The following HVAC Outage has been Confirmed:

Outage:      Testing and Balancing of ARC Building AHU-1, AHU-5, Chiller, and Boiler System
Proposed By: Carroll W. Jones
Start Time:  10/07/2016 08:00
End Time:    10/07/2016 17:00

Description/Impacts:
Testing and balancing (TAB) activities will be conducted Friday.

AHU-5 balancing will only impact the non-lab areas located within the three story lab area.

AHU-1 balancing activities will require all labs to be switched to occupied (of standard) mode of operation which is maximum air flow.  Impact to lab area operations should be minimal.

Balancing activities of the new cooling system chillers require AHU-1 and AHU-2 to be forced into full cooling during measurements.  Lab area discharge air from AHU-1 will be colder than normal during measurements, but the lab reheat system should compensate for the cooler main supply air.

The laboratory chiller system used for equipment cooling will not be impacted.  The laboratory chiller is not part of the work scope.

Boiler system balancing requires that all heating valves throughout the ARC Buildings (labs, conferences rooms, offices, etc.) be commanded fully open during measurements.  The impact will be areas will become warm during testing.  Depending upon the time required to perform the measurements and exactly when this task will occur, will determine if this task will be scheduled to occur sometime before or after normal business hours.
