The Village Hall building in the Village of Rockville Centre called for the replacement of all existing perimeter fan coil units serving the heating and cooling needs of the existing building.
The proposed design consists of a new heat pump variable refrigerant (VRF) system with energy recovery ventilation. The new VRF system design uses ducted fan coil units throughout the building. Space was a challenge for this project as the original wood frame structure was not designed to accomodate any mechanical systems. The smaller size of the ducted fan coils allowed more flexibility in designing the new HVAC system to fit within the available spaces of the buiding.
The new system was designed to maximize energy savings while improving occupant comfort and indoor air quality. Specifically, the new system will introduce mechanical ventilation to all occupied spaces, greatly improving the indoor air quality of the building. The new system is designed to replace an existing two-pipe changeover system that offered little flexibility to building occupants to switch between heating and cooling, which was done seasonally. The new system will be able to respond to changes in heating/cooling demand quickly and throughout the day. New air handlers that were designed for the project will use VRF technology along with single zone VAV control strategies to maximize efficiency and occupant comfort.
Construction of the project is expected to be completed by the end of 2018.
