While most of us associate Central Park with New York City, there’s another Central Park making its mark in the heart of Sydney, Australia. Sydney’s Central Park is a multistage $2 billion urban village that uses heating, cooling and electricity – trigeneration – from Brookfield Energy Australia. (Brookfield is our parent company.)
The sustainably designed, mainly residential Central Park is being developed in phases across an 8- to 10-year time span by a team of world-leading architects from Sydney, London, Paris and Copenhagen. One Central Park was phase one (shown in photo); all phases will use Brookfield Energy Australia’s trigeneration service.
In addition, Brookfield will soon expand its chilled-water system to air condition buildings at the nearby University of Technology Sydney (OTS). According to a September 2016 article on the Pyrmont Ultimo Chamber of Commerce web site, Sydney Lord Mayor Clover Moore cited the move as a way forward for sustainable energy: “It’s great news the network is now expanding across the road to UTS, and we hope to see other businesses and building owners in the area take advantage of the environmental efficiencies and cost savings district energy can bring. With 80 percent of greenhouse gas emissions in the City of Sydney coming from buildings, it’s important we keep looking for innovative ways to create sustainable, energy efficient developments.”
The Fifth Estate reports that Brookfield’s district cooling system will help UTS cut its greenhouse gas emissions by 2.2 percent or 1,111 tonnes per year. UTS Green Infrastructure Project Manager Jonathan Prendergast said district cooling will help UTS save capital, too: “Investment in new chilling infrastructure can be capital- and space-intensive, requiring new chilling plant, pumps, connecting pipework, cooling towers and electrical infrastructure. By procuring a portion of UTS’s cooling from an offsite supplier, UTS can invest in its core business and free up space for teaching, officers and a more active roof space without cooling towers.”
The Fifth Estate notes that the different peak-use periods for educational and residential space improved the project’s feasibility. Residential use is highest in the evenings and on weekends; educational use is highest during weekdays.
UTS signed a 15-year cooling contract for chilled water, with service slated to start in 2018.
