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.

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.

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.

Energy efficiency collaboratives vary greatly and are typically designed for a specific jurisdiction, making them hard to compare side by side. This guide seeks to highlight a few common elements and draw conclusions on the overall effectiveness of specific characteristics of collaboratives. This guide defines and examines four different types of collaboratives in terms of their origin, scope, decision-making method, membership, duration, available resources, and how they interact with and influence their respective commissions.
