Don't do the AC thing, it is a stupid trope under blogfluencers. There are no restrictions (besides positioning the outer unit in such a way that you cause your neighbors to lose sleep). As the summers get more extreme in Europe, more residents decide getting one is starting to pay off, so you see more AC's, but many people think they are doing fine without.

Yeah, never heard of such a thing. The restrictions are placing the units in common areas of the buildings -- in that case you need permission -- and external walls are usually common parts. Placing them in the façade may have additional restrictions.

But, if anything, energy efficiency standards for new construction are so strict that heat is becoming less of a problem.

I can easily google restrictions and share them, and I have in other comments but let me throw it back at you.

Why do 90% of Americans have AC while only 20% of Europeans do?

Why does US have ~4 heat related deaths per million while Europe has ~235 per million?

Do you think it's just stupidity (Europeans don't know the relationship between heat and AC)? Or poverty? Any other explanation?

Maybe because the majority of Europe is closer to Canada, latitude-wise, than to Phoenix, AZ, and there is simply less demand? Less wealth is certainly a factor, too, especially considering how the warmest nations in Europe all tend to be weaker economically.

Maybe its just the higher life expectancy increasing susceptibility? Everyone has to die of something at some point.

Ah yes, heat death, essentially "natural causes". Never mind what's obviously in front of your face.

It is a statistic, 'treacherous' is a word often lurking around the corner.

No healthy person all of a sudden dies from heat, I am sorry to tell. If that would be the case, everyone would be as panicked as you are. Europe has comparatively older demographics. Heat risk mainly affects infants and the elderly.

Most EU countries have free health care, so even people not caring enough for themselves will have a comparatively higher chance to survive into an old age. But also those who didn't die because of a bad lifestyle are part of this demographic. Like I said, treacherous, because you should look at this demographic and start to ask how many hours of life expectancy is lost. Healthcare keeps finding that the elder people just don't drink enough during these warm days.

I guess that if you want to win back these hours, you have to convince those elderly people to install AC or get them to drink enough during hot days. At this age people have a certain flexibility of mind, complicated by the fact that heat waves these days are really more severe than in their lived past.

Let me assure you: if people think it is too hot for them at home and they don't see an alternative, they will install AC. It is affordable enough. But there might be a cultural difference, people don't think of AC as the first line of defense against the hot days. Environmental awareness is higher; AC's contribute to global warming. Anecdotally, looking around I see there is a preference for sun protection over AC's.

Because Rome is further north than New York and Paris is just south of Ottawa/Montreal.

Raw latitude hardly tells the entire story.

Most of Europe simply doesn't need an AC. Spain, south of Italy, south of France, parts of the Balkans. But in countries like UK, the Nordics, Germany, etc. you'd need something more than "open windows" for mere days of the year, if that. The people who live in the places that need AC usually have AC. It's actually pretty damn simple.

Got it, it's cooler, no one needs AC. Next question, why are there a lot more heat deaths per capita. I mean, a lot more (4/million vs 235/million)

Should be simple

Could be lot of reason. Older European cities with high-density stone buildings and less green space often trap heat more effectively than typical U.S. suburban layouts. Europe has a larger proportion of elderly residents (aged 80+), who are the most susceptible to heat stress. You just picked a data and are trying to fit your narrative on top of it without really considering all possible aspects.

> Older European cities with high-density stone buildings and less green space often trap heat more effectively than typical U.S. suburban layouts.

Doesn't that mean that they would need AC, then? At least for those specific buildings.

However, as a European living in Paris, one of the densest cities in the world, I only feel the need for AC like 2-3 weeks a year. I think the issue is that most people dying of heath are already very old and much more sensitive to it.

But if you live in any kind of share building, you can't just go and set up a split. If it is outside the building, you need permits, both from the architects, so that you don't deface your ugly concrete building, and from your fellow residents, who usually vote "no" by default.

You make a lot of great points. You know what would be great for helping those elderly residence prone to heat strokes living in high-density stone buildings with less green space? Air conditioners! In face, I think EU should mandate air conditioners in every home.

Because 'global warming has accelerated significantly'?

then it wouldnt be cooler would it
