BIM Process for acoustic problems

Recent communications from the European Community oblige Member States to use the BIM (Buildilg Information Modeling) in the realization of public works. At European level countries like the United Kingdom, Sweden, Holland and Denmark have already used BIM models for the management of the built heritage for several years. At extra-European level China, the USA and in particular Singapore have long taken the road to digitization of buildings and more generally of the built heritage. What drives to digitalization is saving money that these digital procedures allow in the different phases of life of buildings. The present work wants to do an overview of the use of Open Source BIM models regarding the management of acoustic problems, both for the acoustic performance of buildings and from the point of view of environmental acoustics. In the work the main open source data formats available today, such as IFC and CityGML, some of which are recognized as standard from ISO. The data concerning the acoustic issues present in the various formats will also be analyzed and one Data Template will be proposed for the lack of parts or missing according to the provisions of the various international standards.
