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.

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

In which case it would be just plain bad design if you can't have the whole building on AC when you actually need it...

Edit: it'd be interesting to know how many buildings in Belgium have had the same issue.

You can leave it on when you actually need it - meaning all summer long, in the conditions that are typical for that location.

It's like saying what's the point of having a house if you aren't safe in it during a tornado. It's an exceptional event. The problem is that these truly exceptional events which only happened once every 10 days for a day or two, are now becoming a norm. My own 12k BTU minisplit could cool my house down every summer, no problem, even down to 18C if I wanted it to. But in the recent heatwave it just can't keep up, there is more heat coming into the house than the system can remove.
