The ‘IFC4AcousticParser Service’ implemented as part of BIM-SPEED project is developed with the need for the objectives set by the BIM-SPEED Project. It helps in:

• Reduced time and improved accuracy of results in renovation projects compared to traditional methods, as no user iteration is required to obtain the necessary data (only for the correct generation of the IFC file used as input) and calculations are performed with precise geometric operations and calculations.

Retrieve automatically the data needed by the Acoustic Comfort tool from an IFC file to obtain the acoustic assessment of a building, in order to know the acoustic class of the building in the design phase of the building renovation.

The comparison between the conventional practices for obtaining the acoustic assessment of a building, using a specific Acoustic Comfort tool, with the use of the BIM‑SPEED solution (Ifc4Acoustic parser server) is shown in the image below:

The tool needs as input an IFC that complies with the input requirements defined in the tool, if this is not the case, the results will not be valid.
