When looking to extend its success with its legacy control system, the New York City Housing Authority started with open BACnet communication as the center of its new BMS architecture, leveraging its fiber connectivity between campus buildings and including advanced graphics, alarms, exception reporting, and data analytics. Including these features has required NYCHA to work across its enterprise, from Operations/Maintenance to Capital Projects and IT, as well as with its business partners and consultants, to bring all the pieces together. This session will discuss strategies used and challenges faced in the project, as well as the impact on various stakeholders.
