Chilled Beam
The chilled beam consists of chilled copper tubes looped through a metal
structure. The tube tie into chilled water supply and return lines running in
the cavities behind the precast concrete panel.

SHOWER TOWER
‘Shower towers’ on the south side of the building act
like passive cooling towers – air and water gently falls
to provide extra cool water for building reticulation
and cool air to supplement ground floor and retail

FAÇADE MATERIALS
BARK FAÇADE
The eastern core and façade used the analogy of bark. It was conceived as a
protective layer that filtered light and air into the naturally ventilated wet
area spaces behind. The final solution consists of two overlapping layers
of perforated metal with polycarbonate walling and fixed metal louvres.

FAÇADE MATERIALS
TIMBER LOUVERS
A louvers system covering the western façade with timbre
louvers able to move and photovoltaic cell to ‘track’ the sun
and glare, responding in the internal light conditions and air
quality. Timber louvers are made by recycled timber.

WINDOWS
TAPERING WINDOWS
This to reduce the heat at upper levels.
