Both Sensible and Latent heat gains resulting from personnel room occupancy are accessed by clicking on the Personnel button. By clicking on the Add button menus are accessed where the type of personnel activity (and hence levels of heat gains) can be defined and also the numbers of personnel engaged in each activity.

Multiples of different personnel activities may be simultaneously selected by repeating clicking on the Add button. Similarly, by highlighting previously entered selections, clicking on the Delete button will remove from the calculation only the data corresponding to the highlighted selection.
