Measurement and verification that proves a saving happened, measure by measure.
M&V answers one question: did the change you made save what it promised? Aqueduct compares metered use after a measure with the weather-normalized baseline from before it, and checks command history to confirm the measure actually ran.
Before, after, adjusted for weather, with proof the change ran.
How a saving is verified
- A dated measure
Each change, such as a new schedule or a repaired economizer, is logged with its start date and the meters it affects.
- Avoided use
Expected use from the baseline minus metered use after the change, summed over the reporting period.
- Proof the measure ran
For control measures, command history shows which commands executed on the device, not only that they were sent.
Reports finance and auditors can check
- Savings in units and money
Avoided kWh, therms or gallons, priced with the site's own tariff.
- Bill validation
Supplier bills compared with your own meter data, so you pay for what you used.
- Persistence
Savings tracked month after month, so a measure that slips back is caught.
Why claimed savings need proof.
of the energy used in commercial buildings and industrial plants is often wasted.

Illustrative: a hospital adds occupancy schedules to 12 air handlers in March. By June, metered use on those feeders is below the weather-adjusted baseline, command history shows the schedules executing daily, and the avoided kWh are priced at the hospital's tariff.
Limits
Aqueduct verifies at the whole-meter or sub-meter level, the metered approach IPMVP calls Options B and C. It does not certify savings; a third-party verifier signs off where a program requires it.
Several measures on one meter at once cannot be separated without sub-metering or staggered start dates. Non-routine changes, such as a new tenant, need a documented adjustment.

Common questions
No. Baselining builds expected use for a site. Aqueduct M&V applies that baseline to one dated measure and reporting period, then adds proof from command history that the measure actually ran on the equipment. See weather-normalized baselining.
Yes. Aqueduct supplies the metered evidence an energy savings performance contract needs: baseline, avoided use per measure and proof the measure ran. Contract terms, adjustments and sign-off stay with the owner and the ESCO. See ESPC and UESC contracts.
Aqueduct compares each supplier bill with your own meter readings for the same period. A gap between billed and metered use, or a rate that changed, shows up as an anomaly to dispute before payment. See utility bill validation.
Aqueduct uses whole-facility or metered-equipment comparisons against a regression baseline, which match IPMVP Options C and B. The project M&V plan states which option applies to each measure. See IPMVP.
