Energy efficiency improvements - Rose Gums Wilderness Retreat

Date

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. 

Energy efficiency improvements - Hidden Valley Cabins

Date

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. 

Energy efficiency improvements - The Ship Inn

Date

When a customer pointed out the unsustainability of this hospitality venue’s food offerings, the business began a move towards greater energy efficiency that led to a 21% reduction in annual energy usage. The move, which also shaved $10,785 a year off the businesses costs (including through savings in waste and water management) involved changes in lighting, a shift to preferencing local and seasonal products and training of staff to support energy efficiency activities. 

Energy-efficient equipment - Golden North

Date

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.

Reducing energy use - The Good Loaf Sourdough Bakery & Cafe

Date

The owners of Bendigo’s The Good Loaf Sourdough Bakery & Café regularly review the businesses energy practices. This factsheet details a number of changes made in the last few years, which included:

  • installing energy-efficient compact fluorescent lamps (CFLs)
  • a timer on the baking oven
  • zoning the bakery’s lighting 

These changes, and others detailed in this factsheet, have meant that despite the business growing 10% in recent years, energy costs have remained stable. A cost saving of $2000 per annum.

Energy use reduction - McIvor Road Vet Clinic

Date

At the McIvor Road Vet Clinic in Victoria, an increase in demand for its services led to installation of new equipment. Energy bills went ‘through the roof’, and service demands meant switching equipment off was not an option. Instead, the Clinic installed additional insulation and a 10kW solar PV system, switched from halogen to light emitting diodes (LEDs), and installed a solar boosted, gas hot water system. Within 12 months, the Clinic’s energy use has been cut by 50%, saving $5000 per annum.

Energy efficiency gains reduce electricity use - The Manly Hotel

Brisbane’s Manly Hotel was able to save 873,188 MJ of energy (a $20,000 saving for the  business) by focusing on energy efficiency. This case study highlights where savings were made: most came through the installation of energy-efficient equipment, including power factor correction equipment; upgrades to air conditioners and televisions and replacing halogen globes with light emitting diodes (LEDs).  The business also reduced hot water temperatures by 10°C. 

Energy assessment and equipment upgrades reduces energy use - Majors SUPA IGA

Date

Major’s SUPA IGA has served its community for more than 100 years.  The owners have implemented numerous energy efficiency measures including airlocking the store entrance - creating a thermal barrier, by installing a second door, reduces air exchange between external and internal areas of the store, and cuts the heating, cooling and refrigeration load. Upgrading the heating and cooling system - installing variable speed drives to the heat pump and upgrading the cooling tower to a compressed condenser with high efficiency fans to reduce energy input to energy output requirements and increas
