A persistent housing shortage in California and beyond is driving demand for affordable, sustainable housing which also serves overarching concerns of equity and social justice. Many building industry professionals are responding to this mandate, and are working to build a new generation of multi-family housing that is both affordable and sustainable — with many reaching LEED Platinum and/or net zero energy targets. Although cost constraints in the affordable housing sector pose their own unique challenges, several conditions align that help overcome these barriers. For example, non-profit developers are frequently owner-operators, and are incentivized to reduce long-term energy and operational costs. They are also less likely to simply pass on such costs to tenants, in comparison to for-profit developers, thereby mitigating the principal-agent problem that impacts much multi-family development.
This session featured seasoned professionals — from architecture, engineering and non-profit development — who presented case studies and discuss proven and effective strategies, as well as lessons learned from recent practice, as they work towards creating affordable and sustainable housing.
This public event was co-organized by the PG&E Pacific Energy Center and the Center for the Built Environment (CBE) at UC Berkeley.

This session qualifies for 2 AIA CES learning units with HSW. At the conclusion of this course, participants will be able to:
- Explain building systems and technologies that are effective for electrification, energy efficiency and water savings in multi-family housing.
- Cite multiple case study examples, completed or in development, of low- and zero-energy affordable multi-family housing developments, and understand how barriers were overcome in these cases.
- Understand how reducing energy and operational costs offers benefits for both tenants and non-profit housing owner/operators, and adds financial value to developments’ bottom lines.
- List common characteristics of affordable housing development that enable high energy efficiency, such as low window-to-wall ratios, and long-term ownership by owner/developers.
- Summarize finance and policy concepts that can be leveraged to overcome cost constraints to include energy efficiency measures in affordable multi-family housing.
