Shop/mall ventilation system
There are four central fresh air plants, each with three fresh
air units that provide filtered, un-conditioned fresh air to
the central shop and mall walkway areas. Filtered fresh air
is distributed to the central zones through galvanised sheet
metal ducts routed above the shop ceilings. These common
ventilation systems can also be used in reverse for smoke
clearance. Ablution blocks are mechanically ventilated with
dedicated extraction systems.
Parking area ventilation system
The parking areas are mechanically ventilated. These systems
are also used as a smoke clearance system, together with the
use of jet/trust fans.
