After cutting energy use in its own buildings by 20 percent, the City of Sydney is working out how much energy could be saved across all buildings in Sydney.
City of Sydney has signed a contract with pitt&sherry and Exergy Australia to calculate the greenhouse gas emissions that could be cut by city-wide energy efficiency measures. Lord Mayor Clover Moore says it will be the most comprehensive assessment of the energy efficiency potential of the city’s building stock ever undertaken.
“We’ve cut 20 percent of energy use in our own buildings,” the Lord Mayor notes. “The challenge now is to make similar or greater savings across the entire city. This plan will show building owners and their tenants just how much they can save on power bills by reducing energy use.”
The work, which will form the basis for a new energy efficiency master plan for Australia’s global capital, will look at all building sectors including residential, commercial and small business.
Between 2009 and 2012, energy efficiency retrofits of the city’s own buildings reduced greenhouse gas emissions by 20 percent. By upgrading lighting, updating air-conditioning plants, upgrading power management systems on personal computers, installing movement sensors and implementing numerous other measures, the city has saved $880,000 a year on its electricity bills.
The city already works in close partnership with residents and business saving energy with programs including Smart Green Apartments, CitySwitch Green Office and the Better Buildings Partnership. Many of those who have cut energy use under these programs will be part of the new plan and have a chance to explain the regulatory barriers that can make saving energy difficult.
Phil Harrington, principal carbon and energy consultant at pitt&sherry, states that the master plan would help the city reach its target of cutting emissions in central Sydney by 70 percent by 2030.
Complementary plans detail the city’s proposals for a network of trigeneration plants (adopted at council’s last meeting) and a renewable energy master plan (on public exhibition) that could result in the city’s electricity, heating and cooling demands being met by 100 percent renewable energy by 2030.
