The catalog is a compilation of state and local energy efficiency potential studies to serve as a resource for energy planners and as a baseline for future analyses.

This report updates ACEEE's 2013 assessment of multifamily energy efficiency programs in US metropolitan areas with the most multifamily households. Using housing, policy, and utility-sector data from 2014 and 2015, this report documents how these programs have changed in the context of dynamic housing markets and statewide policy environments. The report also offers an analysis of the number, spending, offerings, and targeted participants of current programs and their potential for further expansion.

This Guide is designed to help state and local policymakers to take full advantage of new policy developments by providing them with a comprehensive set of tools to support launching or accelerating residential energy efficiency programs. The Guide focuses on four categories of policies that have proven particularly effective in providing a framework within which residential energy efficiency programs can thrive: incentives and financing, making the value of energy efficiency visible in the real estate market, data access and standardization, and supporting utility system procurement of energy efficiency.

This report provides state and local policymakers with information on successful approaches to the design and implementation of residential efficiency programs for households ineligible for low-income programs.

This report describes how utility planning processes that allow demand-side resources to compete with supply-side resources can promote cost-effective energy efficiency.

This report considers consumers' perspectives on policy and regulatory issues associated with the administration of energy efficiency investments funded by ratepayers of electric and natural gas utilities.
