The Building Control System [BCS] provides central management and monitoring for air conditioning control, lighting control, and electrical and chilled water status monitoring, as well as providing energy management services.
The local area network system is based on a two tier LAN structure, where the primary network links the controllers to the command centre and the secondary LAN facilitates communication with the end devices. The BCS also interfaces to the life safety system, which is designed to override the BCS, in the event of an emergency.
The air conditioning requirements for the KLCC Development, including the Towers is served by a 30,000-ton chilled water plant District Cooling Centres which combines natural gas-driven cogeneration equipment with various forms of steam turbine-driven chillers and electric chillers.
The air-conditioning system selected for the Towers uses the latest development in floor-by-floor air handling units, utilising the chilled water. The floor-by-floor system solves the problems of acoustics, compactness, ease of maintenance and control.
This system also provides the most advanced approach to engineered smoke control. It allows for a pressure sandwich between the floor on fire and the adjacent floors, thus allowing the fire to be contained during the evacuation process.
The raised floor system utilised in the Towers allows for the effective flexible distribution of electric power and telecommunication cables to meet current and future needs.
