What are your advices to cool homes without AC ?
-
Hi there, time to share ways to keep your home cool during hot times
So ok, usual ways I use:
- open everything during night
- close everything during day
- external sheets on windows without shutters
- some curtains to prevent heat from going upstairs
I was also wondering if plants could also help inside, any ideas ?

Something I haven’t seen mentioned is an attic fan. They’re mounted on the ceiling of your highest floor. These used to be common before AC became so widespread. Basically, you open your windows, and the fan sucks air in through the windows, through the house and up into the attic, where an exhaust fan can push it out.

Fans! push and pull air according to wind direction

Lose weight. I'm totally serious. Thin people have much higher natural tolerance for heat.
It's no coincidence that so many developed countries have become addicted to AC. The fact is that most people there are now overweight and in many (USA most obviously) over 40% are literally obese. Conversely, AC is much less common in places like France and Japan, and it's not just because they're too cheap.
If you want to stay cool in a heatwave, it helps not to be wearing a blubber overcoat that you can't remove.

as someone from a similar place, mosquitoes make opening windows at night a health hazard, unless you install netting.
I should be getting to do that...
Yeah the mozzy mesh is a life saver, for both mosquitoes and flying termite/ant swarm after rain, but do keep in mind that meshes will restrict some air flow. Still, it's better than nothing, and combine with that rooftop onion you might get better result.

Look at old hot climates.
notice the afternoon siesta. Sleep in the shade in the hot of the day and work (play) later into the night.
notice large covered porches around the house. Spend more time outside in the breeze and shade.
notice the large windows and doors. When you are inside get plenty of ventilation-
notice the ceiling fan (often slave pulled). Be glad we now have electric fans.
notice the folding hand fans. Portable fans exist, though most of the time the hand fan is better - get one.

As a northern Canadian, I kinda chuckle at the need for an air conditioner. Of course, my punishment in winter.

I assure you that practically every household in Japan has an air conditioner these days. Maybe not some decades ago but things have changed, including the climate. And companies are legally required to keep offices at no higher than 28°C, too.

Offices in all countries have AC, the question is about homes. I doubt "practically every household" in Hokkaido has AC. Here in northern Europe, very few do.

If you live in a humid area, AC will become more and more valuable. Wet bulb temperature. At some point your sweat will no longer evaporate and you'll die. Climate change cometh.
Thanks, I went down a rabbit hole reading about wet bulb temperature.

wrote on last edited by [email protected]Every home I have visited in Japan over the past two decades has had A/C units. You may be right that in regions where it is very cold an A/C unit may not be necessary. However, as heat pumps are one of if not the most energy efficient ways to not only cool but also heat a home, I wouldn't be surprised to find them even in colder regions.
Add on the fact that houses in Japan are generally considered a depreciating asset, so until recently demolitions and new construction were favored over renovations, I stand by my first statement.
Additionally, every place I have ever rented has come with at least one A/C unit, and additional holes are predrilled in other rooms so that split systems can be installed.

I put foil insulation on some of my bigger windows in the summer. Especially southern facing windows (in northern hemisphere). That mixed with tons of fans and the occasional cold towel when needed helps tremendously.

Basically, you open your windows, and the fan sucks air in through the windows, through the house and up into the attic, where an exhaust fan can push it out.
Second this but wanted to add that a remotely mounted fan (one that's connected to the intake vent through a duct rather than being mounted directly in the ceiling) significantly improves the experience because it cuts down on the noise and minimizes heat losses in winter.
We have a gable mounted attic fan that draws air through the house. 5000 cfm makes for a nice breeze.

Fair enough. Most of Japan is hotter in summer than northern Europe. Here it has been 35C for much of the last week and domestic AC penetration remains extremely low. There are also quite few fat people, and the two things are probably at least a little bit connected.

I don't disagree that people who are overweight will feel hotter. The rainy season makes it feel hotter than just the temperature here, too. Buildings here are probably more poorly insulated, too.

Gable-mounted still incurs direct vibration into the structure. I have a QuietCool whole house fan that is suspended in midair from the gables, to reduce that vibration and noise, while being ducted from a framed opening in the hallway ceiling.
Whole house fans are pretty great during the right season, but you need to be aware of the humidity level outside or you can make things worse even if seems cooler at the moment. I also have central AC that gets run either when it’s too humid or too hot at night. But overall I’m very happy with the whole house fan and only having moderate insulation - the house resists heat incursion during the day and then we can quickly cool things down in the evening without using too much electricity.

wrote on last edited by [email protected]How is losing weight going to help right now? They can hardly lose enough weight in time for the next heatwave.
Or maybe they're in the menopause.
Or maybe it's 50C out.
Or maybe they're on one of the plethora of medications that causes heat intolerance.
Or maybe they're elderly.
AC is horrifically expensive (energy bills) and terrible for the environment, by the way. People aren't cheap, they can't afford it.

My office in Southern Germany doesn't have AC, even though it should. It's the hottest part of Germany.

Lüften (airing out)
At night. Not when it's 40C out.

Years ago I was watching Doomsday Preppers and one fella dug a long trench, 100 foot if I'm not mistaken.
In the trench he laid a large PVC pipe and filled in the trench. At the far end of the pipe there was an air inlet. He ran the pipe into his basement and up inside a wall with an inline fan. Cool air, as well as fresh air.
Didn't do anything for the humidity, I suspect.
He claimed it worked, I can not confirm.
It does make since as it's about 4c/39f four feet/1.2m underground.
