When looking to extend its success with its legacy control system, 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. The new BMS offers a platform for monitoring plant operation and building temperatures, evaluating energy and carbon reduction initiatives, electronically initiating work orders, and informing continuous commissioning. Including these advances has required NYCHA to work across its enterprise, from Operations/Maintenance to Capital Projects, to IT, and with its business partners and consultants, to bring all the pieces together.
