ANZ

ANZ new workplace in Melbourne's Docklands precinct will reflect ANZ's commitment to reduce its environmental impact.

The building, due for completion in 2009, will be the largest single tenanted office building in Australia. It is registered with the Green Building Council of Australia for an office rating and we are aiming for the highest
currently available rating. This design includes stormwater re-use, water recycling, wind turbines, the use of Yarra River water in the building's cooling system and greater use of natural light.

Key 'green' features of our new building:

		River cooling - Water from the Yarra River will be used to release excess heat from the air conditioning system, which reduces water and energy consumption. The water will be cooled prior to being returned to the river.
		Underfloor air conditioning - 100% 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.
		Solar power - Solar cells will be used on the north-facing roof to generate 170,000kW hours per year, reducing greenhouse emissions by more than 220 tonnes per year.
		Wind turbines - Wind turbines on the north-facing roof of the building will generate 10,000kW hours of electricity per year.
		Tri-generation plant - Natural gas used to simultaneously generate electricity, heat and cooling. The plant will also feed air conditioning absorption chillers in summer and boilers for heating in winter.
		Landscaped green roof garden - 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.
		Stormwater reuse - Rainwater collected from the roof will be used to irrigate the green roof garden.
		Grey and black water recycling - All waste water will be recycled for use in landscape irrigation, toilet flushing and cooling towers.
		Passive sun shading - Exterior sun shading to maximise daylight and reduce heat gain and loss.
