Thermostatic radiator valve (TRV) Demonstration Project

This research measured the energy savings associated with installing thermostatic radiator valves (TRVs) on one-pipe low-pressure steam systems in New York City multifamily buildings. There were three primary objectives: to determine whether fuel consumption was lower in buildings using TRVs: to determine if occupants would accept the TRVs: and to determine if overheating in apartments could be eliminated using TRVs.
