The air handling units will be provided with DDC controls, supply temperature sensors, and outside air flow monitoring stations. Terminal units will be provided with supply temperature sensors.
BUILDING 310
The areas to be renovated are currently heated, cooled, and ventilated by a 40-ton constant volume rooftop air handling unit. The rooftop unit is served by an air-cooled chiller and gas-fired boiler.
The existing rooftop unit will be converted to a VAV system with fan-powered terminal boxes with hot water reheat. The existing ductwork will be completely removed and shall be replaced with a VAV duct layout matching the new space configuration. The new duct system will include medium pressure ductwork from the rooftop unit to fan-powered VAV boxes and low pressure ductwork from the boxes to diffusers. A VFD will be provided to control the supply fan speed based on maintaining downstream static pressure.
Based on the RFP zoning requirements there will be approximately (2) zones for Phase 1 and (10) zones for Phase 2. Each VAV zone will be provided with a series fan-powered terminal unit with hot water reheat coils. All return air systems will be ducted to filter grilles.
The sprinkler room will be provided with a wall-mounted electric unit heater for freeze protection and a ventilation cooling system.
The building will be provided with a partial BACNET DDC system in accordance with UFGS 23 09 23.13 20, BACnet Direct Digital Control Systems for HVAC. The partial DDC system will control all new and modified HVAC equipment and will be integrated into the existing Johnson Metasys operator workstation serving the adjacent spaces.
