A recent temperature dip has Australians taking to social media asking an important question: why are our houses so cold? or signup to continue reading Sydney and Melbourne experienced their chilliest morning of the year on Wednesday, with lows of 6.5C and 1.4C respectively.
Days earlier Central Queensland had its iciest night on record at 5.6C, with residents waking up to unseasonable frost covering the ground. Since then, multiple videos have gone viral on social media of people complaining that Australian houses are ill-equipped for the weather.
"I can confidently tell you that the coldest I have ever been is living in a Melbourne share house in the middle of July," one user said in a video on social media platform TikTok. Most homes in Australia are poorly insulated with inefficient heaters that can be expensive to run, RMIT senior lecturer Nicola Willand told AAP. "If you don't have that, heat just dissipates out, so even though you may be heating (the room), you don't really feel the room warming up," Dr Willand said.
That was especially so for homes built before the Nationwide House Energy Rating Scheme was introduced in 2004, she said. While new homes are required to reach an energy rating of seven out of 10, such properties are often too large to keep warm. Many Australians assume their homes are supposed to be cold in winter, while social media videos about the cold are often posted by migrants from countries with colder climates.
The chill is not only uncomfortable.
