LED Building Upgrades
An LED lighting upgrade at Council’s Civic Centre and Melrose Park Depot is set to save over $307,000 over 10 years, modelling shows.
Installed in May 2020, the project cost $50,780 and was undertaken by Trade Services South Australia (TSSA).
The project has also eliminated 860 tonnes of greenhouse gas emissions over 10 years, responding to Council’s recent Climate Emergency Declaration and its pledge to join the Cities Power Partnership.
As part of the upgrade, 1,676 lights were replaced with LED lights that are approximately 85 per cent more efficient.
The upgrade has already received great feedback and will result in reduced maintenance costs and improved lighting levels.
Thanks to a State Government Retailer Energy Efficiency Scheme (REES) grant, the return on investment of the upgrade is projected to be 1.6 years.
Solar on Council Buildings
The City of Mitcham has installed a 30 KW Solar Photovoltaic system on the Civic Centre at 131 Belair Road, Torrens Park to provide clean energy and reduce costs. As part of Council’s strategic commitment to clean energy, we are exploring energy solutions that will reduce our environmental impact. The solar panel system will provide clean energy and deliver significant savings in annual power costs. The solar system is estimated to payback in 8.38 years with annual energy savings expected to be 43, 386 KwH. We anticipate this will result in greenhouse gas abatement of approximately 31.2 tonnes of CO2e annually. To date solar power has also been installed at the following Council managed sites over the last five years to provide clean energy and reduce costs:
- A 9 KW Solar PV system at the City of Mitcham Works Depot at Melrose Park
- A 6 KW Solar PV system at the Mitcham Heritage Research Centre
Between 2016 and 2018 a series of Level 2 energy audits were commissioned by Council focusing on City of Mitcham’s highest energy use sites, where a number of renewable energy (solar) and energy efficiency (LED lighting) opportunities emerged.
LED Street Lighting Upgrade
The City of Mitcham has upgraded 4,980 residential street lights to LED.
The new LED lights provide more directional light with less back spill and are 82% more energy efficient, reducing greenhouse gas emissions. The project has lowered Council greenhouse gas emissions by approximately 605 tonnes a year.
The $2.2 million project will be offset by projected savings (approximately $293,000 annually) in electricity charges, lower maintenance costs and reduced lighting tariffs.
Given the success of this project Council are now actively exploring the upgrade of remaining residential and open space lights to LED, which includes decorative and heritage street lights as well a diverse range of open space lighting.
