Ah ok. Then I think I understand. For us, they all lead into the technical room in the basement (device not yet installed). Then I assume that a distributor box will be hung on the wall next to the ventilation unit.

With the usual round pipes, the air is distributed via the distribution boxes. These can be hidden in the underfloor construction (very unfavorable) or on the ceiling or walls or also behind drywall enclosures.

Just like with you now. All pipes come together in the [HAR] and are connected to the distribution boxes.

With sheet metal, this can be omitted because the ducts can be very well regulated over the cross-section. This is not possible with round pipes because they always have diameters of 63 or 75 mm.

For our ventilation system, 75mm round ducts were installed in the concrete ceiling. However, the structural builder had to go with a ceiling thickness of 22 cm. And we were explicitly advised against flat ducts - the main argument was that they are difficult to clean. Whether that is true, I cannot say, as we trusted the statements and have round ducts...

I had similar questions at the beginning. Are you building with an energy consultant? The energy consultant will specify how thick the insulation layer in your floor should be. However, they do not calculate for intermediate ceilings. For that, you then ask your plumber. Regarding the thickness of the ceilings: You can have a structural engineer involved already during the preliminary design phase. They can do a quick approximate calculation and thus give you early planning certainty, which is what you want now.
By the way, the architect should know this and, from experience, should be able to assume the correct floor structure. He also studied structural engineering during his studies.

Thank you very much,

for me, however, it comes a bit too late. The building application has been submitted and the construction plans have been created.

The architect was no help in this particular case. He has always installed single-family houses with window rebate ventilators. But he made that clear from the beginning.

Who then went, as you said, to the heater and its specialist advisor.

But we had already decided beforehand to increase the clear height of the ground floor because of the "large" rooms. With that, we are now on the safe side.
