Zone consistently in occupied mode

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

  1. Review occupancy sensor calibration.
  2. Ensure occupancy point is configured correctly.

Message

The zone is consistently in Occupied Mode.
