The unique aspect of this job is the large number of interfaces that were required. There are interfaces to 14 different systems using BACnet over 44 Ethernet connections and 9 BACnet MSTP communications trunks. One of the challenges was to interface to 773 indoor LG variable refrigerant fan coil units. Another challenge was the interface to multiple electrical systems which are not typically BACnet compatible such as emergency generators, automatic transfer switches, lighting panels, and energy meters.
