Up vs down, always. Not surprising in the least.
rappatic•1h ago
> Due to extreme weather conditions, forced shut down of air cooling system from floor 1 to 7 for the rest of the day

It's like satire. What is AC for if not extreme heat?

gambiting•56m ago
Normal day to day cooling, I mean, obviously? Like if you have a system designed to operate in 25-30C(normal summer in most of Europe) but then you have a spike of temperatures going to 40C for a few days in a row, it shouldn't really be a surprise the system doesn't work in conditions it wasn't designed for? The compressor overheats and shuts down, especially if it wasn't installed in the shade.

Just like heat pumps for heating in winter are amazing for our regular mild-ish winters, but if you get a really cold spell and it drops to -35C, it's just not going to work at all to a point where it might not even start - you could also say "well what's the point of a heating system that can't heat in extreme cold".

The extreme is the keyword.

wongarsu•55m ago
Historically temperatures above 30C (86F) were rare in Europe, so thats what many ACs are sized for. Now they face 40C (104F), and many AC installations can't keep up

Shutting down AC on floors 1 to 7 likely allows them to get better performance on floors 8 to 13

mytailorisrich•32m ago
That's not true. Temperature above 30C are the norm in summer in Southern Europe (which means quite higher in the Sun and in a heat trap location). Now, yes 40C isn't.

But I am unconvinced that AC manufacturers have different "sizing"... An AC unit is for hot places and the outdoor unit may be in a very hot spots with ambient easily above 40C.

wongarsu•21m ago
Brussels is however not in Southern Europe

By sizing I simply mean the number and capacity of roof units. Cooling an office building down by 8C is a lot easier than cooling it by 18C. I doubt half the roof units are shut down. Maybe some are, but most will have their output redirected to cooling the top half of the building

Arnt•10m ago
That building doesn't have the kind of outdoor unit you're thinking of, it has central climate control and gadgetry on the roof. You can see it on Google Maps.

Also 19 satellite antennae, if my count is right.

slillibri•45m ago
When there is not enough AC, people sweat. It’s better for half to sweat to death so the other half can remain frosty.

antonkochubey•45m ago
My multisplit system costs <€60 a month to run even during the hottest months, which is way below heating costs during winter. And that's keeping entire apartment at constant 22ºC - people with higher "comfort temperature" can keep the bill significantly lower.
cbarnes99•1h ago

dranudin•1h ago
The A/C cannot keep up the load, due to the exteme heat. So they decided to just not cool one part of the building, to be able to keep cooling the other part .. It is now interesting who was in which part ;)

And all of those Europeans that had comments about the Texas ERCOT warnings of heavy loads during extreme weather. Although, it's been a while since I've received notices/requests to adjust the use even if they were bump it up a few degrees vs turn it off.

The whole conversation about upper and lower floors is absurd. Obviously the upper floors are absorbing more sunlight and need more cooling.

Ground level and basement floors have been known as the coolest places in skyscrapers for centuries.

phendrenad2•44m ago
Any building with modern (last 100 years) insulation is going to have relatively equal distribution of heat between the floors. Except the bottom floor, where people enter/exit and mix in outside air.
preommr•43m ago
Except it wasn't the basement and first floor.

It was the first seven floors. Coincidentally, also the floors most of the higher-ups don't work on. Or at least that's how it's being reported, so I don't think people's outrage is absurd.

alistairSH•14m ago
4pm on a Friday, people were likely already heading home. This is being blown out of proportion.

The broader discussion about AC in Europe is good to have, but this specific story seems to be borderline click-bait.

Havoc•46m ago
wow that’s an ugly look.

Kinda weird though even for Europe that a high profile 10+ floor commercial building doesn’t have suitable climate control

frollogaston•45m ago
"even with working AC, the temperature inside was still 25.7 degrees."

So 78F. I wonder what temp the lower/non-AC floors are at. It's reasonable if they want to prevent the upper floors from becoming insanely hot, since hot air rises.

lumrn•38m ago
Just adding some context on the AC and the building as well which was explained by journalist David Carretta (who follows EU politics, written in Italian) here https://x.com/davcarretta/status/2071592636260012175.

To summarise, AC was turned off floor by floor, with the switch off starting from 16:00 over a Friday, a time when most administrative personnel is getting off work for the weekend. The entire building had AC switched off by the end of the day, including the upper floors. Note that AC was working fine this Monday.

otikik•33m ago
If the people in the lower decks were allowed to go home, I don't see the issue.

If they were forced to work without air conditioning and it was me, I would go to a doctor, tell them I am suffering from heat exhaustion, and get a voucher for not returning to work until the situation gets fixed.

alistairSH•15m ago
The shutdown began at 4pm on a Friday. So, yes, much of the building was on its way home for the weekend. And the higher floors are mostly allocated to the leadership/commissioners, who are more likely to work after hours.

