For anyone looking for some cheap help tips:
-
Block the sun from comming in, by hanging a curtain or bed sheets on the outside of the window. Of course real shutters would be even better, but price and time wise this gets you there.
-
Close your windows in the morning BEFORE 8:30 or so. Open then after 20:00 BUT ONLY iit’s colder outside. Keep them open during the night. You can not cool a house down with warm air. Yes it’s warm inside, but it’s even hotter outside so opening a window during the day does not help you. If you like a breeze, buy a fan
We do nr 2 (we have a store for nr 1 + sort of blinders), we got the temp at only 28-29°C.
Outside:
Holy fucksticks, 47… Good luck out there
That’s the thing I can’t get my german roommates to understand they keep opening the windows in common areas when it’s the peak heat of the day.
Sorry guys lüften can’t fix everything
I’m in the attic so all heat goes to my room; I need to keep the shades down 95% but leave the window open so the heat can escape and air can circulate.
For 1 these metallized emergency blankets work much better. Aluminum foil also works but it’s not as durable when put outside
Yes, this exactly! This works especially well if you have temperature sensors in your house, since then you can know when exactly to open and close based on the difference between internal and external temperatures (or at least that’s what I say to myself to justify my Home Assistant setup). Extra effective if you put a fan in the window during the cooler night.
Sensor? Home Assistant? Howmuch is good enough…
BTW just in case, I think it was TechnologyConnections who did a video of a fan. But the air from a fan creates friction with more air, and you can get way more out of a fan when it’s surrounded by more air (so don’t stuff it in a carton window hole)

Tonight it cooled down to 19°C where I live. I opened all windows at about 10pm, when the room thermometer measured 31°C in the living room.
When I woke up at 7 it was still 26°C inside.
This is bullshit
If your place is designed to retain heat that’s all their is to it.
My place in Germany it was much cooler on hotter days earlier in the heatwave. Today is the coolest day of the heatwave so far, but the building has heated up too much over the previous days. So now it stays hot. By the end of the week I expect this room to be an oven
I’m tempted to make a joke about a german and an oven room but I won’t.
I heard it anyway.
You just did.
You need a fan to blow the cold outside air into ur apartment
Or blow the hot air out of the house. Or even better, both. One fan in opposite Windows creating a steam.
It’s inside the walls. The heat is inside the walls. The waves. The walls. The waves are in the walls. Inside our walls.
Blow air out during the day, so cooler air in corridors get in to the apartment. Blow air in during the night, so cooler air outside get in to the apartment
Every summer, Europeans literally migrate to the hottest parts of Europe. Greece, Spain, Italy, you name it.
Do not underestimate us.
I am going to fly to Finland ;)
Good luck. I went there last July during a heat wave and it was 38 most days. They’re absolutely not equipped to handle that. My hosts did what they do when it’s cold and sealed up all the windows and doors. Now I live in a hot climate in the US and it took me days to convince them that you need to open the doors and windows and get air moving. The idea was entirely foreign to them.
We do have better insulation here, especially with modern homes you’re better off closing doors and windows during the day and opening them by night.
I second this. I live in southern Romania. It goes up to 42 in the summer here. 35 or over daily for weeks at a time. My building is built like a tank
It works if you open doors at night to cool the house off but seal it before the sun heats the air up
Humidity is the issue where I live. Gotta close windows and have dark curtains or your house fills up with warm air from outside.
Best place in a flat or appartment building is the cellar, because air never mixed and cool air pools down
Weather forecast currently is 12-18C in a week ;p
That’s 100F in Freedom Units™. In fucking Finland. We’re cooked, soon to be literally.
Holy shit, is this the moment where our balkan mud and straw houses just win? Finally, the punishment of our oppressors that was promised to us at battle of kosovo has come!! (/j ofc)
We have bought reconstructed late 19th century house - all ground floor, with 1m thick stone/brick walls - here in Czechia. Even without air conditioning the temperature inside never gets above 23 degrees C even in the middle of summer. Its great. Bitch to heat though.
get small towel/flannel
soak in water and squeeze out until damp but not dripping
drape over your shoulders close to your neck
this directly cools your carotid and jugular, tricking your brain into thinking it’s colder than it is as well as cooling the rest of your body
Australians:
Protip: Take a shirt and wet it down, then wear it and sit in front of a fan. It works like an air cooler. The evaporation draws the heat out of your body and the fan turbo-charges this process.
As a Brazilian who’s also experienced with a hot climate, I’d say this would work if anthropogenic climate change weren’t leading to… wet bulb… high temperatures. When current temperatures are 40°C and the air’s relative humidity is practically 100%, no amount of wetting or sweating will get rid of the warmth, because evaporation can’t happen when the air is already saturated.
