Making the Case for Energy Efficiency Retrofits in Multifamily Buildings

Serving Hard-to-Reach customers is both inherently difficult and vitally necessary as the climate crisis continues to disproportionally affect the most vulnerable populations. Energy efficiency upgrades are the most cost-effective way to reduce energy waste and GHGs in the built environment, while lowering energy bills and improving comfort and indoor air quality. This panel will explore the challenges of implementing deep energy efficiency retrofits in multifamily projects, specifically low-income or affordable housing, and the opportunities to provide EE benefits at scale in the sector. The discussion will touch on project scope, timeline, obstacles, layering of incentive programs, expected benefits, and lessons learned. Attendees will leave with an understanding of decisions and pain points that need to be addressed for multifamily property owners to implement EE upgrades, how to support them in overcoming those obstacles, and some of the ways to leverage incentives and grants to make a project financially feasible.
