Objective/Method/Outcome
Objective: Determines if the zone is constantly in occupied mode
Method: Checks if the zone was occupied for more than the acceptable amount of time and calculate the potential savings by reducing excessive occupancy avoidable cost
Outcome: Triggers an insight and calculates excess hours of occupancy
Description
Checks occupancy trend, and generates an insight if the trend is enabled for more than 160 hours in a week. Also calculates excess hours of occupancy using a threshold of acceptable hours of daily occupancy.
This rule is part of the CopperTree Standard ruleset.
Default Priority
Low
Diagnosis
- Review occupancy sensor calibration.
- Ensure occupancy point is configured correctly.
Message
The zone is consistently in Occupied Mode.
