Convert plant to Integrated Primary/Secondary® design •Reconfigure tertiary pumps to alleviate system pressure problems and eliminate wasted energy •Remove building pump bypass check valve •Pragmatic approach involved adding VFDs to only 3 of 6 primary chilled water pumps•Design and install PLC based adaptive control algorithms to ensure maximum chiller loading, optimal control of all CHW pumps and proper balance of cooling towers and chillers IMPLEMENTATION•CEO ® system connected directly to T.A.C. Continuum system via BACnet IP protocol, allowing tekWorx to pass data for trending and alarming purposes•Chilled water system was converted to full variable flow and adaptive control system controls all plant equipment (chillers, pumps, cooling towers, etc.)•Failover sequence developed
