Noise from plant systems and Building Information Modeling : The Code Checking

The acoustic performance of buildings is increasingly a performance requirement required both in the construction of private buildings and public buildings. At international level, in recent years we have witnessed the revision and issue of new standards relating to the project phase (forecast calculation) of passive requirements based on the ISO 12354 series of standards. At the plant design level, the reference standard is represented by EN 12354-5 and ISO 16032 while in the post-operation verification phase the ISO 16032 and ISO 10052 standards are the reference for the measurements. One of the fundamental aspects to achieve high performance is to reach a level of design study that is increasingly detailed and shareable. Building information modeling, in addition to being an obligation for some types of work, is increasingly used by designers and construction companies, to have a better knowledge of the case on particular and methods of execution. The present work presents an overview of procedures that exploit the information of the BIM model for the predictive calculation of the acoustic performances of the systems, the verification of the legislative limits and the integration of the instrumental data recorded post-operam. The procedures were finally tested on a case study.
