Information and communications technologies (ICT) can automate and transform the evaluation, measurement, and verification (EM&V) of energy efficiency programs. ICT enables the remote monitoring and sophisticated analysis of energy usage, increasing the speed and scale of many EM&V activities. This report reviews traditional EM&V practices, explores new enabling technologies including the Internet of Things and remote building analysis, and describes the application of ICT to each stage of the EM&V process. The report then projects ways forward through a number of challenges (e.g., data overload) and concludes that ICT-enabled EM&V could eventually change the design of efficiency programs and the responsibilities of program administrators, implementers, and evaluators.

The benefits of energy efficiency extend beyond energy savings. Homes, commercial buildings, and industrial facilities gain comfort, health, and safety benefits from energy efficiency programs. Additional benefits for businesses include savings on maintenance, materials, and the costs of regulatory compliance. On the supply side, electric utilities enjoy reduced system costs. Focusing on the residential, business, and utility sectors, this report examines each of these multiple benefits, their role in program marketing, and current best practices for including them in cost-effectiveness testing.
A number of states are beginning to recognize Demand Reduction Induced Price Effects (DRIPE) as a real, quantifiable benefit of energy efficiency and demand response programs. DRIPE is a measurement of the value of demand reductions in terms of the decrease in wholesale energy prices, resulting in lower total expenditures on electricity or natural gas across a given grid. This paper reviews the existing knowledge and experience from select U.S. states regarding DRIPE (including New York and Ohio), and the potential for expanded application of the concept of DRIPE by regulators.

Among the many benefits ascribed to energy efficiency is the fact that it can help create jobs. Although this is often used to motivate investments in efficiency programs, verifying job creation benefits is more complicated than it might seem at first. This paper identifies some of the issues that contribute to a lack of consistency in attempts to verify efficiency-related job creation. It then proposes an analytically rigorous and tractable framework for program evaluators to use in future assessments.
