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.
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.
Among the many benefits ascribed to energy efficiency is the fact that it can help create jobs. Although this is often used to motivate investments in efficiency programs, verifying job creation benefits is more complicated than it might seem at first. This paper identifies some of the issues that contribute to a lack of consistency in attempts to verify efficiency-related job creation. It then proposes an analytically rigorous and tractable framework for program evaluators to use in future assessments.
This study looks at evidence of capitalization of energy efficiency features in home prices using data from real estate multiple listing services (MLS) in three metropolitan areas: the Research Triangle region of North Carolina; Austin, Texas; and Portland, Oregon. These home listings include information on Energy Star certification and, in Portland and Austin, local green certifications. Our results suggest that Energy Star certification increases the sales prices of homes built between 1995 and 2006 but has no statistically significant effect on sales prices for newer homes.
The study was completed on behalf of the Minnesota Department of Commerce to characterize energy use in the state's multifamily sector and to identify untapped energy efficiency opportunities. Working with Franklin Energy, the field study gathered characteristic data for 120 representative buildings across the state as well as survey data of both building owners and tenants. Using this data as well as a utility billing analysis, the Energy Center of Wisconsin (now Seventhwave) developed an in-depth characterization for a hard-to-reach sector in Minnesota that had not been, up until this point, studied to this degree.
This report provides information on how supporting access to building benchmarking data can help utilities increase efficiency and drive down energy demand.
This report provides information on how energy use data access can help state governments lead by example through benchmarking and disclosing results and implement benchmarking policies for the private sector.
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 identifies and discusses factors that should be considered in evaluating model choices for administering and implementing ratepayer funded energy efficiency 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 report provides an overview of evaluation, measurement, and verification approaches used to estimate the load impacts and effectiveness of energy efficiency programs.
This report summarizes the scale and economic value of energy efficiency for reducing carbon emissions and discusses barriers to achieving the potential for cost-effective energy efficiency.
