About Ventilation Data
Explains the concept Ventilation data in relation to the heat load calculation.
The selection of the ventilation system has a direct influence on the heat load. At the project level, you can make some default settings and specify them on the room level or define them differently from the project settings, if necessary.
If different ventilation systems are selected in the individual rooms, the display of the ventilation system on the project level depends on which system is most frequently used in the rooms.
