Energy Efficiency Program Impact Evaluation Guide

December 20, 2012

The key efficiency evaluation, measurement, and verification resource for novices and experts. Includes definitions, concepts, and steps for calculating savings, avoided emissions, and other impacts.

  • This document was a very useful resource for the Public Utility Commission of Texas (PUCT)—specifically Section 5 on determining net savings. It provided the information we needed and supported our EM&V team's approach for treating common and tricky issues such as free ridership, participant spillover, and net-to-gross calculation determinations.
