As the push for decarbonization accelerates, the electrification of heating and domestic hot water (DHW) systems in existing multifamily buildings presents both opportunities and unique challenges. This session will share real-world insights from our experience in designing, installing, and commissioning central heat pump systems in affordable multifamily buildings, with a focus on cold-climate performance and space-constrained environments.
We will explore key technical and logistical hurdles encountered in retrofitting existing buildings, including managing limited mechanical space, integrating with legacy infrastructure, and ensuring system efficiency during extreme weather conditions. Through case studies and real-world data, we will highlight strategies we have employed to overcome these obstacles—such as innovative system design approaches, equipment selection tailored to site-specific constraints, and optimization techniques for performance and occupant comfort.

Attendees will gain practical knowledge on how to approach multifamily heat pump retrofits effectively, understanding not only the technical aspects but also considerations related to true cost, project timelines, and long-term operational success. This session aims to equip energy professionals with actionable strategies to advance decarbonization goals in the multifamily sector.
