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 work presented in this webinar is a collaborative endeavor by the ARIES Building America team and two major affordable housing providers: Habitat for Humanity International and the factory building industry. The effort is exploring options for making major reductions in space conditioning energy use (≥ 50%) while holding the line on home affordability. Specifically, the project will develop a high-performance integrated design--effectively combining an ultra-efficient thermal envelope, a very low capacity, highly efficient mechanical system, an innovative distribution system, and affordable heat recovery ventilation--and set in motion steps to rapidly move this innovation to market.

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.

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.

Through field-testing and analysis, this project evaluated whole-building approaches and estimated the relative contributions of select technologies toward reducing energy use related to space conditioning in new manufactured homes. Three lab houses of varying designs were built and tested side-by-side under controlled conditions in Russellville, Alabama. The tests provided a valuable indicator of how changes in the construction of manufactured homes can contribute to significant reductions in energy use.

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.

This summary from a Better Buildings Residential Network peer exchange call focused on evaluation, measurement, and verification of predicted/modeled savings from home energy upgrades.

This case study presents information about the AlabamaWISE program. It includes background information, approaches the program took to enhance home energy efficiency, and results achieved by the program.

This summary from a Better Buildings Residential Network peer exchange call focused on strategies in building interest in and introducing energy efficiency to affordable housing.

This summary from a Better Buildings Residential Network peer exchange call focused on gathering and communicating loan performance data.

This report summarizes ongoing and recent policy developments that support utility investments in energy efficiency, including program cost recovery, fixed cost recovery, and performance incentives for electric utilities on a state-by-state basis.

This report provides information on how access to energy use data can help local governments create policies for benchmarking and disclosing building energy performance for public and private sector buildings.

This peer exchange call summary focused on how programs are devising plans for creating a contractor revenue stream and potential fee structures.

Highlights the EcoHouse Project Loan Program, which provides fixed interest rate loans as a tool for enabling energy improvements among households that are otherwise unlikely to be able to access affordable financing at market rates.

This peer exchange call summary focused on what energy efficiency programs are doing to target low- and moderate-income households.

This report identifies and discusses factors that should be considered in evaluating model choices for administering and implementing ratepayer funded energy efficiency programs.

This market assessment for the Alabama Energy Revolving Loan Fund identifies the customers and potential demand for an energy efficiency upgrade financing program.

This brief focuses on loan programs in 30 states that are currently providing low- to no-interest loans to finance energy efficiency improvements--from energy-efficient windows to replacement HVAC systems--in the residential, business, and public sectors.

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.
