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.

Electrifying heating systems with air-to-air heat pumps is crucial for achieving global greenhouse gas targets. This report uses simulations of 550,000 U.S. households to evaluate the costs and benefits of various heat pump performance levels and insulation upgrades. The analysis highlights the potential for significant emissions reductions and identifies the importance of efficiency and insulation in optimizing cost-effectiveness. It also suggests that supportive incentives and policies may be necessary to address affordability challenges and promote widespread adoption.

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.

Communities across the nation are regularly experiencing natural disasters or recovering from them. While all communities are at risk, low-income communities are disproportionately affected by climate events and often have limited resources to recover. This guide provides owners and operators of multifamily housing with practical guidance on re-designing and retrofitting their buildings to adapt to and provide protection from climate risks and other potential hazards.

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.

This case study showcases Allston Brighton CDC’s approach to decarbonizing multiple properties through deep energy retrofits. This nonprofit affordable housing owner in Boston has emerged as a champion of building decarbonization. They are poised to cut energy consumption by an impressive average of 55% across 103 residential units. What’s more, their team members have offered a one-page guide for similar building owners and projects on how to pursue various funding sources for retrofit success.

This article outlines steps lenders can take to pursue incorporating energy lending into their activities. It recommends evaluating current  lending for existing energy-related scopes as well as ways to expand to standalone products and work with state and local partners rather than focusing on the federal level.
