Sydney’s Goulburn Street Car Park has converted its 850 fluorescent lights to light emitting diodes (LEDs). The lighting upgrade is forecast to reduce greenhouse gas emissions by 220 tonnes per year and save 206 mWh of electricity per year (the equivalent energy used by 28 typical Sydney households annually) equivalent to approximately $26,000 pa.
A trial of the LED lighting was conducted in the car park in February 2010, proving that light levels exceeded the Australian Standard for car park lighting and resulted in a 62% reduction in electricity. During the trial, savings increased a further 6% with the introduction of a daylight switching feature, whereby the LED lights around the perimeter of the car park switch off after sensing sufficient natural lighting.
A great green step for the Goulburn Street car park and for the City of Sydney in their effort to save on car park operating costs.
