In European cities, where urban historical assets are highly regarded, heavy rehabilitation has proved popular so as to optimize the effective floor area and the function of buildings without hampering the architectural and urban development trend. Such a move also aims to comply with the urban bylaws as regards maximal admissible values of building height and capacity. This paper aims at giving a picture of the noise control engineering aspects of such operations through a few case studies. This will entail a brief look at applicable regulations, as well as a sobering look at diagnosis difficulties. Prescriptions and eventual commissioning will then be examined. One of the key conclusions drawn from experience is that the diagnosis and the prescriptions should never be carried out by the sole noise control engineer, as they often constitute a compromise between the various constraints.
