Hello,
I have now received the first draft of the ventilation layout plan from the professional. He designed on-floor flat ducts (so far, I haven’t found any solid disadvantages compared to in-floor round ducts).
In the basement and ground floor, air supply and exhaust outlets are planned in the ceiling, which is not a problem.
In the attic, however, he does not want to do this because the ducts would have to run through the uninsulated/ unheated attic, which could cause condensation inside the duct system—this would not be good.
Therefore, the supply and exhaust outlets will be installed in the walls. Exhaust air at 2.20 m (7 ft 3 in) height, supply air at 0.5 m (1 ft 8 in) height.
These are planned, as shown in the attachment, nicely positioned in the corner, which I think would create an optimal airflow path.
However, beds are often placed in corners. Having a bed in front of the supply air outlet sounds rather impractical. Firstly, because the opening would be blocked by the bed, and secondly, because it would cause a draft while lying in bed.
Wardrobes will go along the long free walls. The two windows in the cross gable are floor-to-ceiling, the others are half-height windows. I understand that under the half-height windows a desk is often placed, allowing a good view outside. The latter is definitely a debatable point, but I don’t want to discuss it at length.
In my opinion, the exhaust air outlet at 2.20 m (7 ft 3 in) height can stay in the bed corner since I sleep low and wouldn’t notice it.
The issue mainly concerns the two children’s rooms. Here I was thinking that the supply air outlets could either be placed right next to each of the floor-to-ceiling windows or in the wall between the two children’s rooms.
What are your ideas and concerns about this?
Do you see the condensation (dew point) issue differently? I still believe that having supply and exhaust outlets in the ceiling would be the nicest solution.
Thank you very much.

Exactly, it works… Dirt, dust, pet hair, etc., cannot accumulate there because of the constant airflow… we are not here to convince you… we are simply sharing our experiences and observations.
The video only demonstrates the physical principle. Of course, the effect at the controlled ventilation outlet is less and not strong enough to levitate a tennis ball, but it is sufficient to keep common household dust and similar particles away.
Here are two pictures showing the condition after 6 years of continuous operation. They were not specially cleaned but only vacuumed and wiped damp regularly. Sorry for the quality; they were quickly taken with a phone. One without and one with the grille.
By the way, we have two indoor cats, so there is definitely no shortage of loose hair.

The appearance should not be an issue, as floor drains come in a wide variety of options (size, shape, color). If you don't like ours, that's fine... it’s really just about having the option. In my opinion, a floor drain on the upper floor is the simplest and most cost-effective solution for everyone... meaning there are plenty of other areas in house construction where money can be spent or lost.
