Sustainable Design features:

• Installed automatic blinds to keep out the eastern and western
  summer sun on the outside edge of the balconies approximately 2
  metres from the glass line, which shade the glass far more
  effectively than internal blinds, and still allow windows and
  doors to be opened, and easy access to the balcony.
• The strata units have opening windows which allow fresh air to
  be brought right through the building from one side to another.
• There is a continuous clerestory window along the whole of the
  roof top to extract air.
• The stairs and central spine of the building work as chimneys.
  They bring cool air through the building and take out hot air.
• Utilised fire stairs into black topped chimneys to extract hot
  air and create breezes throughout the building.
• Energy efficient air conditioning: each strata unit is fitted
  with its own individual Variable Speed Drive Reverse Cycle Air Con
  system. Each unit occupant has total control over how and when
  they operate their system, and because the power is individually
  metered, there is also a financial incentive for them to turn off
  their Air Con whenever possible and open the windows.
• Water and sewage: the water from the sewage treatment system
  is to be used for toilet flushing and the excess for drip
  irrigation to the gardens.  The average unit will save about
  15,350 litres of dam water a year
• Energy efficient lighting in offices, corridors and the car
  park
• Solar hot water
