The aeration, as defined by the UNI EN 12792, is a change of air by “windows opening”.

Depending on the habits it could involve: energy wasting, cold air in winter and too hot air in summer, lack of inlet air control with possible pollutants, possible increase in noise in the environment, nuisances caused by air flow.

Another thing is the natural ventilation, which is the ventilation obtained by infiltrations and openings of buildings that, thanks to the difference in pressure between the external environment and the internal space allows the passage and the exchange of air.
