occupancy (eg 50% occupied in 8h time) vs utilization (2 out of 4 chairs)
e.g. a room can be occupied 50% of a day (4 out of 8h) but when only 2 chairs are used out of 4,
it is utilized 50% against 50% occupation.
-> 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%
Direct Utilization & Occupancy
| Sensor method | Installation method | other hardware needed | max installation height | Functioning method | max Detection area | Icon decay | Config | info available | advised for utilization? |
|---|---|---|---|---|---|---|---|---|---|
| Pointgrab | wired | none | 2.15m (7ft) to 4.5m (14.8ft) | https://confluence.mcs.be/display/SUM/Headcount+%28Pointgrab%29+Sensor+way+of+measuring | 8m x 6m (26 x 20 ft) | 2min | CPMS + Studio | Live Floorplan+Dashboards | yes for utilization in meeting rooms or in open spaces |
| Vergesense wired | wired | device manager | 3,66m (12 ft) | Every 1min, a snapshot is taken + data is updated every 1 min; intervall is so low that person in the room will be captured | 1 per room or ~ 6 desks (smaller detection area than Pointgrab) | 2min | Vergesense + Studio | Live Floorplan+Dashboards | yes for utilization in meeting rooms or in open spaces |
| Vergesense wireless | wireless | gateway+wireless repeater | 3,66m (12 ft) | Every 15min, a snapshot is taken (no average of 15min!) and data is send to Cobundu Cloud every 15min. | 1 per room or ~ 6 desks (smaller detection area than Pointgrab) | 15min | Vergesense + Studio | Live Floorplan+Dashboards | yes for utilization in meeting rooms or in open spaces |

Indirect Utilization & Occupancy
...
- Occupancy
- Presence on room level is true in case presence is true for 1 or more workplaces OR if presence is true for the sensor linked to the room itself
- So if someone walks around in the room, where workplace PIRs are not triggered, but room PIR is triggered -> presence = true
- Utilization
- If presence detected on workplaces level AND room level, headcount will only be calculated based upon sum of triggered workplaces. It ignores the room PIR.
- So if 2 people sit on a chair triggered by workplace PIR, headcount will be 2
- If presence detected ONLY on room level and not on workplaces, headcount is set to minimum 1
- So if someone walks around in the room, but workplace PIRs not triggered, headcount is 1
Example
Quarter 1 | Quarter 2 | Quarter 3 | ||
Occupancy | Room PIR | 0 | 1 | 1 |
Wp 1 PIR | 1 | 1 | 0 | |
Wp 2 PIR | 1 | 1 | 0 | |
Wp 3 PIR | 0 | 0 | 0 | |
Room occupancy live floorplan | TRUE | TRUE | TRUE | |
Room utilization live floorplan | 2 | 2 | 1 | |
Room utilization count timeslots | 2 | 2 | 1 |
Utilization & Occupancy on Life Floorplan
Occupancy on live floorplan shows: occupied or not (independent of how many people there are)
Utilization on live floorplan shows: how many people are detected there
