This report produced by ACEEE in 2019 investigates two emerging focuses of energy efficiency programs: SEM and EMISs. It is intended to help program stakeholders—utilities, third-party administrators, evaluators, and policymakers—understand SEM and EMIS and the programs that leverage them to save energy. The report explores the prevalence, features, and reported savings of SEM and EMIS programs along with the challenges they face, with a view to encouraging stakeholders to facilitate their offering, refine their components, and increase their prevalence.
