Modular Multifamily Passive House: Design, Build, and Verify

LaMora Senior Living in Westchester, NY is the first completely modular Phius certified multifamily building in the world. This session presents the challenges faced relative to enclosure design, construction, and verification of this project, which does not follow the traditional site-built process. It includes specifics about the approach of designing a large multifamily building (trash, ventilation, out-of-boundary programs) as well as the difficulties of verifying a project in factory and field.
