ANZ

ANZ's new workplace at 833 Collins Street in Melbourne's Docklands precinct will reflect ANZ's commitment to reducing its environmental impact.

The workplace is the largest, greenest commercial office building currently under construction in Australia. It will be home to over 6,500 ANZ staff and is due for completion in late 2009.

ANZ has committed to implementing a number of leading green initiatives in the building that will see it recognised as one of the world's most environmentally progressive workplaces in the financial sector. The building is registered for a Green Star rating with the Green Building Council of Australia for the categories 'Office as Built', 'Office Interiors' and 'Office Design'.

Key environmental features of the building:

		River cooling - Cool water from the river is piped through the building where the temperature differential is used to cool the water of the air conditioning system reducing the demand on the cooling towers. The river cooling system will significantly reduce the amount of water required to operate the building.
		Tri-generation plant - Generation of on-site electricity using natural gas instead of brown coal which has a significantly higher carbon intensity. The heat from the process feeds the air conditioning absorption chillers in the summer and the boilers for heating in the winter.
		Solar power - 1000m2 of solar cells will be installed on the roof of the building supplying clean, renewable electricity.
		Blackwater recycling - All waste water will be recycled for use in landscape irrigation, toilet flushing and cooling towers.
		Wind turbines - roof mounted wind turbines will further supplement the electricity being generated on site for use within the building.
		Stormwater reuse - Rainwater from the upper roof area of the building will be retained and collected in a tank for irrigation of the lower green roof and other landscaped areas in conjunction with the water from the blackwater recycling plant.
		Green roof - Low-growing, drought-tolerant species on the lower roof adjacent to the Yarra River will create a 'cool zone' which returns oxygen to the air.
		Underfloor air conditioning - Energy efficient air conditioning system maximising the use of fresh air and provide a healthy working environment. Fresh air will be supplied through a raised floor system and then extracted through the roof. Air quality is improved because the air is not recirculated throughout the building. Energy is saved as the air is not required to be cooled to the extent of conventional systems.
