Utilities and power providers in the Northwest have recently started implementing holistic energy efficiency programs with industrial facility operators to reduce energy consumption. A typical program will include several industrial facilities that vary widely in terms of production and output. Programs consist of a combination of measures, such as equipment upgrades or staff behavioral changes, that differ from site to site. To meet rebate or incentive requirements, the participant must provide energy savings estimates attributable to the program. As evaluators, we estimate program savings in industrial facilities using whole building regression analyses. This technique relies on modeling energy usage during a baseline period, then measuring savings after program implementation. Models require a variety of site specific input including production variables, weather, and changes to production, staff, or equipment. A number of approaches to modeling are commonly used. In this paper we provide a comparison of savings estimation methods defined by the Department of Energy's Superior Energy Performance and Uniform Methods Protocol guidelines and discuss the nuances of each approach.
