and defined beam angles. The result is a high im-
pact, low energy design with minimal spill light. To
conform to Green Building requirements, the fins
are also angled slightly downwards, preventing the
LEDs from creating sky glow.
The ‘clip-in’ installation method of the LED strips
allows them to be replaced easily if required (there
are no mechanical fixings on the outside of the
building). The power supplies that feed the strips
are all housed remotely within the central lobbies
on each floor of the building. This results in ease
of access as the lifespan of the power supplies is
generally less than those of the LEDs.
Since the aim of the façade lighting installation
was to accentuate and complement the various
façade images, or topographical references, being
portrayed, the layout of the LEDs was dictated by
the outline of each image, so the ‘story’ being told
could be appreciated during daylight hours as well
as at night.
Landscape/public open space
The second area of importance to be addressed
was the public open space at the main entrance/
piazza area. The intention for this space was to be
vibrant and inviting, whilst ‘reinforcing’ the linear
feel of the various façades.The lighting design was
limited to various pockets or areas of use, with the
balance of circulation spaces relying on spill light
from the surrounding areas. With the exception of
a few fittings, all the lighting elements in this area
were also LED. The combination of warm white,
visible, vertical linear LED elements and concealed
LEDs under stairs and timber decks creates a suffi-
ciently lit space for evening use, which successfully
acknowledges the design intention.
This vibrant public space is enclosed at high
level with a canopy or ‘eyebrow’ that embraces
the space. As a slight contrast, cool white LEDs
have been used on the eyebrow to define it above
the warmly lit public space and to allow visitors to
clearly read the two very different elements at night.
The lighting intentions for the façades and the
public space have both been effectively achieved.
The building and image-depicting façades are
clearly visible at night and from every main freeway
into the CBD. People are drawn into the public
open space, and it is a hustle and bustle of activ-
ity from early morning until late at night, with the
combination of striking and subtle lighting effects
complementing the vibrant activities and overall
lighting design.
