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.

This article is an overview of HUD's Green and Resilient Retrofit Program (GRRP). It was developed with help from National Housing Trust (NHT) and Stewards of Affordable Housing for the Future (SAHF). GRRP, a $1B IRA program, has issued $1M in awards but the program has seen lower application volume than expected to date, leaving more resources still available for applicable projects. The article recommends that developers assess their portfolios for eligible HUD subsidized properties, so these resources are not left on the table. It also includes information on changes to make it easier for housing owners to incorporate funding into their projects.

Geothermal heat pumps offer highly efficient heating and cooling without fossil fuels. They are especially valuable in supplying heating on extremely cold days and support heating electrification with only modest impacts on electric grids. These heat pumps are widely applicable from single family homes to large properties, or even networked systems providing heating and cooling to entire neighborhoods. The blog article highlights the characteristics of this technology and new opportunities for greater adoption.

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.

This blog post summarizes a larger study on an equitable energy transition based on the actions of Oshkosh, Wisconsin, a small Midwestern city. The goal was to balance decarbonization and climate goals, ensure equity, and operate within budgets.

Advanced Energy Design Guide for Multifamily Buildings-Achieving Zero Energy (AEDG) is the third in the AEDG zero energy guide series. The design guide outlines strategies for achieving energy targets such as setting measurable goals, hiring design teams committed to those goals, using simulation throughout the design and construction processes and being aware of how process decisions affect energy usage. In this edition, content has been included on renovation and resiliency along with expanded guidance on hot water and high load in multifamily buildings.

This blog post details the U.S. Department of Energy's (DOE) finalization of Part 1 of a national zero emissions building definition, emphasizing operational carbon emissions. This definition outlines three key criteria for buildings: energy efficiency, no on-site emissions, and the use of all-clean power sources. It aims to enhance public health, lower energy costs, and protect the climate. The post highlights the positive industry and advocate reactions, notes the importance of addressing embodied carbon in future updates, and explains how new and retrofitted homes can meet the definition. It emphasizes the economic feasibility and investment potential in zero-emission buildings and outlines steps for builders to achieve compliance.

This post examines the work involved to incorporate decarbonization and resilience upgrades into multifamily retrofits. Industry leaders share their perspective on the considerations the affordable housing industry must keep in mind to meet this moment.