Now, why can't the building handle running the AC without an emergency shutdown? No clue, seems odd to me, unless there was a neighborhood-wide power issue?

zuzululu•24m ago
What really appalls me is that they have now started to blame Americans for the heatwave that the hot air from AC units are to blame and doubling down on their insistence that AC are harmful to the climate and telling people to not use AC.

I really think that this is the straw that breaks the camel's back moment for EU. Right now people are learning that EU = unbearable heat and other things.

anonzzzies•23m ago
Air conditioning weirdness around the EU: I live in the EU and everyone I know, including not too well off people on benefits and pensions, have aircon. I have multiple houses and dozens of aircons, but many friends in small apartments have them too, mostly since covid. In one house I have them running summer and winter 247 and the electric bill is still below 100E, way lower than people with swimming pools.
kleiba2•19m ago
It depends on the country. If you live in a place that - traditionally - had only an expected few days of really hot temperatures every summer, it wasn't worth the investment. With climate change, the temperatures are now higher and the heat stretches longer.
anonzzzies•14m ago
Agreed, the EU is not that small and Southern countries had to go before northern but now I feel it is pretty normal. Might be my circle of course. Or in a shorter way; YMMV. I know zero people without aircon and one couple live fulltime in a yurt.
cmoski•9m ago
"A third staffer working on the 8th floor told POLITICO on Friday that even with working AC, the temperature inside was still 25.7 degrees."

I set my AC to 26 degrees. Otherwise it feels too cold.

A 12K BTU mini-split system is about 300EUR. How is this unaffordable for most people? Even an 18K unit is about 500-600EUR.
antonkochubey•46m ago
Realistically a decent mini-split that won't break in a year and won't make too much noise starts at ~€600-800 + €400 installation in a low-labor-cost country (Latvia), in high-labor-cost countries such as Germany the installation bit might be twice-thrice as expensive.

wnevets•50m ago

rapsey•38m ago
It's not the money. In many places you need to go through permitting to get it and they do not want to give it to you. Often you also need a signed approval from every person in the building.
mtoner23•28m ago
so yes something is very wrong
wnevets•27m ago
There is something very wrong in the EU if installing a life saving window air conditioner requires a permit or signed approval from every person in the building.
black3r•49m ago
It's not that expensive. There are other reasons why people can't install one in Europe than money. Mostly for people living in apartments. In an apartment building you need the approval of other apartment owners to "modify the building facade". And some people have terrible neighbors. Another thing that happens in Europe is that if the building is 100+ years old, it's facade may be protected as a "historic building" and then you need another approval from some bureaucrats which are responsible for protecting historic buildings. And of course if you're renting, you need to convince your landlord if you want a proper AC not a portable one.
hparadiz•37m ago
People on here will literally write walls of text over the most mundane nonsense.

Get a free standing unit like this: https://i.imgur.com/giewYeK.png

Shove the plastic tube outlet out of a window. End of installation. You're welcome.

Seriously why is this so difficult and what is this learned helplessness? You would rather be miserable than do literally anything?

Markoff•33m ago
you don't need that on balcony, most of the apartments have balcony, stupid excuse, same applies for historical buildings with balcony

If a tree falls in a forest and no one is around to hear it, does it make a sound?

If there is a balcony and you install it there, so nobody can see it from the street, is there an AC installed? I am can you even use your balcony the way you want and place there big cardboard box if you need? Same thing. Facade is a one thing, balcony is something completely different.

graton•46m ago
> Most ordinary working people can't afford the cost of installing a system. Even a portable one.

I just watched a video where a person bought a £200 portable unit. He was using it in the UK and said he spent about £0.89 / day. And I'm assuming they won't use it for that many days a year.

Seems affordable enough for "most ordinary working people"

https://www.youtube.com/watch?v=jOmzVWTH3xo

scrlk•38m ago
As a side note, it's nearly impossible to buy a dual-hose portable AC in the UK and Europe. For whatever reason, the market has converged on inefficient single-hose portable ACs.
Markoff•36m ago
funny take

Bulgaria is one of the poorest EU countries and I have seen there way more ACs than in much richer Czechia or elsewhere, this is not about price at all

heck, even in Czechia I find much more ACs in some poor cities compared to the richest Prague, I've seen bigger AC ratio per apartment in my small poor ~40K hometown than in Prague, in our 40 units building in Prague I was the first one to have AC, after many years now followed by neighbor under me, 2 out of 40 units in relatively rich Prague, crazy (though it's true our top corner of the building is warmest from all apartments)

zzzeek•35m ago
there is significant resistance to air conditioning in Europe at many levels (all of which are invalid or solvable):

* "not technically feasible" - people talk about old buildings with oddly shaped windows

