I have a floor that needs to be raised and ventilated. To avoid building too much height and to accommodate the ventilation, I was thinking of using 45x45 (similar to Nivell). I'm having trouble finding 45x45 joists that are C24 graded; will C14 work with close support plates/shims (c/c 350)?
If it will work or not, I don't know, but do I understand you correctly, that you are going to have a wooden beam against the slab? Isn't the point to move away from that?
Nivell can build as little as 15 mm so from that perspective, it's also a questionable reason. However, your solution might be cheaper.
Another thought that spontaneously strikes me is whether you get good airflow with entire beams lying against the slab and subfloor.
I might be misunderstanding something.

If it can help your solution, you can first lay a layer of plastic garage/balcony flooring, which will give you your air gap that you can then ventilate. Then you can lay parquet or any surface layer of your choice, and you have a construction that builds minimally in height.
