Define the Calculation Method for Determining the Air Volume

In the Project Standards area, define the Standard Calculation Method 1, which is then assigned to all room types as Calculation Method 1.

By Default, the Calculation Method DIN 1946-6 Domestic Ventilation (12-2019) is set for Residential Buildings, and for Non-Residential Buildings, DIN EN 16798-1 Air Load, Method 1 (03-2022) is set as Standard Calculation Method 1.

Define the Standard Calculation Method 2, which is then assigned to all room types and any exceptions created for rooms or room groups as Calculation Method 2.

If necessary, deactivate the Only show existing room types in the project checkbox to also assign calculation methods to room types that are not part of the current project.

If necessary, assign calculation methods that differ from the standard calculation methods to individual room types in the Calculation Method by Room Type area.

The Room Groups dialog opens.
