• Cutover existing system
• Upgrade controllers
• Re-engineer DDC for completed BACnet system
• Implement supply air monitoring and fault diagnosis
• Increased system monitoring
• Decreased main plant energy use
A longtime customer with an Alerton Ibex system, Ibis Hotels needed to move into the next generation of Building Management Systems to improve efficiency and improve system monitoring.
Originally a non-proprietary DDC system (Ibex). Replacement controllers no longer available, office use FCU controllers were being shifted to room use FCU controllers to enable rooms to still be let.
•Upgraded 1st level (level 10) with BACnet and MS-4 room controllers.
•Upgraded remaining rooms (~150) over a 3 month period including the mainplant controllers.
•Retained the more recently upgraded Alerton ABS 3.0 front end, removed all BCM-TUX globals and re-engineered DDC for completed BACnet system.
•Implemented supply air monitoring and fault diagnosis for suspect mechanical valve operation or control.
The system is now fully operational again, maintenance has a greater level of monitoring into the system. The main plant energy use is at an all time low due to a more sophisticated control system and smarter engineering.
