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 community.
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 construction materials:
Minimising the energy consumption through a double glass façade
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 25%.
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 irrigation.
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 gain?
The first is the benefit to our people from having a healthier, brighter environment:
