Introduction
This Measurement and Verification Plan has been prepared as a guide in determining the energy savings as a
result of the installed Energy Conservation Measures. In this document, EEI will show the baseline
calculations used to determine cost savings and how we can evaluate the installed measures to ensure the
Savings Guarantee is being satisfied.
EEI utilized the International Performance Measurement & Verification Protocol, 2002 Revision as a
technical reference for this document. In the Savings Measurement & Calculation section of this document,
EEI has prepared a spreadsheet that will be used to calculate and document savings throughout the guarantee
period. The M&V Options to be used are outlined in the Project Overview section of this document.
EEI will submit a Measurement & Verification Report to the customer twice annually throughout the
guarantee period.

or systems; engineering estimates, spot-, short-term, orlong-term
measurements of sy stem components; and long-term whole-building utility
meter data. Afterthe model has been calibrated, savings are determined by
comparing a simulation of the baseline witheithera simulation of the
performance period or actual utility data.
