Honeywell Excel 5000 Series controllers and Honeywell field devices are at the heart of the building management system in the UK’s tallest public viewing tower, the 170 metre Spinnaker Tower in Portsmouth.
The design and installation by Smith & Byford were both problem-free and were assisted by the ease with which Smith & Byford (a Honeywell Solutions Partner based in Cheam, Surrey) was able to design and input the applications for the Honeywell Excel controllers, which deliver energy-efficiency, cost control and comfort.
The systems control the HVAC in the tower’s two enclosed viewing platforms and its base building which houses a reception area, café, shop and offices. Two air handling units serve the view decks, five serve the base building.
The Building Management System incorporates a UPS (uninterruptible power supply) to maintain power to the Excel control system should the mains power fail. The controls then ensure all priority services are restored without delay when the tower’s diesel generator is on line. The BMS includes interlocks with alarm systems, such as lift failure, intruder detection and fire alerting, as well as fire extinguishing.
