Stewards of Affordable Housing for the Future's (SAHF)'s case study explores learnings from Preservation of Affordable Housing's (POAH's) Salem Heights development, which electrified the HVAC system and improved the building envelope. The report shares details about the funding used and other strategies employed to make the project come together.

Stewards of Affordable Housing for the Future's (SAHF)'s case study explores challenges and achievements from The Community Builders' North Commons at Village Hill development in western Massachusetts, built to the Passive House standard. The case study shares the developer's perspective on assembling a team, electrifying hot water heating, and installing Phius-compliant windows. Ultimately, the benefits outweighed the costs for this development.

This report examines how budget-constrained households balance spending on air conditioning versus other essentials like food and clothing during hot weather. Using banking data from Houston, Los Angeles, and Chicago, it finds that low-income households often cope with high electricity bills by reducing air conditioning use and enduring more heat. The findings aim to help policymakers identify strategies to better support these households and improve their welfare amid rising temperatures.

Compiling national outdoor air pollution data from across the government and other expert sources, this report shows the extent of the harm caused to people and the environment from fossil fuel burning equipment in homes and buildings, the disproportionate impact this pollution has on environmental justice communities and other vulnerable demographic groups, and how the use of methane gas in buildings is connected to the broader system of methane gas extraction and distribution.

To better understand the barriers limiting the decarbonization of affordable housing beyond what energy and cost analyses could provide, NRDC commissioned an Arup-authored study of energy retrofits of affordable multi-family housing buildings within the Los Angeles metropolitan area. The study examined five real-world examples to expose obstacles, inefficiencies, and opportunities encountered during retrofit processes. Six key challenge areas emerged that must be addressed to enable decarbonization of affordable housing at scale: carbon reduction strategies, financing, implementation, policy, technical expertise, and tenant impact.

This report looks at the existing research on climate and housing in the U.S, in two key areas: how housing decarbonization and production strategies can reduce pollution to mitigate climate change, and how climate change impacts renters, homeowners, and the broader housing industry. The paper also identifies key research gaps where more evidence would help policymakers to navigate the tensions between different policy approaches.

WE ACT's Out of Gas, In with Justice pilot studied the feasibility and benefits of electrification in New York City Housing Authority (NYCHA) by comparing improvements to air quality and participant satisfaction between 10 apartments with induction stoves and 10 with their existing gas stoves. It is the first study of its kind to focus on the effects of residential cooking electrification with tenants in-place in an urban public housing setting with low-income residents and residents of color. This pilot offers lessons for policymakers, public housing agencies, and affordable housing providers on cooking electrification and its impact on indoor air quality, social acceptance of electrification measures, and infrastructure challenges for existing housing in environmental justice communities.

The IRA presents an immense opportunity, but delivering those resources where they are most needed is no easy task given systemic barriers that often prevent low-income and communities of color from applying for and adopting green energy opportunities. In this blog post, Decarbonization Fellow Kiera Quigley explores why new funds and programs "must center the needs and voices of environmental justice communities, or threaten to leave them behind."

Multifamily housing accounts for 20% of greenhouse gases. That makes taking advantage of unprecedented incentives and funding via the Inflation Reduction Act critical. This blog post previews new tools from Stewards of Affordable Housing for the Future (SAHF) and Cadence OneFive to help the affordable housing sector unlock the potential of this landmark investment in affordable housing and energy efficiency.

Green building certifications provide benefits for a wide range of building stakeholders, with a focus on residents. The systems establish a roadmap that development teams can use to design and construct healthy, highly efficient buildings. This review provides a comparison of multifamily green building certifications to help stakeholders understand the relevant requirements and value proposition of each rating system. Analysis focuses on the application of these certifications to multifamily affordable developments in Colorado, including Housing Tax Credit developments.
