Technical Reference Manuals (TRMs) for Energy Efficiency Evaluation Measurement and Verification

Publication Type


Date Published




Technical Reference Manuals (TRMs) are valuable resources for state regulators, utilities, and program administrators and implementers for estimating the energy and demand savings of end-use energy efficiency measures. TRMs may also include information on non-energy impacts and factors that are used to calculate measure cost-effectiveness. TRMs are used extensively in the planning, implementation, and evaluation of utility customer-funded efficiency programs. High-quality TRMs with consistent savings values and methods can increase confidence in the quantification of impacts associated with efficiency measures and support increased implementation of cost-effective efficiency actions.

This webinar will present a new State and Local Energy Efficiency (SEE) Action Network guide on TRMs, as well as TRM experiences and approaches from experts working in three diverse states. Speakers also will give their perspectives on the guide’s recommendations.

The new guide supports the development, maintenance, and use of accurate and reliable TRMs. It includes descriptions of existing TRMs in the United States and provides recommendations for best practices based on Berkeley Lab’s review of TRMs and input from TRM developers and users throughout the country. The information and recommendations in this guide can be used to help improve the quality of existing TRMs as they are updated, and new TRMs as they are developed. The guide is posted at
