There's a greater awareness that a move into
energy-efficient buildings can neatly combine several interests of
a business – the financial, the human, and the
As of winter 2011, Clayton Utz will have a new home in Sydney in
1 Bligh St. As it is designed to achieve a 5 Star NABERS Energy
rating and has been awarded a 6 Star Green Star Office Design v2
Certified rating, the first such high-rise in Sydney, we think this
is a move which will do exactly that.
The green features of 1 Bligh Street
Our new home in 1 Bligh Street is built from sustainable
90% of the steel used comprises more than 50% recycled
the use of green concrete has meant that nearly 6,000 tonnes
of carbon dioxide have not been released into the atmosphere;
80% of the parts usually made from PVC have been replaced with
non-PVC materials; and
over 90% of the construction waste has been recycled.
Minimising the energy consumption through a double glass
For the first time on a high-rise building in Australia, 1 Bligh
Street will have a double glass façade – a skin
that not only lets in soft natural light, but also minimises the
building's energy consumption.
It does this by stopping direct sunlight from hitting the
internal glass. Between the inner and outer windows,
computer-controlled sun shades track the sun and automatically
adjust themselves. Air is also drawn in through natural convection
from lower vents, which further cools down the façade.
A better way to generate electricity
1 Bligh St uses an innovative tri-generation system. Gas and
solar energy will generate cooling, heating and electricity, which
could reduce our dependence on the electricity grid by up to
On top of the building, 500 square metres of roof-mounted solar
panels will capture solar energy to directly power an absorption
chiller to drive the cooling systems, an advanced hybrid of VAV and
chilled beam air conditioning technology.
... and to save water
The blackwater recycling technology uses waste water mined from
nearby sewer mains and the base building itself, and treats it to a
standard allowing it be used in toilets, cooling towers, and plant
This means that around 90% of the water demand will come from
recycled water, saving one Olympic size swimming pool of water
every two weeks.
What sorts of benefits do we think we'll
The first is the benefit to our people from having a healthier,
a more efficient air-conditioning system will give up to 150%
improvement in air flow over the code requirement, giving our
people more fresh air
60% of the floor plate is within 6 metres of the glass
façade and daylight, meaning we'll have more natural
light and be able to see more of the world outside; and
