Our house was completed at the end of 2005. At that time, the regulations regarding thermal insulation were certainly not as strict as they are today, yet I still find the insulation to be, in my opinion, completely excessive.
A few weeks ago, when the mornings were still pleasantly cool, I tried ventilating the ground floor by cross-ventilation to lower the temperature to 20°C (68°F). After closing all the windows, it took less than an hour for the temperature to rise back up to 24.4°C (76°F). It goes without saying that
- all the heating systems were turned off
- such temperatures are not healthy over the long term.
The insulation craze is especially noticeable in the attic, where temperatures of 30°C (86°F) under similar outdoor conditions are common.
After careful consideration, I recently had an inverter air conditioning unit installed in the attic (I work exclusively from home), which has definitely greatly improved the living comfort.
However, to what extent this is compatible with the fundamentally good idea of reducing energy costs—especially considering the expected rise in peak temperatures due to climate change—is something I still wonder about...
Are there other ways to lower the basic indoor temperature to a healthy level (21-22°C / 70-72°F)?
P.S.: There are plenty of search results when looking up “insulation madness”... it makes you wonder if someone suspects something.

Maybe you should mention where you live, because it wouldn’t be above 20°C (68°F) in your house either. Greetings from the extremely hot southwest!!! I’ve added it.
I think we are one of the hottest regions in Germany.
But luckily we are a bit out in the countryside – in the cities it is even warmer due to the heated façades, streets, and so on.

We also have 10 to 15 coolers without air conditioning.
At night, the temperature drops, and by manually ventilating, we cool down by about 2-3°C (4-5°F), which is roughly the amount it heats up during the day.
This will only not work tonight because the lowest temperature won't fall below the indoor temperature.
Shading and insulation keep the heat out, while the open windows let in the cool night air.
