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.

The NorthernSTAR and U.S. Department of Energy Building America Program partnership investigated a new model to deploy building science-guided performance solutions to homeowners. This research explored three aspects to market delivery:
1. Understand the homeowner's motivations regarding investing in building science-based performance upgrades.
2. Determine a rapidly scalable approach to engage large numbers of homeowners directly through existing customer networks.
3. Access a business model that will manage all aspects of the contractor-homeowner performance professional interface to ensure good upgrade decisions throughout time.

Utilities and regulators increasingly rely on behavior change programs as essential parts of their demand side management (DSM) portfolios. This report evaluates the effectiveness of currently available programs, focusing on programs that have been assessed for energy savings. This report focuses on behavior change programs that primarily rely on social-science-based strategies instead of traditional approaches such as incentives, rebates, pricing, or legal and policy strategies. The objective is to help program administrators choose effective behavior change programs for their specific purposes.

This report details opportunities for scaling up program activity and increasing savings from programs reaching the people who need it most. It discussed best practices from existing programs for overcoming many of the key challenges that program administrators face, including how to address housing deficiencies that prevent energy efficiency upgrades, how to address cost effectiveness challenges, and how to serve hard-to-reach households.

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 report, based on U.S. Bureau of Labor Statistics data and a survey of tens of thousands of businesses across the country, provides detailed breakdowns of clean energy jobs not available previously, and it was developed and released in connection with a major U.S. Department of Energy study of all energy jobs in America.

This report discusses indoor air quality issues, including: wildfire smoke, dampness, and mold, and the effect of energy efficiency upgrades on these health-related issues. The report describes current state policies and programs in these areas, highlighting approaches for consideration by other jurisdictions.

Energy burden is the percentage of household income spent on home energy bills. In this report, ACEEE, along with the Energy Efficiency for All coalition, measures the energy burden of households in 48 of the largest American cities. The report finds that low-income, African-American, Latino, low-income multifamily, and renter households all spend a greater proportion of their income on utilities than the average family. The report also identifies energy efficiency as an underutilized strategy that can help reduce high energy burdens by as much as 30%. Given this potential, the report goes on to describe policies and programs to ramp up energy efficiency investments in low-income and underserved communities.

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.

Energy efficiency is good for you--and for the air you breathe, the water you drink, and the community in which you live. This fact sheet shows how saving energy reduces air and water pollution and conserves natural resources, which in turn creates a healthier living environment for people everywhere. It includes the stories of a family in Pennsylvania and a hospital in Florida.

The Guide to Action provides in-depth information about over a dozen policies and programs that states are using to meet their energy, environmental, and economic objectives with energy efficiency, renewable energy, and combined heat and power. Each policy description is based on states’ experiences in designing and implementing policies, as documented in existing literature and shared through peer-exchange opportunities provided to states by EPA’s State Climate and Energy Program.

A number of states are beginning to recognize Demand Reduction Induced Price Effects (DRIPE) as a real, quantifiable benefit of energy efficiency and demand response programs. DRIPE is a measurement of the value of demand reductions in terms of the decrease in wholesale energy prices, resulting in lower total expenditures on electricity or natural gas across a given grid. This paper reviews the existing knowledge and experience from select U.S. states regarding DRIPE (including New York and Ohio), and the potential for expanded application of the concept of DRIPE by regulators.

This report explores the best practices that utilities should undertake in the development and implementation of energy efficiency programs. The report calculates the impact that investing in energy efficiency will have on jobs, household income, and state and regional economies, along with the other public health benefits such as reducing pollution.

This article promotes the Greater Cincinnati Energy Alliance’s 2012 U.S. Green Building Council /Business Courier Green Business Award for Education/Outreach - Nonprofit. The award celebrated the program’s outreach approach of reaching out to homeowners directly through community engagement and neighborhood canvassing.

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

This report identifies issues associated with developing a national evaluation, measurement, and verification (EM&V) standard for end-use, non-transportation, energy efficiency activities.

This report helps policymakers understand how electric and natural gas utilities can achieve greater efficiency by establishing numeric energy savings targets and goals for energy efficiency programs.

This report analyzes the energy efficiency opportunity presented to the greater Cincinnati region. Analysis of the region and the Greater Cincinnati Energy Alliance (GCEA) programs shows potential energy cost savings, including positive cash flow from energy cost savings that consistently exceed loan payments, for both residential and nonprofit participants. Investment in energy efficiency could make counties more competitive, create jobs, reduce pollution, and help homeowners and nonprofits make cross-cutting building improvements.

This report summarizes existing research and discusses current practices, opportunities, and barriers to coordinating energy efficiency and demand response programs.

This report presents best practices for operating successful portfolio-level efficiency programs, including assessing efficiency potential, cost-effectiveness screening, and developing a portfolio of approaches.

This guide helps states and localities develop voluntary or mandatory programs that go well beyond minimum code requirements for new buildings. It addresses energy efficiency materials and resource conservation, water efficiency, indoor environmental quality, and site development and land use.

The purpose of this study is to furnish comprehensive information on ratepayer-funded low-income energy programs. This study includes information on and analysis of the energy needs of low-income households, the legal and regulatory framework supporting ratepayer-funded programs, program design options, and the findings from evaluations of program effectiveness.

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.
