Ceiling outlets for controlled residential ventilation, is that correct?

Hello everyone,

the concrete ceiling needs to be ordered and I am supposed to inform the site manager where the outlets for the controlled residential ventilation should be.

Initially, 100 mm spiral ducts were planned, but this makes the concrete ceiling more expensive etc........ now I am planning it with flat ducts.

The attic is also to be converted.

It is now planned with 6 supply air and 6 exhaust air.

Ground floor:
1 exhaust air will be directly in the utility room
2 exhaust air (guest WC and kitchen)
1 supply air (living area)

Upper floor:
1 exhaust air for bathroom
4 supply air for bedrooms

Attic:
2 exhaust air (storage room and bathroom)
1 supply air for room

Is that okay? Thanks!

For parents make two valves and for living maybe also rather two. And for washing machine/dryer also exhaust air.

Has anyone calculated that or where does the plan come from?

Would the position not matter?

The recess will then be wider, must consider the sink whether that will still work?

Well, as far away as possible from the exhaust or [ZUluftventilen].

In the utility room, the plate valve is directly on the distributor..... I did that with a friend, we first considered which room needs what, regarding the number per room, we always assumed a maximum of one exhaust/supply air.

It depends on the need. As said, bedroom with two people two, otherwise too much air has to pass through one valve. Living room the same.

Exhaust air can also have more air through one valve, as noise or draft is not so critical there.
