Customs House, Sydney

14 May 2012 – The City of Sydney has appointed Origin Energy to be lead contractor on a major overhaul of its 45 properties to make them more energy and water efficient, ahead of the rollout of the city’s trigeneration network, also by Origin.

The two-year $6.9 million project is designed to tackle energy demand as a first step in the trigen plans, with expected energy savings to shave more than $1 million from yearly energy bills and about $200,000 from water bills.

Work will include Town Hall House, Customs House, pools, community centres, libraries and car parks across the city and will include:

  • Replacement of lighting in Customs House
  • Upgrade to heating and airconditioning systems at Sydney Town Hall, Ultimo Community Centre and Victoria Park Pool to use less energy
  • centralised power management systems for computers
  • voltage reduction units to slash electricity use by pumps, fans and lights

“Retrofitting our buildings with energy and water efficiency technologies will cut our costs, and deliver almost triple the reduction in the City’s carbon emissions, from 6.8 to 19.9 per cent,” Ms Moore said.

Electricity use would be cut by about 6.4 million kilowatt hours, “enough to supply about 870 households a year, and save an estimated $880,000 a year in power bills.”

Origin will outsource water savings work to Ecosave, which will install aerated taps and shower heads, cistern modifiers in toilets and waterless urinals as part of its contribution.

Water consumption is expected to fall by 53,300 kilolitres a year, enough to supply nearly 300 households and reduce maintenance and carbon pollution costs.

Origin won the work after a tender process and a council statement said nergy and water performance guarantees would be independently verified.

Work is expected to be carried out without any closures of facilities.

“The City of Sydney is Australia’s first officially certified carbon neutral government. The City’s 2030 target to reduce carbon emissions by 70 per cent is one of the most ambitious targets of any Australian government,” the council said.
