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 research described in this report holds great potential to significantly improve the process for including energy efficiency in developing and implementing federally funded multifamily rehabilitation projects through the USDA, the U.S. Housing and Urban Development (HUD) Low Income Housing Tax Credit, and other programs.

This study documents the market valuation associated with the predominant green and energy efficiency home certifications used in the Northwest. Regional markets with a track record of including green building and energy efficiency information in MLS databases have lacked a recent, thorough, locally relevant analysis of the potential value of “higher performing” homes in current market conditions. Real property appraisers require a reliable, localized, granular analysis they can use in their home valuation calculations. The analysis contained in this report addresses this identified market need.

This summary from a Better Buildings Residential Network peer exchange call focused on changing an organization's home performance business model and expanding the services offered.

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.

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.

The MPower Toolkit provides templates, resources, and lessons learned to address the barriers faced by the affordable multifamily housing sector when accessing energy efficiency upgrades. The toolkit is also intended for all stakeholders involved in efficiency programs, including efficiency program administrators, state and local leaders, utilities, energy consultants, and financial partners. MPower's core model is useful for all building types. In addition, the toolkit’s chapters are broken out into segments that highlight information and innovations that many efficiency programs are incorporating into their own models. The toolkit is a resource for all practitioners involved in implementing MPower and also serves to assist practitioners of other established efficiency programs. The MPower Toolkit draws from the experience of MPower Oregon, although it differentiates between the core MPower model and how MPower Oregon implemented this model.
