Details on “Air Pollution Proc. 2” (Room Level)

In this area, you define the room-specific settings for determining the required air volumes for rooms in non-residential buildings based on the calculation method DIN EN 16798-1 Air Pollution, Procedure 2.

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.

General

Category: Drop-down list for selecting the category of expectations for the quality of the indoor climate in accordance with DIN EN 15251. The higher the expectations, the greater the specific volume flow rates required to ensure the desired indoor climate quality. If the category was taken from the global default settings at project level, it is flagged with From Project Setting:.

Ventilation Efficiency

Defines the factor for the ventilation efficiency of the air duct system. This parameter provides information on the efficiency of material load dissipation. The ventilation efficiency depends on various design aspects and can change depending on the temperature, the air volume flow, the air distribution and the thermal loads. The default value is 1, as the standard requires a factor of 1 in this respect without individual project planning.

: Resets changed values to a factor of 1.

Contaminations for Procedure 2

In this table, you define the contaminants in the room. Click in an empty row or press F5 to add more contaminants. After defining the limit value for the material, the emission of the material and the concentration of the material in the supply air, the outdoor air flow rate required to comply with the limit value is displayed in the Q_h column. Press F6 to delete entries from the table. The mandatory CO2 entry cannot be deleted.

By clicking you have the possibility to copy the contents of the table with or without column heading and paste it into Excel.

If you have selected individual rows or cells, you can copy the selected data with the key combinations Ctrl+C (with column heading) or Ctrl+Shift+C (without column heading) and paste it into Excel, for example.
