Details on Individuals, Lighting and Machinery

Information on the Individuals, Lighting and Machinery in the Edit room groups section.

Here, for the rooms in the selected room groups in each case, you can create and parameterize internal loads for persons, lighting and machinery. The settings can be adjusted at room level.

Persons

Column

Description

Entries in

Number of rooms of the selected room group for which an internal person-related load applies. If you create an internal load and then add a further room to the room group, the internal load doesn’t apply to the room added subsequently. This column is identical for all types of internal loads.

Quantity

Number of persons present in the rooms of the selected room group.

Number per m²

Number of individuals per square meter in the rooms of the selected room group. The number of persons is determined for each room individually, dependent on the room size.

Attendance time

Drop-down list for selecting the times when the specified individuals are present in the rooms of the selected room group.

Level of activity

Drop-down list to select the activity level of the persons. The higher the activity level, the higher the heat input from individuals and the internal load.

Lighting

Column

Description

Total lighting capacity

Total lighting capacity of the internal load in watts.

Lighting output W/ m²

Lighting capacity per square meter from the internal load. If you populate this field, the Total lighting capacity field is set to zero. The absolute lighting capacity is determined for each room individually, dependent on the room size.

Simultaneity factor

Factor for the simultaneity of the lighting activity.

Runtime

Dropdown list for selecting the period in which the lighting is on.

Convective part

Part of the internal load that is output as a convection directly to the air in the room inside the set operating time.

Exhaust

Dropdown list for selecting the type of extraction. If an extraction system is selected, the program calculates a corresponding room load level dependent on the air throughput.

Air throughput

Air exchange that is set on the basis of the set extraction in the room per unit time.

Load level

If an extraction system is selected, a load level from VDI 2078 Table A4 is set automatically.

Machinery

Column

Description

Total machinery power

Total output from machinery for this internal load.

Machinery power W/m²

Capacity per square meter from machinery. If you populate this field, the Total machinery power field is set to zero. At room level, the actual machinery capacity is calculated individually, dependent on the room size.

Rated power (shaft power)

The rated power of the machinery in the selected room group.

average motor efficiency

The average motor efficiency of the machinery in the selected room group.

Load level

The load level is set based on the internal load in the selected room group.

Simultaneity factor

Factor for the simultaneity of the machinery output.

Runtime

Dropdown list for selecting the period in which the machinery is in operation.

Convective part

Part of the internal load that is output as a convection directly to the air in the room inside the set operating time.
