Details on Occupants
Information on the Occupants dialog in the dynamic cooling load calculation.

Table
You can assign room-specific load profiles for occupants.
| Column | Description |
|---|---|
| Quantity | Number of lights/people/devices/air streams or mass flow rates to which this load is to apply. The load [W] is multiplied by the number. At room level, the number of people per square meter is automatically calculated for people from this specification. |
| Quantity per m2 | Number of occupants per square meter. When you enter this value, the value for Quantity is calculated automatically. |
| Usage profile sets | Displays the currently assigned usage profile set. Click |
| Name | Click If a template for dynamic capacity calculation according to VDI 2078 is selected to determine the occupant load, the cooling load within the selected activity level is calculated dynamically depending on the corresponding target temperature profile and the outside temperature. |
| Usage % | Percentage to which the selected profile set is used. This value is considered in addition to the usage values in the profile set. Accordingly, a profile of 50% with a usage of 50% is 25% effective. |
| B % | The load factor of room indicates what portion of the convective part of the internal load is effective in the room. Values <100% reduce the cooling load. |
| Dyn. capacity | Activated: The load is calculated dynamically, taking into account the specified activity level. If you selected dynamic load determination in the Name column, this option is automatically activated. If you activate this option manually, the activity level most recently displayed is adopted. |
| Degree of activity 1-4 | If you selected dynamic load determination in the Name column, the corresponding activity level is automatically entered. You can adjust it afterwards. |
| Load W | The capacity delivered by the internal load in the room. When entering this value, the value for the specific load will be determined automatically. |
| Convection % | Percentage of the load that is convected directly to the room air. The rest of the load acts radiatively on the enveloping surfaces present in the room. |
| Latent load W | Absolute load generated by evaporation in Watt. |
| Latent load/m2 W/m2 | Specific latent load per square meter in Watt. |
| Vapor output g/h | Emission of humidity into the air in grams per hour. These values are needed for the calculation of the humidity balance. |
