The Bonneville Power Administration's 2017 Evaluability Assessment identifies important factors to consider for future evaluations of SEM program savings, including describing how the program will be operated and insights on the program’s evaluability. The report further describes findings from a review of the savings estimation modeling conducted for three pilot buildings and provides recommendations on how this modeling may be improved. This review of the pilot buildings also helped to identify and refine factors that should be considered in planning for future evaluation of this program.
