Technical Reference Manual

A Technical Reference Manual (TRM) is a resource used to help plan and evaluate energy efficiency programs. TRMs outline how much energy can be expected to be saved for certain measures, either through deemed savings values or engineering algorithms. TRMs also contain source documentation, specified assumptions and other metrics associated with energy efficiency measures. Illinois, Indiana, Iowa, Kentucky, Michigan, Minnesota, Missouri, Ohio and Wisconsin use TRMs to plan for, quantify, report and document savings from (and other metrics related to) energy efficiency measures.

MEEA recently completed a “Midwest TRM Inventory” to better understand the use of TRMs or equivalent tools in the region. The Midwest TRM Inventory involves an in-depth look at statewide, administrator-specific and regional TRMs. MEEA staff analyzed which energy saving measures are included in each and identifying gaps in included measures that may provide opportunities for additional measure offerings. MEEA is also reviewing the processes involved in TRM development, uses and maintenance.
