On the use open BIM procedures for acoustic problems of the buildings: the new IDS standard for design stage and verification stage

Recent European directives provide for the use of digital procedures based on Building Information Modeling (BIM) as a tool for the design and management of the entire life cycle of public buildings. This directive has been implemented by the various Member States. Even acoustic performance must now be evaluated with the use of digital procedures based on BIM. The purpose of this work is to analyze the standards currently available on the market for the Desing phase, the verification phase and the acoustic classification of the buildings and evaluate the applicability through the use of the Open BIM models is the format and specifications based on IDS format. An Information Delivery Specification (IdS) is a computer interpretable document that defines the Exchange Requirements of model based exchange. This can be a combination of Industry Foundation Classes (IFC), Domain Extensions, and additional classifications and properties (national agreements or company specific ones; either stored in bSDD or somewhere else).
