Johnson 001 <br />Controls <br />Domestic Water Heater Replacement: In addition to the new boiler plant, the existing domestic <br />water heaters are inefficient and getting close to the end of their useful life. Because the new boiler <br />plant will be a sealed combustion system, installing the new high efficiency water heaters will allow <br />the present exhaust fans and dampers to be eliminated. The water heaters will be correctly sized for <br />the load of the building. <br />Finned Tube Radiation (FTR) Addition: In the Family Services area, the classrooms have FTR. <br />This section is being controlled by an individual pneumatic thermostat. This thermostat is not able to <br />work with the existing VAV box. New digital controls will be installed to work with the VAV box. <br />Many of the office spaces have heating issues in the winter time. This is caused by the heat transfer <br />of the hot air through the outside wall. This wall is cold and needs to be washed with heat to <br />eliminate this issue. With several rooms being controlled by a single VAV box, rooms will either <br />overheat or under heat because the thermostat is located in the wrong space. By adding FTR to these <br />spaces, the overheating of spaces would be eliminated and the proper amount of heat for each space <br />would be provided. <br />FIM I Boiler Plant Conversions and Modifications <br />CH2 I City Hall <br />• Implement Start / Stop Schedule <br />• DDC Start / Stop of all Air Handling Units <br />• New: Actuators on dampers <br />• New: Wiring for all units. <br />• Implement demand control ventilation strategies <br />o AHU -1 <br />• RTU Replacement <br />• Remove Existing five (5) DX Roof Top Units <br />• Install Four (4) new DX Roof Top Units <br />• Implement variable - frequency drive ventilation/pumping applications <br />• AHU -1 <br />• HW distribution pumps with variable speed drives and a differential pressure <br />sensor <br />• Replace 34 existing VAV Box controls <br />o Replaces pneumatic controls with new DDC valves and thermostats. <br />• Replace 6 existing FTR Valves <br />o Replaces pneumatic valves with new DDC valves. <br />• Provide new DDC valves: <br />• AHU -1 <br />• AHU -2 <br />• Install one (I) New VAV Box <br />o Install box for new DDC valves and thermostats for police station. <br />• Install new destratification fans in selected high bay areas <br />• Five (5) in Main Gymnasium <br />• One (1) in Aux.
