Estimating Net Savings Under the Uniform Methods Project

Navigant co-authors an updated protocol for the US Department of Energy to help stakeholders compare methods for calculating savings in energy efficiency programs

Under the Uniform Methods Project (UMP), the U.S. Department of Energy (DOE) is developing a set of protocols for determining savings from energy efficiency measures and programs. The protocols provide a straightforward method for evaluating energy savings for residential, commercial, and industrial measures commonly offered in U.S. ratepayer-funded programs.

Navigant’s Dan Violette, managing director, recently assisted the DOE with an update to one of its protocols on Estimating Net Savings — Common Practices. The document focuses on the methods used to estimate net energy savings in evaluation, measurement, and verification studies for energy efficiency programs. Unlike other UMP resources that provide recommended protocols for determining gross energy savings, this document describes and compares the current industry practices for determining net energy savings.

The intent of the document is to present information on the tradeoffs in the various methods for calculating net savings that will help policymakers, regulators, and program administrators decide which are best to apply.

The original version of the document was published in September 2014, but has since been updated to include modified definitions of net and gross savings, a reorganization of key concepts, and an expanded discussion on survey methods based on recent developments.
