When my wife and I were looking for a home, our main priority was actually that it's "climate proof".
We found a souterrain apartment facing east, on top of a hill, far from any rivers or forest.
So it stays cool in the summer even without A/C, and is unlikely to flood or get caught in a forest fire.

What is souterraine?

[-] mech@feddit.org 31 points 3 weeks ago* (last edited 3 weeks ago)

A fancy French word for basement.

Actually a floor that's halfway between street level and basement.
So it's possible to build normal windows into it, but they're very low to (or slightly below) the ground outside.

The only issue you can have is high humidity/mold due to the high temperature difference in summer but that can usually be adressed with proper ventilation at night.

[-] synapse1278@lemmy.world 7 points 3 weeks ago

A fancy French word for basement. It's just a regular french word.

Cul-de-basse-fausse, that would be a fancy french word !

[-] ZkhqrD5o@lemmy.world 8 points 3 weeks ago

I have a dislike souterrain flats, because while they keep cool in summer, in winter it's a heatsink radiating away all the heat you pay for, even with modern insulation. At least my experience.

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

[-] Valmond@lemmy.dbzer0.com 22 points 3 weeks ago

We do nr 2 (we have a store for nr 1 + sort of blinders), we got the temp at only 28-29°C.

Outside:

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

[-] HerbalGamer@sh.itjust.works 10 points 3 weeks ago

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.

[-] rain_enjoyer@sopuli.xyz 7 points 3 weeks ago

For 1 these metallized emergency blankets work much better. Aluminum foil also works but it's not as durable when put outside

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

[-] arrow74@lemmy.zip 14 points 3 weeks ago

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

[-] bridgeburner@lemmy.world 6 points 3 weeks ago

You need a fan to blow the cold outside air into ur apartment

Every summer, Europeans literally migrate to the hottest parts of Europe. Greece, Spain, Italy, you name it.

Do not underestimate us.

[-] Jiral@lemmy.world 6 points 3 weeks ago

I am going to fly to Finland ;)

[-] MyRobotShitsBolts@lemmy.world 6 points 3 weeks ago

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.

[-] Markus29@lemmy.today 13 points 3 weeks ago

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.

[-] SethTaylor@lemmy.world 6 points 3 weeks ago* (last edited 3 weeks ago)

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

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)

[-] Jyrdano@lemmy.world 9 points 3 weeks ago

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.

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.

[-] dsilverz@catodon.rocks 47 points 3 weeks ago

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.

[-] mtpender@piefed.social 23 points 3 weeks ago

Good point, I suppose the Aussie solution works best in a hot and DRY climate.

[-] davetortoise@reddthat.com 25 points 3 weeks ago

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

[-] tempest@lemmy.ca 18 points 3 weeks ago

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.

[-] FishFace@piefed.social 17 points 3 weeks ago

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.

[-] warm@kbin.earth 18 points 3 weeks ago

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.

[-] FishFace@piefed.social 6 points 3 weeks ago

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.

[-] warm@kbin.earth 13 points 3 weeks ago

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.

[-] FishFace@piefed.social 7 points 3 weeks ago

Let's take everything you said as true.

You're still worse off if you have a poorly insulated house.

[-] Thorry@feddit.org 12 points 3 weeks ago

This is simply not true. Many Europeans have windows specifically designed to let infrared radiation in, but block it on the way out. So as soon as any sun hits any window, that's a lot of heat coming in and not going out. Very nice when it's cold, but not as good when it's hot. Most people have blinds and curtains on the inside, which doesn't help. I have blinds on the south side which are closed, but the rest of the house only has blinds on the inside. So for a lot of hours in the day heat does get in.

Meanwhile I'm living in the basement of a couple who thinks an appropriate temperature is like 65f freezing my nuts off all summer.

[-] heythatsprettygood@feddit.uk 20 points 3 weeks ago* (last edited 3 weeks ago)

~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

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

Funny, I have air conditioning, but my crazy parents say it's bad for you.

Guess I'll just forget about sleep.

[-] kuerbiskernoel@feddit.org 7 points 3 weeks ago

I don't but my house is isolated. Windows open in the night, closed during daytime. Works perfectly.

[-] Nalivai@lemmy.world 8 points 3 weeks ago

The problem now, is that it's hot at nights. You open windows at night, and let 29 degree air in, and there is nothing to cool it down.

[-] Jiral@lemmy.world 5 points 3 weeks ago

It really depends where you are and also if you are in a dense city or on the countryside. Climate Change has made an impact on that as well.
