Details on the “Sales Premises” Area (Project Level)

Information on the Sales Premises section of the Ventilation module in LINEAR Building.

In this area, you define the global default settings for determining the required air volumes for rooms in non-residential buildings based on the calculation method VDI 2082 Sales Premises. In this section you will also find an overview of all rooms assigned to this calculation method, including their settings. You can edit the room settings in the overview on a room-by-room and multi-room basis.

“Sales Premises” area of the Ventilation concepts module in LINEAR Building.

Method

Method: Drop-down list for defining the global default setting for the method for determining the required air volumes.

The following methods are available:

Selection of Minimum Outdoor Air Volume Flow Rate

This method uses the Specific Minimum Outdoor Air Volume Flow Rate and provides you with the categories Category II: Normal Level of Expectations and Category III: Moderate Level of Expectations for the quality of the indoor climate. With regard to Building Emissions, only low-emission buildings are supported.
Calculation of Minimum Outdoor Air Volume Flow Rate

This method uses the specific volume flow rates per person and area and provides you with all the options for the expectations of indoor climate quality and building emissions.

Category: Drop-down list for defining the global default setting for the expectations for the quality of the indoor climate. All four categories are available for the Minimum Outdoor Air Volume Flow Calculation method. Only categories II and III are available for the Minimum Outdoor Air Volume Flow Rate Selection method. The higher the expectations, the greater the specific volume flow rates required (per person and area) to ensure the desired indoor climate quality.

Building Emission: Drop-down list for defining the global default setting for the building's pollutant load. All three levels are available to you when calculating the Minimum Outdoor Air Volume Flow Rate. For the method Minimum Outdoor Air Volume Flow Rate Selection, only the Low-Emission Building level is available. The higher the pollutant load of a building, the greater the specific volume flow rate per area VspecA required to reliably dissipate the loads.

Room Settings

This table shows all rooms to which the VDI 2082 Sales Premises calculation method is assigned and allows you to edit the room settings. You can edit the settings of several rooms together by checking the et column in the rows of the rooms to be edited together.
