The U.S. Department of Energy (DOE) and the DOE National Renewable Energy Laboratory (NREL) published additional protocols for estimating energy savings for residential and commercial energy efficiency programs and measures. The new protocols address the following measures: chillers, commercial new construction and retrocommissioning. In addition to these protocols, the project has published a report that focuses on the methods used to estimate net energy savings in evaluation, measurement, and verification (EM&V) studies for energy efficiency (EE) programs: estimating net savings: common practices. Over time, DOE believes this will reduce the cost of program evaluation, measurement, and verification and improve deemed savings estimates used in technical reference manuals across the country.
