Harbor Office Weekly Energy Use

Harbor Office tracks weekly electricity use against a simple consumption target. The line graph makes it clear that the first two weeks exceeded the target and that use fell below it later in the period. A facilities team can use this view to start a practical conversation about weather, occupancy, operating hours and equipment changes. The graph should be based on consistent meter readings and a stated site boundary; adding another building midway through the period would make the trend misleading. Electricity use alone does not equal emissions, because the emissions factor may vary by supplier and location. For an energy report, keep that calculation separate. Add annotations for known events, such as HVAC maintenance, when they explain a visible change in the series.

CASE ANALYSIS

Scenario

Office energy-management review.

Key decisions

  • Use metered data: retain a consistent site boundary.
  • Compare with target: the reference line makes progress visible.
  • Investigate anomalies: week two needs context before action.

When to reuse this

Use for one facility’s recurring energy measure and an agreed target.

FAQ

Frequently asked questions

Why include a target line?01
It gives readers a fixed reference for judging each week’s use.
What unit should I use?02
Use the meter’s consistent energy unit, such as kilowatt-hours.
Can weather affect the line?03
Yes. Temperature and occupancy should be considered when interpreting changes.
