Doyon Technical Services was awarded a $2.9M contract to demolish the existing HVAC system and replace it with a new variable refrigerant flow (VRF) system serving the basement, two floors of offices and work areas, and the unoccupied attic of the Upton Hall Building, part of the US Army War College. The completed HVAC system will include four separate VRF systems, one for each floor, to maximize energy recovery between spaces with differing solar exposures. Indoor ducted units and cassette units will be served by grade mounted condensing units. Two dedicated outdoor air systems will be installed on grade and will provide the building with room neutral ventilation air. Additionally, a new web based BACnet direct digital control system will be provided for all new mechanical equipment, sensors, and actuators.
