The Energy Smart Industrial (ESI) program uses a Monitoring, Targeting, and Reporting (MT&R) methodology—in conjunction with a process to track specific activities—to estimate energy savings for Strategic Energy Management (SEM) projects. This document outlines recommended methodologies to 1) establish baseline energy models at a whole-facility or subsystem level, and 2) quantify energy savings associated with the implementation of multiple energy efficiency measures (EEMs) over a defined performance period.
