Acoustic and energy characterization of buildings with the use of BIM

The acoustic characterization of buildings combined with energy performance represents in some countries of the European Union such as Italy a legal obligation. The Italian state, for public buildings, also obliges to comply with the minimum environmental criteria (CAM). These provide for the new buildings or existing buildings subject to total renovation a minimum performance level corresponding to class two according to UNI 11367 standard. In addition, the transposition of the European directives introduced the obligation to use the BIM for public works on the national territory. This work analyzes digital procedures based on the BIM model to characterize buildings from an acoustic and energy point of view through instrumental investigations.
