This study provides an overview of practices for quantifying and reporting avoided energy-water costs from demand-side measures. It also summarizes the regulatory guidance for incorporating water savings into cost-effectiveness screening for energy efficiency programs.

This report is a guide to all customer-facing financing products—products offered by a lender directly to a borrower—used to pay for energy efficiency. Intended for state and local governments that are deciding whether to start a new program, tune up and existing program, or create a Green Bank, it provides information on the full range of financing product options for target participants, the tradeoffs of various products, and potential advantages and disadvantages for different types of customers.

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 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 report explores the approaches and research needs identified in the Building Retrofit Industry and Market (BRIM) Initiative through in-depth discussion with residential energy upgrade experts including a discussion of Marketing & Outreach and the program/contractor interface.

This report describes different approaches to energy efficiency finance taken by utilities.

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.

This report provides comprehensive information on state, federal, local, and utility incentives and policies that are in place to support renewable energy and energy efficiency.
