About The Project

The iconic Central Park urban renewal precinct is an 11-building development near Central Station/Broadway, on the edge of Sydney’s CBD. It includes 2,200 residential apartments and 20,000 sqm of retail space. In keeping with its principle of sustainability, and to improve its NABERS rating, the precinct is serviced by a central tri-generation plant. Tri-generation uses natural gas to power a gas engine to produce electricity. The waste heat from this engine is used to provide hot water, which replaces hot water produced by conventional means. Through the installation of absorption chillers, it provides chilled water for air conditioning.

CNF was engaged to:

  • Provide engineering expertise during the design and construction phase of Central Park 2.
  • Provide expert technical advice during the tendering and construction phase to ensure specification compliance and quality assurance.
  • Ensure the systems would integrate into Central Park 1 and deliver the targeted setpoints during the design phase.
