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.
New advanced Information and Communications Technologies (ICT) are pouring into the marketplace and are stimulating new thinking and a shift in the energy efficiency EM&V paradigm.

This article discusses the importance and value of evaluating energy efficiency financing programs.
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.
This paper describes existing barriers to integrating energy efficiency data into real estate markets, and illustrates recent efforts to address them.

This study examines actual loan performance data obtained from CoreLogic, the lending industry’s leading source of such data. To assess whether residential energy efficiency is associated with lower default and prepayment risks, a national sample of about 71,000 ENERGY STAR and non-ENERGY STAR-rated single-family home mortgages was carefully constructed, accounting for loan, household, and neighborhood characteristics. The study finds that default risks are on average 32 percent lower in energy-efficient homes, controlling for other loan determinants.
This study looks at evidence of capitalization of energy efficiency features in home prices using data from real estate multiple listing services (MLS) in three metropolitan areas: the Research Triangle region of North Carolina; Austin, Texas; and Portland, Oregon. These home listings include information on Energy Star certification and, in Portland and Austin, local green certifications. Our results suggest that Energy Star certification increases the sales prices of homes built between 1995 and 2006 but has no statistically significant effect on sales prices for newer homes.

Energy efficiency program evaluation is increasingly important as utilities implement programs to meet regulatory requirements, such as energy efficiency portfolio standards. While utilities need internal staff to oversee evaluation activities, most evaluations are actually conducted by outside consultants. Thus, utility staff require a sufficient understanding of the evaluation process to plan program evaluation activities as well as to manage internal stakeholders and evaluation contractors. This guide is intended to help prepare utility staff to accomplish these tasks.
