As of the 2017.c version, CYPESOUND and its specific versions for some countries, import, from a BIM model, the noise produced by the openings of ventilation systems. Users then had to specify the other properties that specify the noise produced by these openings in a precinct.
As of the 2017.e version, CYPESOUND, CYPESOUND CTE (Spain), CYPESOUND RRAE (Portugal), CYPESOUND NRA (France) and CYPESOUND DRAPDE (Italy), automatically calculate the following parameters: “r” (radius of the largest sphere that can be inscribed in the precinct) and “D” (directivity factor of the source) of the grilles and diffusers. This way, the noise generated by the HVAC duct networks in the precincts can be obtained more easily.
The analysis is carried out during the import process of these elements, based on IFC files, hence the CYPESOUND project must import them from the BIM model (either because the project is linked to a BIM model or, if it is not, because the BIM model has been imported without maintaining the link). Logically, the imported BIM model must include the design of the duct installation for heating, ventilation and air conditioning. CYPETHERM HVAC allows users to export these installations to the BIM model.
