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.

“Create a line graph for Harbor Office weekly electricity use in kWh: 1,280, 1,340, 1,250, 1,190, 1,160 and 1,120 from week 1 to week 6, with a weekly target of 1,200 kWh.”

接著試試Add a note for the HVAC maintenance in week 4.Change the target to 1,150 kWh.

這張圖裡有什麼

看懂背後的決策。

01Use metered data

retain a consistent site boundary.

02Compare with target

the reference line makes progress visible.

03Investigate anomalies

week two needs context before action.

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

常見問題

Why include a target line?

It gives readers a fixed reference for judging each week’s use.

What unit should I use?

Use the meter’s consistent energy unit, such as kilowatt-hours.

Can weather affect the line?

Yes. Temperature and occupancy should be considered when interpreting changes.
