maybe it also depends on where you live – I don’t know that, and there are certainly areas where it’s generally cooler and where you really let in everything possible when the sun is out.

I assume Munich and OWL, and from both areas I can say, based on temperatures of recent summers and the good insulation of new houses (and here we only have a 55 standard), of course it’s not 30°C inside – because during the day we close up everything possible and don’t have any windows open. Not because we throw everything wide open in the evening. We’ve tried that overnight too. One window open, in the attic one window open, and a fan up there running to circulate the air once.
That only brought a 1-2° drop over the entire night.
But we don’t like it hot anyway and we don’t really sleep well anymore even at 25° in the bedroom.

One fights the symptoms of a trend instead of rethinking the cause, as large windows as possible. :D I can only laugh at that, with our normal casement windows without a 5m glass front. We have brightness, a good view, no expensive shading, and pleasantly cool. Unfortunately, it's not trendy at all, I don’t care :D

We have exactly this problem in the attic, which is very well insulated. During a heatwave, the attic is for quite a while the coolest room in the house (old building). But if it lasts too long, several days, the walls heat up despite closed shutters so much that it takes several more days to cool down again. And if I take our attic, which only consists of our bedroom and has windows on three sides (west, east, south), and if I create a draft there at night, it’s barely the 22 degrees that are outside, but woe betide me if I close the windows, e.g. because starting at 5 am you can hear car doors, cars, etc., and because it’s already light outside at 5 am in summer, then it suddenly gets noticeably warmer up there again right after closing the windows. I can hardly sleep as it is, I hate heat, without completely tight shutters I would give up and rather move to the living room. Without shading… no, I don’t even want to imagine that.

Here, the last summers have been warm until late into the night, it was almost unbearable. You open the windows in the evening and it only brings lukewarm drafts. It only gets noticeably cooler on such nights after 1 a.m., and on the ground floor you don't want to invite unwanted guests, so you have to close the windows again when you go to sleep. Our alarm clock rings at 6:15 a.m., which means we don’t go to bed at 3 a.m.

The trend of huge glass surfaces, as much glazing as possible for the air space, sleeping on the upper floor is unbearable in summer without air conditioning. If dark facades become fashionable now, instead of white, [Photovoltaik] cannot generate enough electricity for the air conditioning.

Fortunately, except in the attic, we only have windows facing east and west, not south. As typical for old buildings, we also don't have much window area, THANK GOD. We have good insulation, but during longer heat waves even such a house heats up unpleasantly.
