The configuration of the acoustic index that is used to measure noise generated by the equipment of the building has been included in the design options, amongst the general parameters of the project. Users can select one of the following global sound pressure level indices:
- LA: Sound pressure level in a space, [dBA]
- LnA: Normalized sound pressure level in a space, [dBA]
- LnAT: Standardized sound pressure level in space, [dBA]
Furthermore, users can indicate how the absorption of the emitter space is to be calculated. This can be carried out in the design options panel or in each space of the project. If it is carried out in the latter manner, it will prevail over what is indicated in the design options. Users can choose one of the following alternatives:
- T = T0 = 0.5s (A = 0.16•V/T0)
- A = A0 = 10m2
- Use real absorption
