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.
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
Located at the southern tip of the Great Barrier Reef, Lady Elliott Island Eco Resort has done extensive work reducing its energy consumption. Changes have yielded a 3.5 year payback, and saved $270,000 a year in fuel costs. This factsheet explains many of the resort’s initiatives, including its work promoting energy efficiency to guests.
The Glebe Point youth hostel in Sydney has saved $960 a year through moving to more efficient lighting options. Actions have includes replacing rooftop para floods with compact fluorescent lamp (CFL) flood lights; replacing 50 watt (W) down lights with 35W IRC halogen down lights; installation of fluorescent T5 conversion kits across the property; and replacing electric clothes dryers with gas units.
Energy efficiency improvements at the Mackay based Cape Hillsborough Nature Resort have led to savings of over $30,000 a year (including savings made through waste and water management). This family-owned business has – amongst other changes – replaced its six gas-fired hot water systems with four heat pump systems, changed all lighting to energy efficient globes, and installed sensor lights where practical.
Located in Goondiwindi, Queensland Chesterfield Australia is an Agricultural and Construction Equipment company. The Goondiwindi site has both workshop and a retail spaces requiring specific lighting. During the Financial Years 2012/13, the facility consumed 119,984 kilowatt hours (kWh) of electricity, emitting 103 tonnes of carbon. An energy audit identified potential energy efficiency cost savings of approximately $6605 a year using light emitting diodes (LEDs) upgrades, with a payback period of just 2.2 years.
Queensland Murray Darling Committee Inc (QMDC) completed an energy audit on an aged care facility near Warwick, Queensland. The retirement home consists of single level accommodation buildings and the capacity to accommodate 40 residents. During the Financial Years 2012/13, the facility consumed 114,467 kWh of electricity, emitting 98 tonnes of carbon. An energy audit identified potential energy efficiency cost savings worth approximately $4,257 per annum with an average payback period of 3.1 years.
The Woodburn Orchard’s facility in Batlow New South Wales produces and packs around 4000 tonnes of apples a year. Woodburn is classified as a large enterprise when compared to other orchards that were audited.
The Alto Hotel on Bourke in inner city Melbourne aims to lead its field in energy efficiency practices. Changes are extensive and have included equipping air conditioning with inverter and moment sensor technology (an $8000 saving); finding ways to optimise heating in an heritage building (solutions include staggered stud wall systems, multiple layers of floor coverings, and heat reflecting, double glazed windows). This factsheet outlines many of the 4-star hotel’s initiatives to bring energy efficiency to the front of its business model.
At Capilano’s Richlands honey production facility, electricity and natural gas are the primary energy sources and input costs. Of the 18,000 gigajoule (GJ) (a cost of $580,000) used on site, 25% is used by thermal loads of pasteurisation and hot water generation. An assessment took into consideration upcoming business changes (the build of a new facility was pending) and advised Capilano about opportunities to save money on lighting, solar PV, thermal system insulation and heat recovery, and compressed air heat recovery.
