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 volume flow rates required to ensure the desired indoor climate quality. Standard default values are provided for each of the categories, but you can adjust these as you wish.

Building Emission: Drop-down list for defining the global default setting for the pollutant load of the building in accordance with DIN EN 16789-1. The higher the pollutant load in a building, the greater the volume flow rates required to reliably dissipate or dilute the loads. Standard reference values are specified for each of the load levels, but you can adjust these if necessary.

Person-related Specific Outdoor Air Volume Flow Rate

Defines the global default setting for the specific outdoor air volume flow rate per person.

: One click restores the standard default value.

Building-related Specific Outdoor Air Volume Flow Rate

Defines the global default setting for the building-related specific outdoor air volume flow rate.

: One click restores the standard default value.

Room Settings

This table shows all rooms to which the calculation basis DIN EN 16798-1 Air Pollution, Method 1 is assigned and allows you to edit the room settings.

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.


Column	Description
et	Defines which rooms are edited together. Tick the rows of the rooms that you want to edit together and then change the desired parameters for one of the rooms. Clicking on the column header et activates or deactivates all rows.
Location	Shows the name and location of the room in the building structure. You can change the name if required.
Room Area	Displays the area of the room calculated from the clear internal dimensions.
Room Volume	Displays the volume of the room calculated from the clear internal dimensions.
Category	Defines the category for the quality of the indoor climate in accordance with DIN EN 15251. Settings that originate from the global default setting are marked with the addition From Project Setting:.
Building emission	Determines the pollutant load of the building according to DIN EN 16798-1. Settings that originate from the global default setting are marked with the addition From Project Setting:.
Qty. Pers.	Defines the number of people in the room. Values originating from the CAD program and changed values are shown in bold. If another calculation method with reference values for the number of persons is selected, the reference value of the other calculation method is adopted by removing the number of persons, as no reference values for the number of persons are calculated as part of method 1 of DIN 16798-1.
VspecP	Determines the personal specific fresh air volume flow of the room.
Vspec	Defines the building-related specific outdoor air volume flow rate of the room.
Vges	Displays the required total volume flow rate of the room. This value is transferred to the Air Volumes area as the result of the air volume determination.
