This AC temperature could save you billions in Heathmont

Air conditioning is costing us more than $1.3 billion a year. But if you switch to this temperature you could save heaps of money.

The battle over the humble thermostat in Heathmont has been tearing friendships apart since air conditioning was invented.

The perfect temperature is a constant source of frustration for Australians in Heathmont. Often wishing they had brought scarves and gloves on menial trips to offices, cinemas and shopping centres across the nation.

Our obsession with making air conditioning is not surprising. Given large swathes of the country have been baking in oppressive heatwaves in recent weeks.

But, our bad habits with this life-changing technology are damaging for the environment and costing us money. To the tune of more than $1.3 billion over the summer months, according to new research from comparison website

“The typical split cycle air conditioning unit consumes around 5.0 kW and costs around 2.7 cents to run per minute,” said Angus Kidman, energy expert at

“This might not sound like much but a full night’s sleep with the air con running can cost close to $13.”

The research shows Aussies waste an average of 4.1 hours per day in energy by leaving their air conditioning running. This works out to cost up to $1.3 billion in wasted energy expenditure over summer while these homes are empty.

More than 2.3 million households will waste power in Australia by keeping their ac running when not home. Which adds an average of $578 to their quarterly bill.

Mr Kidman says that cutting down air conditioning use by just half an hour can save households up to $72 over the three months.


If you really can’t turn the ac off then you should at least adjust the settings. 25C in summer and 19C in winter, argues Tony Crabb, national head of research at real estate services firm Savills Australia.

He said thermostats across the world are often fixed at 22 degrees. Which, he argues, is costing the economy billions and pumping hundreds of thousands of tonnes of unnecessary carbon into the atmosphere. Read here.

If we all stuck to the 19C and 25C rule, Australian businesses could save $100 million and 300,000 tonnes of carbon every year.

“The built environment is heated and cooled to a fixed 22 degrees regardless of the temperature outside,” he said during a TEDx presentation.

“It turns out, that’s the thermal comfort level of a 44-year-old man. It was decided by the Americans in the 1950s, and it’s been that way ever since.”

“While human beings adapt to heat or cold by wearing more or less clothes, we don’t ask our buildings to adapt.

“The [22-degree setting] is so embedded in the psyche of the world that it’s legally written into leases,” he said.

“But why? The thermal comfort level of a human being depends on whether they’re male or female. What age they are. Whether they’re tall, short, fat or skinny. There isn’t one-size-fits-all”.
