HVAC factsheet - The importance of cleaning coils
Demonstrates the importance of keeping condenser and evaporator coils clean in HVAC systems.
HVAC factsheet - Thermal storage
Provides some basic information on thermal storage including a description of sensible heat, latent heat and thermo-chemical storage and how these may apply to chiller operation through load leveling and load shifting strategies.
HVAC factsheet - Wireless metering
Summarises the HVAC HESS wireless metering report released in January 2012 that demonstrates the benefits of retrofitting wireless metering to existing buildings.
Implementing energy efficiency and sustainability measures - Cafe Lua
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.

Installing fridge timers saves energy and money - Bottle King Liquor
The average small-medium retail business can use 80,000 kilowatt hours (kWh) of electricity a year. This factsheet shows how one business, Bottle King Liquor, saved on energy costs to run its fridges. By installing fridge timers, the business saved $135 a year for the running costs of each of its 7 drinks fridges, a $950 annual saving that was paid back in less than 2 months.
International Partnership for Energy Efficiency Cooperation (IPEEC) - reports
The International Partnership for Energy Efficiency Cooperation (IPEEC) is a high-level international forum that provides global leadership on energy efficiency. It identifies and facilitates government implementation of policies and programs that yield high energy efficiency gains. Level 1 audit - Tint A Car
After an energy assessor audited Tint A Car’s showroom, workshop area and staff room, the changes made by the business immediately led to a 20% drop in energy use (despite higher temperatures than the previous year). This was achieved by replacing an energy hungry staff fridge, updating desktop computers with laptops, installing a roof top solar system and changing staff practices.
Level 2 audit - Cairns Hardware
A Level 2 energy audit at Cairns Hardware found tens of thousands of dollars in potential annual energy savings. $5500 a year would be saved simply by changing to a more appropriate energy tariff;.$12,000 a year could be saved by replacing lighting on the company’s 3 sites with light emitting diodes (LEDs). Even air conditioning bills could be reduced, either via stronger air-curtains or automatic doors (a potential saving of $11,500 per annum). The company acted quickly, and has already begun making savings.
Level 2 audit - Casey's IGA
At Casey’s IGA in far north Queensland, an energy assessor found the local supermarket could save $3750 per year by switching fluorescent tube lighting to light emitting diodes (LEDs). The business could also reduce costs in the supermarket’s deli display section, if more energy efficient lighting was used, or the display was ‘de-lamps’ by cutting back on lights. These and other measures could save the business thousands of dollars.
Level 2 audit - Clarendon on Spence
A Level 2 energy audit at this luxury residential apartment building found thousands of dollars in potential energy savings. A change in energy tariff would reduce power costs, switching to light emitting diodes (LEDs) would save $1247 a year, and putting a timer on a heavy duty exhaust fan in the car park would cut it’s $3000 power costs. Acting on the recommendations quickly saved the body corporate 10% of its energy spend, despite electricity price hikes and significant savings will be reflected over time.
Level 2 audit - Joe Vella Insurance Brokers
The 30 staff of Joe Vella Insurance Brokers (JVIB) work out of a refurbished historic building in Cairns CBD. The assessor analysed tariffs and advised on how to stay on the current, cheaper tariff – including via installation of a solar PV system, and recommended numerous simple changes to reduce the building’s heat load and save money. JVIB immediately took action and the savings are expected to be imminent, given many of the implemented changes have a short payback time.
Level 2 audit - Union Jack Hotel
The Union Jack Hotel has power bills of around $13,000 to $15,000 per month. After the results of two energy assessments were in, the business knew it would save over $3000 by switching to light emitting diodes (LEDs) lights, and more by installing a key card system for guests (to ensure lights and air conditioning turn off when guests are out). Further air conditioning savings (30%) were possible by upgrading to a more efficient system. These and other changes immediately save the business slash its electricity spend by 14%.
Liddell Taskforce - Terms of Reference, report, statement and response
In 2015, AGL announced it would close Liddell Power Station in 2022. AGL later extended this to April 2023. This would make Liddell the next in a series of coal power station closures. In the past 10 years closures have removed over 5000MW of capacity from the National Electricity Market (NEM).
The Australian Energy Market Operator warned there would be a higher risk of blackouts in NSW after Liddell closes, without more investment in dispatchable power. As a result of these concerns the Australian Government set up the Liddell Taskforce in August 2019.
Lighting and appliance upgrades saves energy and dollars - Glebe Point YHA
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.
