This report evaluates outsourcing as a tool for achieving the energy efficiency program goals. 

While offered to industrial and other large facilities primarily to ensure the reliability of energy performance, energy service outsourcing can also enhance energy efficiency in these...

Research Report - March 11, 2014

This report explores energy efficiency programs that target deep energy savings through substantial improvements to existing residential buildings. As states and regions set targets for reducing building-sector energy consumption, it is increasingly critical to scale up deep energy retrofit work...

The energy efficiency community has worked hard to engage lenders and consumers in what is estimated by the Rockefeller Foundation and Deutsche Bank to be a $279 billion market for energy efficiency investment. Great advances have been made in the federal and public sector’s program development...

Research Report - January 15, 2014

Determining the net savings impacts of a program is one of the most prominent and longstanding challenges in the utility energy efficiency field. ACEEE conducted a national review of state approaches to the net savings issue in order to help policymakers, regulators, utilities, and other...

Research Report - January 06, 2014

This report surveys energy consumption and barriers to energy efficiency for small and medium-sized manufacturers (SMM), and then describes several leading energy efficiency programs that address those barriers. SMM make up about 90% of manufacturing establishments but account for only about 50...

Research Report - December 19, 2013

As the first comparative analysis of utility-run behavior programs, this report lays the groundwork for further program development by developing a classification scheme, or taxonomy, that sorts programs into discrete categories. This study counted 281 such programs, many with multiple...

Research Report - December 10, 2013

Under traditional utility regulation and rate structures, utilities face financial disincentives for investing in customer energy efficiency programs. Unless these disincentives are addressed, utility investments in customer energy efficiency programs work against their shareholders’ interests....

Research Report - December 02, 2013

In the hunt for energy savings, multifamily buildings are widely seen by energy efficiency program administrators as hard to reach. Due to a number of challenges for multifamily building owners in undertaking energy efficiency in their properties, and for program administrators in designing and...
