Retrofit of Sydney buildings to save City $1m a year

from City of Sydney Press Release, dated 14 May 2012

A major overhaul has started on the City of Sydney’s 45 properties, which will make them more energy and water efficient, saving more than $1 million a year on bills.

Lord Mayor Clover Moore said the two year $6.9 million project would include Town Hall House, Customs House, pools, community centres, libraries and car parks across the city.

Old and energy inefficient lights are being replaced at Customs House this week while heating and airconditioning systems at Sydney Town Hall, Ultimo Community Centre and Victoria Park Pool are being upgraded so they use less energy.

“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,” said the Lord Mayor.

“Our approach is to show by doing – we’re showing you can cut bottom line costs and seriously reduce your impact on the environment. It’s a win-win.”

The buildings will be fitted with energy efficient lighting, air-conditioning and heating, centralised power management systems for computers and voltage reduction units to slash electricity use by pumps, fans and lights.

The retrofit will cut electricity use by about 6.4 million kilowatt hours (kWh) a year, enough to supply about 870 households a year, and save an estimated $880,000 a year in power bills.

Water-saving devices include aerated taps and shower heads, cistern modifiers in toilets and waterless urinals. Water consumption will fall by about 53,300 kilolitres a year, enough to supply nearly 300 households and save about $200,000 a year. The retrofit will also reduce maintenance and carbon pollution costs.

After a tender process, the Council approved Origin Energy, the leading Australian integrated energy company, to deliver this innovative program of work. The energy and water performance guarantees will be independently verified.

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.
