Extensive external shading all but eliminates
direct solar penetration into the building.
he Toyota WA Head Office is a dynamic
response to a brief for an office and
conference building that sits proudly in
the light industrial streetscape of Kewdale,
reflecting the environmental message and core
values of a sophisticated client and complementing
the existing Toyota facilities on the site.
The 1555sqm, two-storey design features
a facade of perforated aluminium blades to
provide a visually dynamic experience to passing
traffic whilst virtually eliminating direct solar
penetration to the building. The blades themselves
are individually aligned to enhance the sensation
of movement, an idea reflective of Toyota’s
‘Kaizan’ philosophy of continuous innovation.
The feature also keeps heat gain through the
facade to a minimum, allowing the highly
efficient building air conditioning systems to
further reduce energy consumption.
The work and public spaces have been
planned to allow staff to make best use of natural
ventilation and daylighting, which is predicted to
provide a comfortable interior environment for
60 per cent of the year without air-conditioning.
A key feature of the design is the strong
connection to the outdoor environment, with the
staff cafe facilities and conference lobby spaces
providing direct connections to the generous
Visitors to the building will be able to observe
exactly how much energy and water the building
is saving on a super-large LED display screen
in the lobby, and see how the good design and
exceptional internal environment minimises
energy consumption. Similarly, office workers
can get live feedback to see how their own
performance impacts on the energy efficiency
of the building.
