We will have a mechanical ventilation system with heat recovery, so that shouldn’t be a problem. Without mechanical ventilation, just ventilate as usual, like in other houses. Although wooden houses generally don’t retain moisture like masonry walls do.

I wasn’t referring to construction moisture, but rather the humidity in summer, which can condense on the (external) basement walls when the dew point is reached. I would have assumed that special measures would need to be taken for a wooden basement (higher air exchange rate, additional vents or exhausts, wall cavity ventilation, etc.), but I’m not sure. It would be interesting to know.

How exactly would the wooden basement in your example differ from a "conventional" basement?
With insulation, the U-value should be roughly the same, as well as the dew point shift. I don’t really see a reason for it, unless there is some kind of air layer somewhere in the wall structure. (???)

The difference is that moisture occurring in a concrete basement drips down the wall and later evaporates again without causing damage, as long as it is not a permanent condition. A wooden basement is likely to be much more sensitive in this regard, since drying out towards the outside is not possible due to the membranes in the basement area.

Just a quick question: How long does it usually take from excavating the basement pit until the basement floor slab is ready (gravel, compaction, formwork, insulation, etc.)? Do you think it will be done by the end of next week? This was started yesterday. I assume the entire basement will be excavated today and the ground will be compacted.

I need to get this off my chest because I was at the construction site earlier. My neighbor had his waterproof concrete basement installed today. The gap between the basement walls was sealed everywhere with expanding foam. I thought I couldn't believe my eyes. Great waterproof basement.

Is the basement made of cast-in-place concrete or precast elements?

A question about your wall panels: why are there bricks placed on top of them?
