District cooling to backbone landmark Sydney urban renewal project

Date: 21 January 2015

Lend Lease has awarded district energy specialist, Veolia, a long term contract to operate and maintain one of Australia’s largest district energy, cooling and water treatment schemes at Barangaroo South in Sydney, New South Wales.

The contract will involve the operations and maintenance of a 62 MW district cooling network, high voltage embedded electrical network and a recycled water treatment plant.

Designed and built by Lend Lease, this shared infrastructure will be critical to ensuring a carbon neutral and water positive outcome at this commercial precinct.

The first stage of the Barangaroo South project, comprising of commercial, residential and retail buildings will start to be occupied from mid-2015. The operation and maintenance of the precinct wide cooling plant by Veolia will ensure optimal thermal comfort for residents, tenants and visitors of the precinct at all times.

Veolia will achieve this comfort through the provision of cooling in the form of cold water supplied from a single central chiller plant. This centralised solution will allow for better utilisation of the commercial space due to the elimination of individual air-conditioning plants for each building within the development, electrical demand and greenhouse gas emissions. Further, this district wide chiller plant will be cooled by sea water from Sydney Harbour, reducing electrical demand and greenhouse gas emissions.

Andrew Wilson, Managing Director Barangaroo South said: “We have a clear vision for Barangaroo South to be the first carbon neutral precinct of its size in Australia and for it also to be a water positive development. The use of shared infrastructure, water recycling and harbour cooling are key components in meeting these ambitions.”

Barangaroo South is one of the largest urban renewal projects in Sydney for a generation and one of the most significant waterfront transformations currently underway anywhere in the world.
