The Model Energy Efficiency Program Impact Evaluation Guide is provided to assist gas and electric utilities, utility regulators, and others in the implementation of the recommendations of the National Action Plan for Energy Efficiency (Action Plan) and the pursuit of its longer-term goals. 

This guide describes a structure and several model approaches for calculating energy, demand, and emissions savings resulting from facility (non-transportation) energy efficiency programs that are implemented by cities, states, utilities, companies, and similar entities. By using best practices and consistent procedures, evaluations can support the adoption, continuation, and expansion of efficiency programs.
