-0 <br /> Clinic Build out Remodel Section 1 <br /> ECM-1 Heating and Building Controls Upgrade <br /> The Air supply from the air handling unit is distributed through secondary branch ductwork with Fan <br /> Powered Variable Air Volume(FPVAV)boxes with reheat coils. The new clinic section does not have a <br /> source of controllable heat to the new spaces.The new Clinic area does not have any building control <br /> system installed. It is our recommendation that new VAV boxes with hot water reheat coils be installed <br /> which would provide for the proper control of supply air,improve comfort for all spaces,improve <br /> dehumidification and reduce fan energy by slowing down the fans during low load conditions.It is also <br /> recommended that room thermostats be installed in order to control temperature to the spaces.The <br /> thermostats along with the VAV boxes will be integrated into the existing building automation system <br /> along with graphics to monitor and control operations.By making the upgrades to the system,you will be <br /> able to properly control space temperature,provided a consistent design as the rest of the Library building <br /> and not compromise the efficiency and performance of existing areas in the building. <br /> Recommendations <br /> 1) Install new VAV boxes with reheat coil,VAV-Re Heat(VAV-RH)boxes. <br /> 2) Reconfigure Ductwork serving VAV boxes to improve air flow and zone control <br /> 3) Install new piping and extend to new VAV boxes including new valves and DDC controls <br /> 4) Install new ductwork and transitions for the New VAV boxes and connect to the new supply duct <br /> branches. <br /> 5) Install transition ductwork from existing ductwork to the round inlet and VAV-RH outlet to the existing <br /> ductwork. <br /> 6) Make new connection to existing hot water supply&return piping and extend to new reheat coil with <br /> new balance valve,control valve,shut off valves and vents. <br /> 7) Provide lifts for installation of VAV boxes and replace all damaged ceiling tile. <br /> 8) Install new DDC controllers on each VAV box including thermostat,programming and wiring. <br /> 9) Provide air&water balancing for each new VAV-RH box. <br /> 10) Provide As built drawings for project <br /> Scope of Work <br /> 1) Provide VAV Boxes to Mechanical Contractor for installation. <br /> 2) VAV Boxes to include factory installed controls. Includes VAV-1,VAV-2,FPVAV-3,VAV-4,VAV-5 thru <br /> VAV 10 <br /> 3) Provide VAV Reheat Coil control valves to Mechanical Contractor for installation <br /> 4) Provide and install temperature Controls for ten(10)VAV boxes including new thermostats, <br /> transformers,controllers and associated low voltage wiring. Note:no thermostat for air valves,these <br /> will be set for constant volume airflow. <br /> 5) Install network bus to communicate all available points to the BAS including graphics. <br /> 6) Provide field time to assist air balancer for balancing of each VAV box. <br /> 7) Provide startup and validation of all points <br /> ®2022 Johnson Controls,Inc.—Do not copy(physically,electronically,Or in any <br /> other media)without the express written permission of Johnson Controls,Inc, <br />
