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.

Yesterday outside: 36 degrees... inside 22 to 23. In the bedroom constantly 20 I assume the air conditioning is connected to the central ventilation system?
What should I type into Google to learn more about this?
Because I don’t think we will have significantly milder summers in the future.

There will be a photovoltaic system installed on the roof. I’m not completely up to date. Is the generated electricity mainly used for self-consumption, with only the surplus fed into the grid?

I’m not completely up to date. Is the electricity generated primarily used on-site, with only the surplus fed into the grid? The goal is to use more than 70% of the generated power directly on-site. This includes the electric car from 5 p.m.
After all, there is a 8.82 kWp system installed on a purely south-facing roof.

We will install photovoltaics with a 16 kWh (16.8 kWh) storage system (search for pylontech 16.8 kWh).

And regarding Google, I meant the air conditioning, not the solar energy : )
