Supplied and installed by building-control specialist P. A. Collacott & Co., the HVAC management system for the hotel and conference centre uses controllers, valves, sensors and a PC-based user interface — all from Honeywell.

A PC-based SymmetrE BMS interface provides operator access to all HVAC, water, extractor and heat-recovery plant for day-to-day monitoring and control. It enables hotel staff to set the environment in each meeting room, appropriately for the event. Energy can be saved by turning off heating or cooling to unused rooms.

HVAC plant is controlled by five Excel controllers in separate plant rooms across the complex.

The entire system uses a LonWorks open network, so it can be upgraded and expanded at any time in the future.

All banqueting and conference rooms have VAV fresh-air and extract-air system to provide ventilation and cooling. Each VAV system is served electrically from a starter and control panel in its associated plant room. Air flow rates are varied by controlling fan speeds using inverter drives next to the air-handling units.
