I completely agree. Historically AC has not been necessary for the one to two days a year it was needed, but that world is gone now and the situation has changed and the widespread adoption of AC is now necessary.

Its going to be a huge challenge because the buildings are not designed with that in mind, many buildings are hundreds of years old making these sorts of renovations notoriously difficult and expensive, but it has to start because climate change is only going to get worse and worse.



Is it that hard to drill an 8cm hole to run some refrigerant pipes through the wall?


Yes!

Most of Europe has a "registered building" system, where buildings above a certain age are considered historic. Renovating those buildings is an extremely difficult, expensive, and bureaucratic process. You generally need to preserve the period-appropriate look and materials. An AC unit sticking out of a wall won't pass muster.

Even newer buildings are problematic. an acquaintance of mine lives in an upper-middle-class apartment complex that was finished two or three years ago, and their architect has some claim in the contract that prevents residents from installing AC units to "preserve the building's unique look."

The US is build around privately-owned housing (and hence creature comforts) a lot more than we are, so AC is a lot easier to implement there.


>Most of Europe has a "registered building" system, where buildings above a certain age are considered historic.

It feels weird to have to mention this, but although there are a lot of historical buildings in Europe, it's not the norm.

Population grows. There was a noteworthy war not that long ago. The vast majority of buildings are not that old.


There was a good book recently that described Europe as an open air museum. I honestly don’t know why you all put up with that nonsense. Is your country for the living, or the dead?


History nuts in Europe are like the gun nuts in the US (and the hunters / farmers in both). Their antics are often destructive to the rest of society, there aren't that many of them, but they're loud and influential.

And just to be clear, there is a huge difference between a person who has a keen interest in history (nothing wrong with that), and one that wants to leave every single old building untouched, and if there's a danger to residents, move the residents.


If you rent the place and your landlord doesn’t want it you’re out of luck. If you own the place and your neighbors don’t like the noise of your AC you’re out of luck too. If your building is one of the many buildings protected for historic reasons only God can help you.


Sure, in which case, you can do what many New Yorkers who rent do - put in a window unit.


European windows don't slide like American ones. They tend to open down the side or at the top, window AC doesn't work. It just leaves Portable AC and people do buy them but they also don't work very well.


That's not the only thing required to properly install an ac unit. Do you genuinely believe people die rather that drill a hole? Lile that's the blocker? What a weird take


I’ve installed them myself, there’s not a whole lot more to it. Even easier if you have double hung windows to mount one on, though my understanding is that they’re not that common in Europe.


Not a whole lot more? Mounting a 40kg external unit on the facade of a building on the 5th floor is nothing to you? And that's after you get a permit to install it on the facade, which you will likely not (depending on the country).

If you have a balcony, you can mount the external unit there, but then you need to route the piping to the room(s) that need AC. Then you need to cover the pipes somehow, which is still perfectly doable, but goes way way beyond "drilling a hole".

You can have a portable unit, but it's loud, takes up space indoors and needs to be stored somewhere most of the year when it's actually cold rather than super hot.


Certainly not getting it done with that attitude. I’m in China at the moment, none of this stops the Chinese, their highrises are festooned with the things.

It’s ~25kg for a 2.5kw/9000 btu condenser I just looked at, but yeah, if there’s no balcony/fire escape, and you’re well off the ground, you might need some rappelling gear, and you might want a pro. No idea about whatever heavy bureaucracy you live under, that’s a human imposed rather than fundamental challenge. Pipe routing isn’t a big deal, the copper lines are very flexible, just need to be careful not to kink them - give the bends a good radius. And to answer your unstated objections, you will need some tools you almost certainly don’t have lying around. Mostly, though, you need an attitude of being able to do stuff, and getting it done.

Or you can get a portable or window unit. Midea makes some really nice window units now. Might need hung windows, though, not sure whether it’s possible to make them work with casement windows. It takes a little space, but that doesn’t seem like a huge deal?

Or do nothing and just deal with it.


You went from "just drill an 8cm hole" to "rappelling gear, heavy bureaucracy, pipe routing etc". I don't think there's more to say here.


So you are saying temperature has risen enough to warrant an AC now? Due to climate change? I thought climate change was on aggregate ~1C difference but my data is a decade old the last time i looked into it


The average temperature across the entire globe averaged over a year does not mean that each day is subject to the exact average added to it.

Global warming intensifies differences in weather patterns. Hotter hots, colder colds, more intense storms, etc.


Seeing as it's so commonly misunderstood I wonder if "catastrophic climate variance" wouldn't have been a better term in hindsight.


People don't know what variance is.

Most people have an intuitive understanding of what an average is, but "distance from the average" is mystifying to them.


And if you're trying to sell the public on the numbers of what's concerning, those numbers should be able to communicate the changes they expect.

"This number is small but it means BAD THINGS" isn't a very good message


Ok fine I hear you, in that case how about catastrophic climate chaos? It's even alliterative.


I'm not sure a more complicated term would prevent people who don't want to understand the issue from finding new ways to not understand it.


Pretty easy to look this stuff up rather than depend on decade old memory. Temperature in Europe is rising much faster than the worldwide average. Here it says +2.3C by 2022 - that is significant.

The relevant data is number of days per year with temperature above X degrees. That number has risen quite a bit over the last decades.
