In this area, you configure the room-specific settings for determining the required air volumes for rooms in non-residential buildings based on the calculation method DIN 1946-7 Laboratories (08-2022).

General Room Data
The room number, the room name and the room temperature for the heating or cooling mode are displayed on the left-hand side, which you can adjust as required. Depending on the module, you can use the button 
to the right of the room temperature to open the Temperatures dialog, in which you can select the temperature variables stored in the master tables and create new temperature variables.
The area resulting from the clear internal dimensions and the clear internal dimensions of the room are displayed in brackets in the right-hand area.
: Opens the Room Data dialog in which you can adjust the parameters of the room.
Minimum Volume Flow Rate
Room Type according to DIN 1946-7: Drop-down list for selecting the room type according to DIN 1946-7. Standard-compliant default values for the methods specified in the standard are stored for each room type, which you can adapt as you wish. You can also, for example, enter values for area-related minimum volume flow rates or specify a fixed minimum volume flow rate for room types whose required air volumes are described in the standard with minimum air exchange rates. The air volume flow rate with the highest value is then used as the required air volume. The results of the individual procedures are displayed on the Results tab.
Minimum Air Exchange Rate
Defines the value for determining the required air volumes on the basis of minimum air exchange rates. Clicking on 
restores the default value if a default value is stored for this parameter for the selected room type.
Minimum Volume Flow Rate
Defines the minimum volume flow rate for the room. Clicking on restores the default value if a default value is stored for this parameter for the selected room type.
Minimum Volume Flow Flow Rate per Area
Defines the value for determining the required air volumes based on the area-related minimum volume flow rate. Clicking on restores the default value if a default value is stored for this parameter for the selected room type.
