PROJECT

300 George Street is a mixed-use development, comprising of a 46,000m² NLA commercial office tower, 82 storey 65,000m² residential tower and a five-star world class hotel, 2 levels of premium retail & restaurants & a 7 level 900 car basement carpark on the former site of the Supreme Court and the District Court.

SPECIAL ENGINEERING FEATURES

• A key component of the low energy services design is central energy plant innovatively integrated into the office tower. Serving the cooling needs of the entire precinct, the central plant solution realises economies of scale to reduce total plant space and cost, and takes advantage of diversity between the various development components to maximise plant utilisation and efficiency.
• Project ESD initiatives have been selected to be cost effective and practicable for the application and sub-tropical location, and include:
  • High performance low-e double glazed facades;
  • Optimised Low Temperature Variable Air Volume air conditioning systems;
  • Addressable LED lighting achieving high indoor environment quality and low energy consumption;
  • Active transport facilities;
  • Building life cycle analysis and sustainable materials selection;
  • Rainwater and condensate harvesting.
• The precinct power supply is via a 10 transformer on site supply authority substation.
• The design includes a central standby power plant which services all the uses on the site. The standby plant consists of 2 medium sized and 1 large sized diesel generators that operate in parallel. The control system determines how many generators are required to support the load and shuts down or starts up the required generators. The control system also synchronises the generators with the mains supply at each of the 8 switchboards provided with a standby supply for a no loss return to mains.
