Primary plant, including chillers, cooling towers, fresh air ventilation, boilers, and pumps, is located across basement and roof levels. Local systems are supported by supplementary plant on the office floors, where comfort conditions are maintained via a 4-pipe fan coil unit (FCU) system.
The existing Trend BMS infrastructure is a combination of legacy and partially upgraded components, including IQ3, IQL, IQ4, and IQEco controllers. A partial system upgrade was completed in 2018, which included:

- Upgrade from Trend 963 to Trend IQVision graphical user interface

- Removing obsolete I/O modules and integrating new hardware with existing field wiring
