ᐅ Does it make sense to install an air conditioning system?

Hello,
we are soon building an urban villa with two full floors in Brandenburg (Barnim).
Construction method: double-layer masonry (15 cm (6 inches) lightweight clay wall elements + 14 cm (6 inches) mineral wool insulation + 11 cm (4 inches) facing bricks, so a wall thickness of 40 cm (16 inches)).
Now we need to decide whether we require air conditioning so that the construction company can plan the necessary openings and electrical installation accordingly. For us, only a split system for one or two rooms is an option (kitchen, because it gets hot when cooking / living room or bedroom).
Unfortunately, we cannot assess whether it is really necessary, whether the rooms become uncomfortably warm during hot days like the last two weeks, or if they stay cool due to the construction style of a detached house.
Does anyone have any experience?
We appreciate any advice.
Best regards

I would base it on the direction the rooms face and whether there are enough windows for ventilation. In summer, I usually only feel hot inside the house during the day when the air feels stale. In the bedroom—which unfortunately has south-facing windows—there is a ceiling fan above the bed. It works wonderfully.
Solar panels and air conditioning make a good combination; however, I would never lower the room temperature to what feels like a refrigerator, but only a few degrees below the outside temperature. Otherwise, I tend to get a sore throat quickly.

The question is, what temperatures do you find comfortable?
When it’s 30°C (86°F) outside, I don’t want 20°C (68°F) indoors—that would almost guarantee a cold for me.
In our well-insulated new build with automatic shading, indoor temperatures don’t go above 24-25°C (75-77°F). That still feels comfortable and actually cool when you come in from the midday heat.
Sometimes I cool the bedrooms using the underfloor heating system (cooling mode).
So, for me, the answer is that air conditioning is unnecessary.
