Research Themes +
Energy Technologies Area (ETA) researchers are continually building on the strong scientific foundation we have developed over the past 50 years. We address the world’s most pressing climate challenges by bringing to market energy-efficient innovations across the buildings, transportation, and industrial sectors. ETA is at the forefront of developing better batteries for electric vehicles; improving the country's aging electrical grid and innovating distributed energy and storage solutions; developing grid-interactive, efficient buildings; and providing the most comprehensive market and data analysis worldwide for renewable technologies like wind and solar.
Strategic Initiatives +
The Energy Technologies Area (ETA) Strategic Plan is the guiding force for our research and development for the next ten years. It clearly charts a path toward clean-energy solutions and focuses on five detailed Strategic Initiatives. The Plan provides an in-depth look at how ETA is accelerating research to provide affordable, clean energy to all while accomplishing deep, economy-wide decarbonization, looking to avoid a rise in global average temperature while simultaneously developing solutions to increase humanity's resilience to extreme weather volatility.

Abstract

This paper analyzes current policies and practices related to the incorporation of non-energy measures (NEMs) and their benefits to energy saving performance contract (ESPC) projects implemented by the U.S. energy service company (ESCO) industry. Previous research by our team has found that projects in the public and institutional sector are increasingly using ESPCs to address various non-energy-related needs (e.g., roof replacement). Unfortunately, there is no consistent guidance on methodologies for incorporating non-energy benefits (NEBs) into the cost/benefit analyses of projects. This paper presents the results of an in-depth review of state-by-state and federal legislation of the incorporation of non-energy benefits, including measures and benefits allowed and restrictions that apply.

Case studies indicate that the value of NEBs can be as much as 40% or more of the total economic savings generated by an ESPC project. However, there is significant variation across regions and levels of government, with regard to how many and which types of non-energy measures are allowed in ESPC project contracts. There appears to be little or no correlation between the level of government infrastructure needs, which can be extensive, and the number of non-energy measures allowed by the jurisdiction. The authors recommend standardized, simplified, and transparent methodologies for estimating and verifying the savings generated by the various non-energy measures—in a manner that is analogous to the original development of the International Performance Monitoring and Verification Protocol (IPMVP).
