Energy efficiency savings have grown substantially in the past ten years, and national leaders in program administration have emerged as savings levels have increased. This report reviews annual program performance for 14 leading energy efficiency program administrators, with a focus on costs, electricity savings, cost effectiveness, and portfolio design.

This publication summarizes program design, marketing, workforce development, and other key takeaways learned during Peer Exchange Calls.

This report was developed to help inform national stakeholders about the strategies that have been used to achieve deep energy savings in the multifamily housing sector through energy efficiency upgrades. These strategies could be used as models in areas where utility program administrators and policymakers seek to achieve deep energy savings in the multifamily building stock for the purposes of reducing energy costs, creating comfortable and healthy homes, meeting regulatory requirements, or reducing the environmental impacts of energy consumption. This report includes a national multifamily market characterization, barriers and opportunities for program and policy efforts, and eight exemplary case studies from across the country.

The report makes the case for establishment of common data collection practices for energy efficiency lending. The report reviews existing practices for the collection of four categories of data from energy efficiency financing programs: (1) customer data; (2) financial product and performance data; (3) facility-level data; and (4) energy efficiency project data. The report then identifies high-priority needs, characterizes potential uses for finance program data, and identifies use cases that describe how stakeholders use data for key objectives and actions.

This paper explores ways in which program administrators are using social norms to spur behavior change and, as a result, curb energy use. In recent years, home energy reports (HER) programs have applied the concept of social norms to the energy efficiency context. These feedback programs inform customers of how their energy consumption compares to their neighbors' and provide other information about their usage, with the goal of enticing customers to change their energy use behavior to improve their relative neighborhood ranking.