Good point, I suppose the Aussie solution works best in a hot and DRY climate.
Meanwhile I’m living in the basement of a couple who thinks an appropriate temperature is like 65f freezing my nuts off all summer.
~18 degrees Celsius
When can I move in? /s
but seriously that’s my ideal temperature year round, much to the chagrin of anyone else when I get a hotel room with AC
We got Mr blanket-for-skin over here
I’m wearing a hoodie all the time and hearing “aren’t you hot?” every time I walk through the house. No… That would be why I’m wearing a hoodie even though it’s 85 outside…
I feel like I’ve seen this headline every year for half a decade.
Time to put those heat pumps to use, we are not doing anything about climate change so it’s the new normal.
I had ordered an airco before this madness started, but unfortunately the had to order it and it hasn’t arrived yet. It has been hot for days already, it’ll be 35 or higher the next 4 days, and I live under an almost flat, black roof with the sun on my the entire day. There will be no eepy sleepy time
Welcome to Canada 2021, where I thought the forecast was a typo
I was looking at weather reports that year for like, northern Quebec, to see if maybe I could move there for the summer and hopefully not get eaten by black flies.
However so far it’s been pretty temperate here this year.
Houses that trap heat also trap cool air.
People who say their well-insulated house “traps heat” are probably keeping their windows open in the hottest part of the day.
Even with all the windows and blinds closed, the temperature of the house still gets warm. Then it’s hard to expel that heat before the next day, so it gets even warmer.
A poorly insulated house would heat up quicker, and so have a higher peak indoor temperature. They will lose heat faster at night, yes, but if you ran a comparison with each house starting at the same temperature and allowing them both to equalise at the end, the average temperature of both would be the same.
The key insight is that insulation makes it slower for the outside temperature to heat the house up as well as to cool it down, so in a heatwave, insulation blunts the worst of it. Also you can actively reduce the insulative properties of a house by opening all the windows, so that it actually cools down much faster at night. This means that, in practice, the average temperature of the well-insulated house will be lower than that of the poorly one.
This kind of conversation (which occurs repeatedly whenever the weather gets hot in the UK) makes me despair, because we all need to be insulating our houses better, both to reduce our energy usage in the winter, and to protect against extreme heat.
The only way you are cooling these houses down at night is if there’s a mighty breeze and cool outdoor temperatures… or if you took the entire roof off.
Your theory might sound good, but in reality it doesnt work that way. Temperatures during this heatwave wont even drop below 20-25c at night, opening the windows doesnt magically mean that the inside drops to match outside as well. It takes hours and hours to do so, and by then the sun is back up, heating the houses up again.
Let’s take everything you said as true.
You’re still worse off if you have a poorly insulated house.
Running a dehumidifier can also help lower the temperature. Water takes a much longer time to heat up/cool down than air does. If you remove the warm moisture from the air and then open the windows and let the cooler 20-25 degree air inside, it should cool the house faster.
That’s not true. I keep my shutters drawn and window shut in my room, and it’s still getting hotter and hotter.
The first couple of days my walls were still cool to the touch. They radiated cool. Now they are warm. They are actively absorbing heat faster than they can be cooled in the evening
“The situation is bad, therefore this makes no difference”
Am I reading this right?
No, but that’s okay you’ve picked your hill
At my place that trick works the first day, but after that it’s over. The house always heats the same under this sunshine, slowly rising to 28-30 at the end of the day with everything closed and down from like 22-24 in the morning. The only question is whether that’s better than a higher temperature with a slight breeze and fresh air. Today, it won’t be higher than 30, so I’d rather have wind. The next 4 days, it’ll be 35 or higher, so everything will get closed down during the day
I’d keep things battened down so you’re starting from a lower base.
A breeze can be provided by a fan. (And it makes a huge difference - bigger than the breeze through a window)
Cold places usually have giant windows to let more sunlight in. You can definitely optimize for heating or cooling efficiency
i do use the AC a lot u know >:|
Funny, I have air conditioning, but my crazy parents say it’s bad for you.
Guess I’ll just forget about sleep.
It is, but then so is heat stroke
Europe is headed for an ice age, so just hang on.
33c in sweden where i live which is a very nice temp but the people melting arround me. Also where i used to live in hungary will have 41c which is somehow almost a record but it never goes above that. I dont understand how the weather works there, last summer we had like ten days with 40+ but the all time record for all of hungary is sonehow only 41.9 at the same time even tho there are hotter cities than where i lived. Kinda shit to have almost record breaking weather every year cause youre like “ahh but serbia and bosnia have it worse” but in actuality its almost always hotter in hungary. My guess would be that hungary always has been very continental and that the recent heatwaves mainly come from some sweeping effect in europe which the carpatgians and alps block for hungary?
