This report explores how governments and energy efficiency implementers could help stakeholders better analyze and act upon building performance data to unlock savings.

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 multifamily sector can be hard to reach when it comes to energy efficiency programs. Besides being diverse and complex, the sector presents a unique set of challenges to efficiency investments. The result is that multifamily customers are often underserved by energy efficiency programs. Drawing on data requests and interviews with program administrators, this report summarizes the challenges to program participation and identifies best practices that programs can use to reach and retain large numbers of multifamily participants.

This paper describes existing barriers to integrating energy efficiency data into real estate markets, and illustrates recent efforts to address them. National cross-industry collaborations have resulted in standard data collection and transfer tools that allow home performance data to be shared across industries. Real estate markets in some regions have begun including these data into multiple listing services (MLS), making them visible during real estate transactions.

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.
