VERIFY THE NET RESULT
Agree the method before the operating state changes
Energy savings are avoided consumption, not a directly metered commodity. A credible M&V plan defines the boundary, baseline, variables, adjustments, test method, reporting period and uncertainty before commissioning.
Choose the method for the decision
A controlled ON/OFF test can be powerful when operating conditions are stable and the change can be isolated. A whole-facility interval model may be better where weather, production, occupancy or trading conditions vary. An engineering calculation may support screening or component-level analysis. The selected method should be proportionate to the claim and risk.
Minimum M&V content
- Measurement boundary and included/excluded loads
- Baseline and reporting periods
- Metering, accuracy, calibration and time synchronisation
- Independent variables and routine adjustments
- Non-routine event process
- Optimiser losses and net/gross treatment
- Tariff and cost-conversion method
- Uncertainty, data gaps and quality checks
- Reporting frequency, review and approval responsibilities
IPMVP and independent review
Where appropriate, the project can use the current International Performance Measurement and Verification Protocol as a recognised framework. The chosen option does not make a weak baseline strong; the plan and data still need to suit the facility and decision.
Reporting beyond energy
Demand, cost, emissions, asset and operational outcomes should be reported as separate quantities with their own boundaries and evidence. Climate, ESG or NABERS-related use should follow the organisation's applicable rules and assurance process.
