Are the supply and exhaust air valves okay?

Hello,

I have received the calculation of my controlled residential ventilation from the heating engineer and he told me to consider where the valves should go.

I have marked it on my floor plan. What do you think about it?

Red = exhaust air
Bau = supply air
One hose per circuit

Spontaneously, I would say blue and red directly next to each other!? Then the supply air would go directly into the exhaust air. Pointless!

Basically:
Living rooms = supply air
Bathroom, kitchen, utility room, upper floor corridor possibly exhaust air
I would place them, where possible, close to the wall (min. 30cm distance from wall/corner)
Place supply air far away from a door.

Where the red and blue circles are directly next to each other, the pipes go up in a cavity wall to the attic. There are no [Tellerventile] there. Only where there are single circles or a maximum of two circles, a [Tellerventile] is installed. I chose the colors poorly for the riser.

Sleeping rooms, living rooms, supply air, bathrooms, storage room, kitchen exhaust air.

In principle, one should always choose the most remote locations in the room. Overflow in the frame and not through the door gap. Even better would be supply and exhaust air room-wise.

But something like that is actually a task for a planner.

Is there anything against the planning? The plate valves and pipe layout were calculated by the heating engineer. I was only supposed to choose the locations where they should go. And I tried to stick to that: 1m from the wall, so that the air is not largely deflected along the wall to avoid drafts, and as far away from the door as possible.

There are more valves on the upper floor.

35 cm is more than enough and further away from the doors you have to let the room flow through but of course take into account that there are no windows nearby. Although with [wohnraumlüftung] they are rarely opened.
