Basement ventilation is provided by large
vertical extraction fans in vertical shafts with
modulating dampers on every level, modulating
to maintain minimum levels of carbon monoxide
on each parking level. Each extraction fan has a
variable speed drive to use only the necessary
energy. Furthermore, make-up air is introduced
from the upper levels and supplied to all levels
below through ramps and a series of dedicated
slab cut-outs with mentis grid over, so as to avoid
58
energy and space wastage from make-up air fans.
A central Building Management System (BMS)
controls and monitors all HVAC systems via an
intuitive user interface. Other services such as
domestic water, elevators, fire panels, UPS
systems, generators and energy meters are also
monitored via the BMS. The system is used as
an invaluable tool for building fine tuning through
the use of logged trends and active monitoring of
real-time cooling energy efficiency ratios.