* "can't afford it" - as you see here. people talk about the units themselves and the electricity bills

* "our infrastructure can't handle it" - this has to do with things like grids overheating, failing

* "our infrastructure can't handle <the regulations>" - things like nuclear reactors in France not allowed to raise the temperature of rivers by another N degrees during a heat wave

* "it's bad for global warming" - a little late for that, probably should save lives first

literally hospitals in europe don't have AC throughout the entire building yet. global warming is really coming at them fast

Tarq0n•34m ago
In the past with harmful refrigerants and lack of renewable energy AC simply was not justifiable in most of Europe. Progress on both fronts plus global warming is changing that only recently.
bee_rider•31m ago
On the bright side they’ve probably waited long enough to roll out heat pumps instead of window ACs, right?
quantummagic•28m ago
As far as I know, a heat pump and an AC unit are essentially identical. Although some heat pumps can be reversed, and act as heaters in the winter. But one isn't more efficient than the other, they employ the exact same physical refrigeration cycle.
coryrc•26m ago
I think GP's point is that winter heating can shift to nuclear- and wind-powered instead of mostly burning fossil fuels.
bee_rider•21m ago
Oh, I had them filed in by brain under “more efficient temperature control” but it looks like they don’t have an advantage over ACs when cooling. (Just over typical heaters, when heating). Oops.
wil421•17m ago
That’s true however moving heat in the winter is much better than burning things.

Gas furnaces are 80%-98% efficient, heat pumps are 300-400%.

quantummagic•25m ago
Some of the discussion going online, has asserted that heat related deaths in Europe exceed gun related deaths in the USA by some margin. If true, it has been ignored as a problem for too long.
delecti•7m ago
Yeah, annual heat deaths in Europe (about 70k) exceed annual gun deaths in the US (about 44k) in absolute numbers. They're slightly under US gun deaths if you adjust for population (about 13 per 100k gun deaths in the US, and 12 heat deaths per 100k in Europe).

In comparison, fewer than 2k people die annually of heat in the US, well under 1 per 100k. And for symmetry, there are about 7k gun deaths annually in the EU, which is just slightly under 1 per 100k.

mancerayder•13m ago
Well the Greens in Europe handed Russia leverage thanks to relying on natural gas instead of nuclear, which it opposed (thanks German Greens).

In France these ideologues oppose A/C becauase it's evil: it makes us comfortable when we should be uncomfortable - if we are comfortable in an era of climate change, we'll only make it worse. And it's all America's fault anyway because of their emissions.

When do we vote out ideologues and have logical people in power?

redserk•7m ago
This nuclear argument is getting quite stale. Germany seems to be investing quite a bit in other energies just fine.

https://app.electricitymaps.com/map/zone/DE/live/fifteen_min...

120GW of nameplate solar capacity is nothing to sneeze at even with the latitude challenge. That's more solar than almost all of California's energy generation combined, or most of the eastern United States.

If it's every summer, how is it unnatural? If it's poor planning how is it every summer? There's poor planning and then there's ... what, forgetting that summer happens? It sounds to me like somebody sat down and penciled in some numbers and decided that "it makes less money to let it break?" which seems pretty weird when you consider second-order stuff (but it's not like people tend to do that anyway)
wongarsu•1h ago
Based on the little information provided the AC can't keep up. So they cut off the lower half of the building to provide better cooling to the other half
ceejayoz•59m ago
Which, as heat rises, is probably reasonable.
basisword•1h ago
Presumably the AC systems themselves couldn't operate in that extreme heat. A lot of grocery stores in the UK, which are icy cold usually, had major issues with AC and refrigeration systems failing - I think because a lot of the equipment is on the roof and exposed to the heat.
lstodd•53m ago
AC systems don't quite care about direct sunlight, they are forced air heat exchangers. Now if the condenser (rooftop) side is undersized and therefore inadequate given elevated ambient air temperature all you can do is shut down a portion of evaporation side (the cold one) off, or the entire system just stops working.

Alternatively one can install water sprinkers on roofs like they do in China.

pkaye•44m ago
Its pretty common to se the AC systems on the top of roofs on big buildings in the US. From what I read, exposing the AC condenser unit to the sun should have minimal impact. Air flow through the condenser unit matters the most. Perhaps they were undersized for the extreme heat now happening in the UK.
black3r•55m ago
my guess is that the outdoor AC unit reached its maximum working temperature...

since we're not that used to extreme heat in EU, units with max working temperatures of 45 degrees Celsius are pretty common and the air around the AC unit is warmer than regular outdoors air, doubly so if they're placed on the ground and the glass from the building reflects some additional heat from the sun.

the risk of this was broadcasted in our local news for home AC owners when the forecast reached 40, as lots of apartments have the AC on partly glass-encased balconies, or on walls facing direct sunlight...
