When Holroyd City Council first started analysing its electricity usage, we found that the air conditioning was being left on longer than it needed to be and some windows were open during the day. By altering the operating times of the air-conditioning system and making sure all the windows in the administration building were shut, we reduced our carbon footprint and electricity bills, and improved the operation of the air conditioning system.
We also reviewed Council sites and determined which ones would be most suited to installing PV (solar power) systems. The suitability of each site depended on a number of factors such the orientation of the site, the condition of the roof, the positioning of trees, the time of day the site used most electricity and what rebates and credits were available at the time. We found that it was preferable and most suitable to put solar panels on the Council sites that use most of their electricity during the day when the PV systems would be generating the most power.
Council currently have PV systems at nine sites generating 91.29kW of electricity.

Energy Smart Cities and Homes Project
Holroyd City Council was successful in receiving funding from the Australian Government to implement Council's Energy Smart Cities and Homes Project. The energy efficiency works were implemented across seven Council owned facilities: Guildford West Children’s Centre, Greystanes Library, Merrylands Library, Wentworthville Library, Wenty Children’s Centre, Gumnut Grove Children’s Centre and the Banksia Babes Children’s Centre. Upgrades included energy efficient air conditioning replacement and lighting upgrades.
The project is expected to yield an annual energy reduction across the seven assets of 78,255 kWh and a reduction in greenhouse gas emissions associated with electricity consumption of 83tCO2-e, the equivalent of 166,000km and emissions savings of 94 return Sydney to Melbourne road trips per year.
Light Years Ahead Project
As part of a regional street light replacement project, Holroyd has replaced 940 old street lights with new energy efficient lights. These CO2 emission savings are equivalent to lighting over 4,800 homes each year over 20 years, taking nearly 900 cars off the road each year over 20 years, and heating and cooling over 1,900 Australian homes each year over 20 years.
Holroyd Council was one of nine Western Sydney councils to participate in the Light Years Ahead project. In total, approximately 13,000 old 80-watt mercury vapour street lights have been changed in residential streets across Western Sydney and replaced with new 18 watt LEDs. This action results in a 77% energy drop for each light changed. The new lights are making huge savings in terms of energy-costs and CO2 emissions ,with projected savings of over 74,000 tonnes of emissions and $21 million over 20 years for the 9 councils. The savings of CO2 are equivalent to taking around 37,000 cars off the road each year for 20 years or saving the emissions equivalent to lighting 92,500 average Aussie homes each year.
As Dorothea Mackellar said, “Australia is a land 'of droughts and flooding rains'”. For Sydney residents, this means we have to be prepared to experience times where water is plentiful and others where there are heavy water use restrictions.
When the Sydney region is experiencing long dry spells, everyone needs to work together to reduce their water consumption to make sure there is enough water to go around. A good way to do this is to begin implementing water saving actions even when there are no water use restrictions. Some things to think about is purchasing a water-efficient washing machine and dishwasher when the old ones stop working. Installing water-efficient taps, showers and toilets are also great ways to save water.
In a great majority of Sydney homes, gardens account for the largest proportion of water usage. By planting drought-proof plants native to the Holroyd area, and drought tolerant grasses, you can greatly reduce your garden's water consumption.
We also support other environmental programs like Fridge buyback and Close the loop.
