Scope of work:
This project is the largest Trane® Air-Fi® wireless system in Houston, Texas.

We took the existing BAS system that was Trane unitary controllers that were connected via BACnet comm wire to JACEs throughout the building and convert it to Trane® Air-Fi®. We converted the following equipment from the BACnet comm to Trane® Air-Fi®:
490 existing Fan Powered Terminal Units (Trane® Air-Fi®)
      - Replaced wired thermostat with Trane® Air-Fi® wireless thermostats. 
54 Existing Variable Air Volume Boxes  (Trane® Air-Fi®)
      - Replaced wired thermostat with Trane® Air-Fi® wireless thermostats. 
We kept the following equipment connected via BACnet
      - 18 Air Handling Units
      - 18 Air Handling Unit Variable Frequency Drives
      - Chiller Plant
      - Condensing Water System
40 Power meters were being monitored via integration into JACEs. 

We added the following equipment throughout the building:
85 New Fan Powered Terminal Units. (Trane® Air-Fi®)
      - Utilizing Trane® Air-Fi® wireless thermostats
68 New Variable Air Volume Boxes (Trane® Air-Fi®)
      - Utilizing Trane® Air-Fi® wireless thermostats
Integration into 20 New Leibert Units for cooling of IDF and MDF rooms
      - We added these units via integration to the Building Automation System via BACnet comm to the Trane SC+ Supervisory Device.
      - We added BTU meters at each Leibert unit and provide the data to the Building Automation System via BACnet comm wire.
Integration to 2 new Power meters.
