Yanzi Networks Installation Manual – Smart Office 7 of 19
2.2 Use Cases
Depending on which use case to cover, the type and position of sensors may vary. Two typical use cases
are shown below for space utilization and comfortability.
2.2.1 Space Utilization
For space utilization, Yanzi Motion/Presence sensors are added under the table at each work desk chair
and at each chair of larger conference rooms (typically rooms with 6 chairs or more) to detect usage. For
room usage, Yanzi Motion/Presence or Yanzi Motion+ is placed on the wall (rooms larger than 20m
2
are
recommended to use two sensors to make sure the whole room is covered). Selection between
Motion/Presence sensor and Motion+ sensor depends on if comfortability use case also should be covered
as the Motion+ sensor monitors more things than the Motion/Presence sensor.
Motion/Presence sensors may also be used for restroom utilization to monitor each stall as well as the
washroom.
Footfall cameras may be placed in the ceiling of each entrance to the building and can as well be placed
at the entrance to any area where specific information is wanted. The footfall cameras are connected to
the Gateway using Ethernet/PoE. This proposal do not focus on footfall cameras.
2.2.2 Comfortability
For comfortability, the work environment is monitored using for example CO
2
, temperature, humidity,
barometric pressure, volatile organic compounds (VOC), ambient light and ambient noise sensors. Yanzi
Comfort sensors are placed in each room (conference room, phone booths, locker room, etc.) where
people are present for longer periods of time as well spread out in open work spaces. In open work
spaces, recommendation is to use one Yanzi Comfort for each 15-25 work desks.
Yanzi Motion+ are used to monitor occupancy and light at work desks (preferably placed in the ceiling
where it covers about 6-8 work desks depending on height of ceiling). It is also used to monitor
utilization of smaller rooms such as conference rooms, phone booths, locker rooms, storage rooms,
kitchens, restrooms, etc.
