Tridium takes control at world’s tallest apartment block

Integrating over 4000 control points in the 21st Century Tower in Dubai is a Tridium Niagara Framework system.
The world’s tallest apartment block, the 21st Century Tower in Dubai, is the latest development to feature a web-serving building-services control solution from Tridium. The 53-storey tower is 269 m high and uses Tridium’s Niagara Framework to integrate its complex range of building-services equipment. Services designed to run on BACnet, LonWorks and Modbus control bus networks are connected in a single, open, interoperable and remotely accessible web-based control environment. There is no need for gateways, complex programming or expensive BMS supervisors. The tower has 400 apartments offering over 71 000 m2 of living space. Over 1800 locally controlled fan-coil units fed with chilled water via a variable-flow system provide comfort cooling. Air-handling plant, pump, power, fire detection and other services are distributed throughout plantrooms on five levels. The adjacent 9-storey car park houses five 1840 kW chillers, cooling towers, additional pumps and electrical substations. The Niagara Framework integrates an array of multi-vendor control sub-systems comprising over 4000 points into one network. The work was carried out by Pacific Controls of Dubai. The Carrier chillers and the Simplex fire-alarm system are controlled by devices using the BACnet system. The 15 Honeywell HVAC outstations, ASTI access-control system and CEAG emergency-lighting control system operate on LonWorks. Schneider Electric power-monitoring units and FG Wilson generations work on the Modbus communication protocol. There is also a Vicon CCTV system using TCP/IP. The Niagara Framework talks to each controller in its native protocol. The client was The Al Rostamani Group. Consultants were W. S. Atkins (UK) Overseas, and M&E contractor was the Emirates Trading Agency.
