We don't have to have double glazed windows in Australia. The energy rating is often sold as 5 star! But, the scale is out of 10 🙄.
We're a dumb country when it comes to building houses. I'm not an architect, or an engineer, but, out summers reach 40°C+ in summer, yet our modern houses have dark grey roof's made of colorbond steel. Too hot outside, let me crank my air con...there goes that 5 star rating of my barely energy efficient home
The star system for housing here is somewhat lacking. Input from vested interests from within industry has made it less than ideal from the consumer point of view. Although its not utterly useless like food star ratings.
We really should be looking to certified passive houses as the aspirational standard.
I work for a global company headquartered in Europe, and we regularly have visitors from the mothership come to Sydney. Every year, without fail, they will all regularly comment on how they've never been so cold indoors. They also come from countries where it snows regularly.
Yup. We’re living with the mistakes of the past and no one wants to fix it for the future.
Fucking moronic people who looked at the Queenslander and thought, “that’s PERFECT for a giant paddock of a Territory that regularly drops below freezing!”
And then 80 years of builders followed suit, but each iteration they stripped more of the charm out.
If you are poor and live in a shit house, get one of those wearable blanket things (preferably a thicker, more expensive one) and some ugg boots (again, the best quality you can afford). You won't need heating with this combination.
I have an OG one too - wearing it right now, in fact! You can get them very cheap now at Kmart and the like but they definitely feel a lot thinner than the original. They're not always as long, either.
could the issue be that homes are built with lighter materials?
I'm from Europe, and we get really cold winters. My apartment never drops below 17°C even without heating on. Even individual homes, I know are insulated so it never is too cold.
If I could afford to, my house would be colder than 18 C or 64.5 F. I have my thermostat set at 68 and is still hot AF in my bedroom and living room.
Edit: I live in a place where the absolute lowest the temperature gets is 18-25 C, I used to live where the lowest it got was -51 C. Not everyone is acclimatized to that kind of cold, but I like it, especially when I’m sleeping.
Edit 2: my most controversial comment is expressing my opinion to a bunch of freezing Aussies that I prefer to be cold. Make sure you waste more of your effort downvoting me, and less effort figuring out how to use space heaters, put plastic up on the outside and inside of your windows, and hang up blankets to keep warmth in your critical areas. Y’all wouldn’t have survived a Minnesota winter. Just be grateful they didn’t sentence your ancestors to exile in Canada I guess 🤷♂️
Then you would be warmer than most homes here. On average the homes they studied were over 18 degrees (64.4 F) for less than 5 hours a day (or closer to 2 hours in Tasmania) and dropped down to minimums of 7.4 (45 F).
Several places get pretty cold. I wouldn't say it's a European cold, but most people here assume it'll be a decent temperature so when it drops you really notice it
Hey I'm Aussie and with you, I like what we call cold in Brisbane, middle of winter and I only wear shorts and t shirt, everyone else here is rugged up like it's the Arctic, I would be happy if my place sat at 18 all day!
Bubble wrap is a good insulator! Spray water and it sticks to the window!
Now, I've just done an experiment with bubble wrap. I had 2 rooms basically facing the same way that got morning sun from about 7am to noon, and measured temperature differences between them.
It does help with reducing temperature movement. That's on the way up as well as on the way down. From 10am to 5pm it's colder in the insulated room as it doesn't heat up as fast. Then from 6pm to 10am the insulated room is warmer, as it doesn't cool down as fast. The difference wasn't huge; only about 1C max.
This was without any active heating/cooling. I suspect insulating would be a much better advantage if you were pumping warm/cool air into the room and maintaining it.
External temperature ranges over a 3 day period were from a 17.8C max to a 5C min. Wider/faster temperature fluctuations would also see a benefit to insulation. The biggest difference (advantage bubble wrap!) was on the coldest day when external temperatures were always below the internal temperatures. It stayed warmer than the non insulated room.
I'll give it a go in summer to see what will happen as well....
From quick research the answer seems to vary depending on region but over 32 is considered hazardous to health for prolonged periods, for healthy adults
