CONTROL EQUIPMENT LOCATION CURRENT CONDITION DESIRED CONDITION

Exhaust Fans Parking Garage

Controls or Programming not functional.

Fans currently operate 24/7/365. Fans should be controlled by CO sensors.

Boilers Mechanical Room

Originally the 4 Boilers were controlled by a Weil‐Mclean Boiler control and the building automation system only sent an on/off command. The Weil‐Mclean control was scrapped and a basic Johnson

Control system was put in its place. It is not in an electrical box, but sitting on top of abandoned Weil‐Mclean box. Wiring is not code compliant. Outside air temp sensor was ran with non‐plenum thermostat wire and is going up through the existing mechanical room exhaust fan hood and the wire comes out of a vent on the side of the exhaust fan into a LB fitting with the sensor inside. Also, we currently do not have any status and temp sensors going to BAS to notify us when a boiler goes down. It has to be manually assessed in person.

Replace the current controls for all 4 boilers to full automation, with graphics, override controls, etc. All work shall be done in conformance with applicable codes.

Fin Tube Coils Throughout Building

Currently all fin tube radiant heaters are controlled through the nearest VAV box controller. Every fin tube heater in the building does not function automatically with a change in room temperature. It has become standard operation to manually override all fin tube valves through the corresponding VAV in order to turn them off and on. Some VAV box controllers are not operational at all, and staff must manually turn on/off valves to these tubes each spring and fall.

Repair, replace or add VAV box controllers that are not functional. Update programming for VAV and fin tube control based on temperature and schedule.

Rooftop Chiller Roof

There are currently no alarm interlocks into the BAS indicating when the Chiller has gone into alarm. It requires someone to go onto the roof and access the control panel on the Chiller to find out if the system has any faults, alarms or lockouts present.

The new automation system needs to be tied into the chiller control system so the building operator can view chiller alarm status without going to roof on a daily/weekly basis. An indicator of alarm on the BAS system will help in more timely response to a failed component in the system before the entire chiller is down.

VAV's Throughout Building

The individual operation and controls of the VAV boxes are not functioning when changes are made. It's as if the points and programing links in the background were not set up properly so making changes does nothing on several points on many if not all VAV controller user interface BAS pages. It is difficult to control the airflow in heating and cooling seasons with limited functional control of listed features on respective VAV control pages. Also, zone setpoint is out of service on VR‐6 and VR‐

19.

Repair, replace or add VAV box controllers and update programming to address this issue.

VAV's 2nd Floor

VAV boxes are uninsulated and when building humidity is high, condensation would form on the sheet metal causing rusting along with condensation dripping onto the ceiling tile. Many ceiling tile were replaced over the years because of this problem.

Situation has been improved, if not completely corrected, with changes made to the dehumidification programming of the building. Issue should be investigated after all BAS improvements are complete and VAV boxes should be insulated as needed under the alternate bid item.

BAS Graphics Throughout Building Non graphics based system.

The new system shall be graphics based to assist in the visual understanding of the operation of the entire system by the building operator. Status of operation of components, inlet and outlet temps of piping and air flow devices, etc. broke down by component and floor level for quick reference in the automation system.

OA/Humidity Sensor Mechanical Room & Building Exterior

Original OA/Humidity sensor for the system was previously located in the OA inlet air duct on the South side of the building. This never allowed the system to accurately function as the sun had a significant effect on the sensor causing it to read high during the daytime, and the humidity sensor did not get consistent outside airflow causing it to give unreliable results. Johnson Controls installed a new

OA/Humidity Sensor on the Northeast corner of the building and abandoned the original in duct sensor. We were able to increase energy savings utilizing greater

OA cooling vs. mechanical along with limiting OA air into the building when outside humidity high limiting the need for excessive dehumidification operation. At this time our dehumidification programming was adjusted and has been functioning better than ever.

Maintain current configuration, but replace sensors as needed.

EQUIPMENT LOCATION ISSUE / PROBLEM ADD TO BAS

Future Controls Dispatch Add conduit, wiring and box to control future AC system No

Future Controls Radio Room Add conduit, wiring and box to control future AC system No

Temp Sensor Radio Room

There is a stand‐alone ductless split air conditioning system that is used to cool the radio control room. This system is not a part of the

BAS. At minimum, a temperature sensor shall be installed and monitored on the new BAS and an alarm alert be sent when the room temperature gets above desired temp, indicating the cooling system is not working. This would allow quicker notification/response time for repairs or other arrangements to keep the equipment cool so that it does not overheat and go offline or worse. Yes

Future Controls

LL‐2 elevator rooms, generator room, water service room, all emergency stairwells and lobby entrances with unit heaters

We have had several instances where the heater would stop working and the pipes would freeze and burst in these areas. It would be beneficial, at minimum, to have a temperature sensor in these rooms in order to monitor temperature. An alarm in the BAS when the room temp falls outside of an acceptable range would be an early alert for potential freeze issues. Secondly, a full automation with status of these components could be but on the automation for remote testing of operational function to ensure proper operation in a more proactive manner. Yes
