A strategy for sustainable acoustic classification scheme of dwellings

Abstract

The new legislation in Serbia for sound insulation in buildings, currently in preparation, should introduce for the first time a national implementation of dwellings’ acoustic classification. There are some structural systems and building typology that are common in existing housing stock. Some of them are caused by seismic demands and some by architects’ routines. All that introduced realistically accessible range of apparent sound reduction index values at different positions in existing buildings. To achieve a sustainable classification scheme in prepared new legislation the analysis of sound insulation in existing buildings were performed and implications of possible boundary values between different classes on the housing stock acoustic score were analyzed. Based on such approach, the suggestions concerned with the classification scheme and class limits are presented.
