What is M&V?
Measurement and verification (M&V) determines the savings from an energy or water project by comparing measured use after the change with a baseline adjusted to the same conditions.
Where M&V is required
Savings someone else must accept need M&V: energy savings performance contracts and utility energy service contracts, utility incentive programs, green loans and internal capital approvals. Owners also use it simply to learn whether a fix worked.
IPMVP options and the savings equation
The International Performance Measurement and Verification Protocol is owned and maintained by the Efficiency Valuation Organization, and its current core document is IPMVP Core Concepts 2022. Options A and B isolate a retrofit, Option C uses meters on the energy supply to the whole facility, and Option D applies a calibrated simulation when baseline or reporting period data are unreliable or unavailable. Savings equal adjusted baseline use minus reporting period use, with non-routine adjustments for changes outside the project.
Where M&V sits in Aqueduct
Billing Management lists M&V as its third use after tenant billing and bill validation: once controls or optimizations are running, it shows whether savings happened. For whole-site claims, the baseline is a regression on usage and degree days. For a single RTU or chiller, Smart Controls baselines that equipment's power first and reports savings against it.
