Quick Notes

Sector: Commercial

Contract Type: BMS

Client: Ibis Hotel

Project Year: March 2016

The background

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.

Challenges

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.

Our solution

  • 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 Result

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.
