Australian Government

Lighting can consume up to 40% of energy in commercial premises, depending on the nature of the business and type of lighting used. Street and public lighting is the single largest source of carbon emissions for local governments.


Heating and Cooling Depending on the climate zone, heating and/or cooling can account for 20% to 50% of energy used in Australian homes. Choose the most energy-efficient appliances or system that best suits your needs. To maximise energy savings and personal comfort, seal draughts around doors and windows with weather strips. Roof and wall insulation, as well as good curtains, can significantly reduce cooling and heating load.



The Australian home has a big problem: it's draughty, poorly insulated and costs a fortune to heat and cool. Most older homes have an abysmal energy efficiency rating – and we are paying the price. So what can be done to fix the problem? A lot, actually. And the government could play a role in retrofitting Australia's existing housing stock with its coronavirus stimulus spending. Here's how. 

ABC Education

Discover how housing design is changing and what it may be like in the future. Energy efficiency has become increasingly important in sustainable housing design. Innovative solutions to reduce the use of resources are the way of the future. Can you imagine living in a parasite house?


In this episode, we introduce students to the concept of efficiency, which is a measure of how much useful energy you get out of something compared to the amount of energy that you put into it. We answer a bunch of questions including: How much light energy we get out of light globes compared to the amount of electrical energy that goes into them (Hint: it’s not much; they should be called heat globes!), how much kinetic energy we get out of cars compared to the amount of chemical energy that we put into them (Hint: it’s a bit more, but not that much more!), and how our arched feet make us the long-distance running champions of the animal world. This video is the most energy-efficient way of learning everything that you need to know about energy efficiency!

Some years ago retired engineer Manfred Pruter and his wife Nita moved from Melbourne to a rural property in Central Victoria. By using solar, wind and numerous water tanks the couple have created their own alternative energy paradise. The Pruters supply 100% of their own electricity, heating and water. They now live independently of the energy and water authorities. This inspiring programme is a must for anyone interested in renewable energy and sustainability. Learn about the principles of solar, wind and thermal heating and the potential they have to shift society away from fossil fuels.

Your Home

Housing of the future will be judged by very different standards to the housing of today. As a starting point, it will need to respect ecological limits and suit significantly changed demographic patterns and lifestyles. These principles are embedded in the concept of ‘positive development’ — development that has a net positive ecological and social impact.

Sustainable Schools

Rating tools are a fast and easy way for the community to see how efficient their buildings are. NSW Primary and High schools can use the Schools Energy Stars tool to rate their energy efficiency and set reduction targets to reach higher levels of energy efficiency.

Build a house with maximum energy efficiency by adjusting the design to suit the local climate.
Redesign the house to maximise the financial return of design features. Investigate initial costs and cost savings over a long period

Vertical Garden- Patrick Blanc

One Central Park is a mixed-use dual high-rise building located in the Sydney suburb of Chippendale in New South Wales, Australia.[1] Developed as a joint venture between Frasers Property and Sekisui House, it was constructed as the first stage of the Central Park urban renewal project

The story behind One Central Park

Energy Matters

Most of the energy we use in Australia comes from electricity, wood and natural gas. Electricity represents 50% of energy used in Australian households. This is  large component of the household budget, and for the sake of cost alone, people are focusing more on energy efficiency.
