It would often only have been really impactful for one or two weeks a year. Not really worth the investment.
With temperatures climbing this high, and being maintained for longer periods, I recently bought my first mobile AC unit and am thinking about installing a permanent one after the summer.
1. Set up AC company in Europe
2. Wait for panicked calls from sweltering people
3. Profit!!
Having lived in south France, where temperature was always over 30C in summer for long period of time. There simply wasn't air conditioning in homes or offices. It's not that it isn't needed. It's just not there. If you want to change job to an office job with AC, good luck finding one.
You're just burning down in summer? being completely unproductive at work? People just live with it. Dress in short tshirt and drink a lot of water. There can be 50 employees asking to get a AC unit for the floor, doesn't matter, management is just nope.
It's evolving slowly as new office constructions have air conditioning and it's being retrofitted to some places.
