The not-for-profit organisation, Arts Project Australia, provides an inner city studio and gallery to nurture and promote artists with an intellectual disability. Owning the building makes environment actions even more compelling, so when an audit helped clarify priorities, the organisation got started. It installed double-glazed and operable windows, replaced halogens with light emitting diodes (LEDs), and switched power companies. Their first bill after the changes was $1200 less than usual.
When the Alto Hotel was built in 2006, sustainability features were built into the design. Today, the hotel achieves outstanding savings in energy, waste and water use. While these features added approximately $450,000 to the $5 million build, savings on electricity, water, gas and chemicals are estimated at $50,000 per annum, and creates a point of different for customers.
At the Albion Budget Supermarket in Brunswick West Melbourne a public event helped provide funds for sustainability improvements. Called a ‘Carrotmob’, this event promises businesses a ‘mob’ of consumers in exchange for the business owner spending some of that additional revenue on sustainability improvements. The $700 raised at this event covered the cost of replacing half the supermarkets existing lights with more efficient T5 fluorescent tubes. In turn, that has saved the owners money. The supermarket is on track to save over $600 in electricity costs every year.
Newcastle French Hot Bread, a busy bakery and café in Newcastle in NSW, used an action plan to gradually implement the improvements suggested by a local energy assessor. Changes included maintenance and repair of seals on oven doors, using an off-peak timer for the electric hot water system, and separating lights to different circuits, allowing for zoning. A bill analysis also showed they’d been overcharged by their energy retailer: working via the Ombudsman recovered the business $30,000.
At Bendigo’s Indulge Fine Belgian Chocolates, energy efficiency improvements began with behaviour change: at night, all lights are switched and electric hot water is unplugged. Next, the owner installed light emitting diodes (LEDs), an energy-efficient refrigerator, never ran the air conditioner at less than 25°C degrees, and used excess heat from machinery to replace the store’s reverse cycle heater in winter. These combined actions mean that despite the business growing 20% in the last 4 years, its energy consumption has stayed still; a cost saving of $1600 per annum.
When an energy assessment clearly showed the owners of Victoria’s Central Kitchens where its energy was going, the company set about reducing its costs by: upgrading to an energy efficient air compressor; introducing better start-up and shut-down procedures; replacing halogen lights with compact flurorescent lamps (CFLs) and light emitting diodes (LEDs), installing timer buttons in toilets; fitting timers and exhaust fans to the drink machines and installing CFLs to its high bay.
After an audit helped the owners of Berwicks Office Technology reduce energy costs in its 900 sqm building in Brisbane’s West End. Upgrading to a new digital metering system helped Berwicks to track spikes in energy use, while upgrading lighting made the parking garage safer and more energy efficient. It also led the company to replace its 200 fluorescent tubes with light emitting diodes (LEDs), resulting in a better visual experience for customers and staff, as well as reducing its electricity needs by around 30,000 kilowatt hours (kWh) a year.
At Rose Gum Wilderness retreat in Queensland a number of energy efficiency improvements have been made. This case study outlines some of the changes, which include installation of gas hot water units; installation of eco-efficient lighting and appliances; and a number of initiatives encouraging guests to engage with the company’s energy efficiency focus.
At Hidden Valley, 1.5 hours out of Townsville, rising diesel prices prompted this accommodation provider to improve their businesses energy efficiency. This case study details some of their actions, including changing traditional light bulbs for energy-saving compact fluorescents, and replacing fridges with more energy-efficient models.
Golden North is a manufacturer of premium ice cream and frozen yoghurt. Its South Australian facility at Laura consumes 6930 gigajoules (GJ) of electricity per annum, about 75% of which is used by the refrigeration plant. Energy assessment identified numerous areas for savings through energy efficiency improvements, including replacing inefficient compressors with a single crew compressor (and using variable speed drives to ensure it runs efficiently); installation of hot water exchangers for oil cooling and installing variable speed fans.
