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.

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.

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.

This case study provides an overview of the adaptive reuse of the historic Ohringer Building in Braddock, PA. Guided by the Enterprise Green Communities 2015 criteria, developers were able to transform this local landmark into affordable, climate-ready housing while preserving the history and integrity of the building.

Salem Heights Apartments, an affordable multifamily property in Massachusetts, recently underwent a deep energy retrofit to achieve passive house performance. This case study highlights the retrofit design strategies that enable 60% energy use reduction and show the integrated benefit of efficiency improvements, electrification, and solar. Specific strategies are described for the building envelope, exterior insulation, HVAC, and solar energy.

Over half of California’s 3.2 million multifamily units were constructed before energy efficiency standards, resulting in poor performance and high greenhouse gas emissions. To achieve California’s greenhouse gas reduction goals, affordable multifamily housing must improve energy efficiency, reduce carbon emissions, and lower tenant utility bills while enhancing quality of life. Yet building owners face many challenges to improving the performance of their buildings. This report covers the role certain types of energy service agreements, combined with federal incentives, can play in scaling affordable multifamily retrofits.

The Elevate Community Solar Pro Forma provides users with a simple tool to assess the financial performance of the installation and long-term subscriber management of proposed community solar projects.
