Begin with the unresolved questions
Identify which system, tenancy, process or operating period needs better visibility and what action the data should support. A main bill can show total cost while hiding a compressed-air problem, an out-of-hours load or a difference between sites. Sub-metering is useful when it closes a specific evidence gap.
Map existing meters, electrical boundaries and accessible data first. Then agree measurement points, sampling frequency, retention and who will review the results. Use appropriately qualified people for design and installation, and consider safety, communications and maintenance alongside the purchase price.
Make the data trustworthy and used
Check meter labels, units, time zones and totals against a known reference before drawing conclusions. Reconcile sub-meter totals with the main meter where the arrangement allows, and investigate gaps rather than silently estimating them. Give every dashboard a defined audience and purpose.
Start with a small set of actionable views: after-hours use, peak demand, system runtime or energy per unit of activity. Assign alerts and routine review to a named owner. If nobody acts on a measurement, reconsider whether it belongs in the initial scope.
- Tie every proposed meter to a decision.
- Map existing metering and site boundaries.
- Plan safe installation and ongoing maintenance.
- Validate units, timestamps and missing data.
- Assign review, alerts and follow-up ownership.
Common questions
Does more metering automatically reduce energy use?
No. Savings come from decisions and action; metering improves evidence when it is reliable and reviewed.
Can temporary measurement be useful?
Yes. Australian Government guidance notes that rented meters can capture short-term use where permanent metering is not necessary.
