-> The real performance is then only 25% (half a day used for half the capacity).
Other example: An 8h meeting for 2 people in a meeting room with capacity=10
Occupancy = 100%
Utilisation = 20%

*How is utilization calculated in case both a room and workplaces are linked to a PIR sensor?
- Occupancy
- Presence on room level is true in case presence is true for 1 or more seats OR if presence is true for the sensor linked to the room itself
- So if someone walks around in the room, where seat PIRs are not triggered, but room PIR is triggered -> presence = true
- Utilization
- If presence detected on seat level AND room level, headcount will only be calculated based upon sum of triggered seats. It ignores the room PIR.
- So if 2 people sit on a chair/seat triggered by workplace PIR, headcount will be 2
- If presence detected ONLY on room level and not on seats, headcount is set to minimum 1
- So if someone walks around in the room, but seats PIRs not triggered, headcount is 1

Seat 1 PIR | 1 | 1 | 0 | |||
Seat 2 PIR | 1 | 1 | 0 | |||
Seat 3 PIR | 0 | 0 | 0 | |||

Utilization & Occupancy on Live Floorplan
Occupancy on live floorplan shows: location occupied or not (independent of how many people are in that location)
Utilization on live floorplan shows: how many people are detected in that location
