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.

This guide is designed to serve as a "how-to" reference for island communities (or small, similarly sized, more isolated communities) that want to develop and implement a residential energy-efficiency and conservation program. The purpose of this guide is to help communities chart a course for successful program development based on the lessons learned during implementation and operation of RePower Bainbridge, an energy-efficiency program on Bainbridge Island, Washington.

This paper first details industry best practices for contest administration, including tips for developing an overall contest plan and timeline, product sponsor recruitment, building a dynamic informational website, maximizing customer participation, selecting the winning home, seamless installation management, capturing and documenting project results, conducting a high profile media open house and facilitating customer workshops that educate homeowners and strengthen trade ally relationships. This paper then presents results and key lessons learned from more than 20 contests supported with funds from local community sustainability programs, utility energy efficiency programs, and U.S. Recovery and Reinvestment Act funds between 2008 and 2012.

This paper describes a wide variety of behavior change insights potentially applicable to the energy efficiency program context, provides examples of efficiency programs that have applied these insights, and explores some untapped opportunities to achieve energy savings through behavior change.

This guide provides background on the home improvement market in the U.S. and Canada and end users and systems in existing homes, as well as a description of energy efficiency program approaches and strategies.
