Application of BIM Model Checking in building acoustic design
No full textBuilding Information Modeling (BIM) is a process with an increasing diffusion in the construction market that leads to considerable savings in realization times and building management costs. Within the BIM methodology, a key role is played by Model Checking for the validation of the projects not only during the design stage, but also during all the phases of the building process. The control of geometric interferences in the Building Performance Modeling (BPM) can be easily applied in the evaluation of the acoustic performance of a building using standardized methods. The purpose of this paper is to analyse the information contained in BIM data structure that can be used to design or to evaluate compliance with acoustic classes or, in general, the acoustic performances of a building

No full textThe prediction models proposed by the standards of the EN ISO 12354 series represent the reference point for the evaluation of the acoustic performance of buildings. However, there are limits in the
applicability of the methods proposed by these standards when the building elements have particularities that make them not comparable with reference structures indicated for the calculation of the overall performance, in particular in the presence of additional layers. This work presents the results obtained through a participatory method of collecting and analyzing experimental data recently introduced in the technical standards. They allowed the development of optimized reference curves for different types of building elements representative of particular national construction techniques

No full textTHE ACOUSTIC PERFORMANCE OF WOODEN BUILDING STRUCTURES: WHAT COMES NEXT?
No full textThe wooden construction systems, particularly Cross Laminated Timber, have met with considerable success and established themselves as an alternative technology thanks to the great versatility of recently developed technical solutions. In this work, the results obtained in advanced research in building acoustics are reviewed, and the limits still existing in the knowledge of these building systems are highlighted
The contribution of cruise ships to the sound emission of a harbour
No full textIn recent years, the growth of cruise tourism has often been at the centre of controversy due to the environmental impact, especially for those harbours that, for historical and urban planning reasons, are in close contact with urban areas of particular value or under cultural heritage protection. The deadlock of cruise activities due to the COVID-19 pandemic emergency created the conditions for observing the effects of the substantial disappearance of a specific sound source from the harbours of many cities. This paper presents the evaluation of the contribution of large cruise ships to the overall noise emitted by a specialized cruise harbour and the consequences of their absence on the urban acoustic climate
