Monitored VRF Performance in New Multifamily Buildings

Speakers will review findings from a DOE-sponsored study of VRF performance in three new, multifamily buildings in New York City. Two of the buildings are affordable Passive House properties. The study focused on humidity control in apartments, finding that during the summer of 2023, average RH was often 65-70%. The study identified some clear Dos and Don'ts, but it also highlighted additional questions about this technology.
