International Performance Measurement and Verification Protocol, Vol. 1 - 2010
The International Performance Measurement and Verification Protocol (IPMVP) Volume I is a guidance document describing common practice in measuring, computing and reporting savings achieved by energy or water efficiency projects at end user facilities.

The IPMVP presents a framework and four measurement and verification (M&V) Options for transparently, reliably and consistently reporting a project's savings. M&V activities include site surveys, metering of energy or water flow(s), monitoring of independent variable(s), calculation, and reporting. The IPMVP is intended to be used by professionals as a basis for preparing savings reports, in consideration of the unique characteristics of the project. Adherence with the IPMVP requires preparation of a project specific M&V Plan that is consistent with IPMVP terminology. It must name the IPMVP Option(s) to be used; metering, monitoring, and analysis methods to be used; quality assurance procedures to be followed; and person(s) responsible for the M&V.
