Acoustic Insulation And Building Information Modeling: A Model Of Calculation For The Code Checking In The Forecast Phase And Of Measurement Of Performance

The acoustic performance is more and more often a requirement in the construction of both private buildings and public buildings. Internationally, over the last few years we have witnessed the revision and issue of new standards relating to the project phase (calculation of the performance) based on the ISO 12354 series, and the post-building verification phase based on ISO 16283 standards. Fundamental aspects to achieve high performance consist of achieving a level of details that is increasingly high and shareable. Building information modeling, in addition to being mandatory for some types of work, is increasingly used by designers and construction companies, to gain greater knowledge of the specific case in particular and of methods of execution. In the present work a calculation code is presented which, taking advantage of the BIM model information, allows the calculation of the performance, the check of the legislative limits and the integration of the post-building data instrumentally recorded. Finally the code was tested on the considered case study and monitored in the different building phases.
