A new option has been added in the general parameters of AcoubatBIM by CYPE where users can configure the way insulation against outdoor airborne noise is to be verified. As well as the individual analysis of each façade that has been carried out up to now, it is now possible to combine all the external façades and check the insulation of the complete envelope of each space. The program also allows users to group adjacent walls that share the same orientation and determine the insulation of these combined elements. Lastly, the enclosures can be grouped depending on their type (façade, roof or overhang) and calculate each separator group.
