Within an Italian Experimental Programme an interdisciplinary research for the retrofitting of some residential buildings in the surrounding of Florence has been carried out. The activity of the experimental research concerns the methodological and scientific support to the technical solutions for the restoration of two buildings. The buildings typology with central gallery and single face dwellings is the cause of bad ventilation and poor indoor air quality (IAQ) in the rooms and, consequently, is the cause of other problems related with an insufficient air exchange rate: odours and vapours stagnation, vapours condensation on cold walls, etc. In this paper preliminary results concerning IAQ improvement by using suitable ventilation systems are reported and discussed.
