Radevski Coolstores in the Goulburn Valley Victoria is a major supplier of apples and pears to Coles. It undertook a $1.15 million upgrade of 2 cool store systems, to allow the plant to operate on ammonia as a refrigerant, and to use condenser fan speed control (using variable speed drives) to further improve performance. The results were significant: one site recorded 60% reduction in its maximum electrical demand, and the upgrades will cut the company’s energy costs by 25%.
UnitingCare Community is a Queensland-based provider of community services. After energy audits were completed on a number of its 297 properties, the organisation began energy efficiency improvements as one of its first initiative. At Gipps Street, electricity consumption was high relative to floor area, until changes were made.
When the Multicultural Services Centre of WA conducted an energy audit, air conditioning showed up as a large cost for the community services organisation. Numerous savings have been made since implementing recommendations like: adjusting thermostats to 22°C in winter, and 20°C in summer; regular cleaning of vents, ducts and skylights; task specific cooling via ceiling fans or portable fans; replacing florescent lighting with light emitting diodes (LEDs).
The St Ambrose Church (and its two attached houses) has been part of the Brunswick community for over 140 years. It recently: installed greywater and rainwater systems, insulating ceilings, replaced electric heating with 5 star gas central heating, upgraded lighting, and purchased 100% GreenPower, and has numerous other plans to continue making savings and reducing its environmental footprint.
Generations Church, just north of Cairns, comprises a large hall, served by a large commercial chiller unit; a number of small rooms and offices (all with wall air conditioners) and an adjacent building with toilets, kitchen and a community room. An energy assessment show that for an investment of $2550, the top five opportunities to save could be implemented, bringing projected annual savings of $1430.
Aquatic Centres use an enormous amount of energy. But with efficiency measures, YMCA Spark pilot site Peter Krenz Aquatic Centre managed to cut electricity use by 8.5% and identified opportunities to save a further 20%. This Aquatic Centre found that by being more energy efficient and making some smart energy investments, they could have a reduction off their energy bills of at least $30,000 per year.
The ‘Watts in Your Business’ project conducted by Apple and Pear Australia Ltd completed energy audits of 30 packhouses and orchards Australia-wide. This fact sheet shows how grading equipment changes can cut energy use and save money.

At Carlton’s Café Lua, a local program helped inspire a range of sustainability improvements. These include switching to compostable take away cups, installing water-saving tap aerators, installing energy-efficient lighting and installing louvre windows for ventilation – a move which reduces the need for energy intensive air conditioning.
At sustainable architecture practice Breathe Architecture, the company applies the principles it uses to help clients create buildings with lighter footprints to its own office. Insulation, fans and smart design of window placement draw cool air in and push hot air out, negating the need for air conditioning. Amongst other things: second-hand furniture and fittings save money and carbon emissions, and staff are given a sustainability induction to discuss these and other measures in place.
