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.
Keech Australia has been designing and manufacturing high integrity steel castings for almost 80 years. Its carbon reduction strategy, started in 2010 aims, to reduce Keech’s carbon intensity but up to 30%, improve yield and competitiveness, and reduce productivity costs by 20%. This case study details the changes Keech Australia has made to meet these goals.
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.
At Goldfields Revegetation, a specialised plant nursery in Victoria’s Mandurang, the owners had a goal of reducing the company’s energy consumption by 30%. An energy assessment proved up to 70% savings were possible, and would save the company $6000 per annum. Reductions came from: replacing 50W halogens with energy efficient 35W halogens; installing motion sensors on external flood lights; fitting a timer to the electric hot water system; installing 1.6kW solar PV system; and numerous behaviour changes.
When e+ architecture’s ownership wanted to cut its rising energy costs, they got their team onboard making simple behaviour changes. Then, they changed lighting to more energy efficient options; installed timers to the electric hot water system; installed a 1.6kW PV system and began purchasing 10% Green Power. The combined actions saved the company $2025 a year, reducing its energy bills by 46% in 12 months.
The owners of the Chocolate Lily Sustainable Stays B&B in Sedgwick wanted to incorporate as many energy efficiency practices as possible into their property. They significantly reduced their heating, cooling and energy costs by: installing low energy CFLs; installing R3.5 insulation; fitting double glazing windows; using a heat pump to provide hot water; installing a 3.32kW solar PV system; using solar to heat the outdoor pool; and using 100% Green Power for top-ups.
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.
At Bendigo Community Health Services an energy assessment became the starting point for knowing how to reduce the organisation’s overall energy use. The result, implemented via Green Teams, saw a 6.1% energy reduction and annual savings of $5000, mostly thanks to: implementing a behaviour change program, changing how air conditioners were used; installing timers on hot water units; installing solar panels and replacing fluorescent tubes with light emitting diodes (LEDs) and solar tubes.
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.
