters or inclining external venetian blinds greatly reduces the solar radiation that enters the room through the glass surfaces of doors and windows. Consequently the heat load to be removed is lower and with it the need of conditioning power.
