As part of an effort to analyze the cost per unit of savings for utility customer-funded energy efficiency programs, Lawrence Berkeley National Laboratory (LBNL) has reviewed regulatory filings nationwide to produce a program typology and standardized data metrics for assessing energy efficiency program characteristics, costs and impacts. These types, definitions, and naming conventions facilitate meta-analysis of efficiency program results and use of such information by a wide range of entities.
This policy brief discusses the program categories and definitions, which are based primarily on review of several years of annual energy efficiency reports from 108 program administrators in 31 states for approximately 1,900 unique programs. The categories and definitions were also informed by publications from the State and Local Energy Efficiency Action Network (SEE Action), the Consortium for Energy Efficiency (CEE), the Northeast Energy Efficiency Partnerships’ EM&V Forum, and the American Council for an Energy-Efficient Economy (ACEEE).
The LBNL program categories capture the range of program types observed throughout the country. This level of detail provides flexibility for grouping programs by a variety of common characteristics for comparison and analysis (e.g., organizing programs by technology versus sector).
