ᐅ Mechanical Ventilation with Heat Recovery – Planning the Locations for Supply and Exhaust Air

Hello everyone,
The planning for our semi-detached house is becoming more concrete. Now we need to determine the positions of the outlets for the central mechanical ventilation system with heat recovery.
I have read quite a bit on the topic and tried to consider the usual best practices. However, it is quite overwhelming at first and leaves some uncertainty. That’s why I would appreciate it if you could take a look based on your experience.
In general, everything is initially planned as ceiling outlets. However, the concept of displacement ventilation also makes sense to me, so wall outlets near the floor for the supply air could also be considered. What are your thoughts on this?
Yellow dots = Extract air
Red dots = Supply air
Blue dots = Alternative supply air (as a possible alternative position for the same room instead of the red dot)
Ground floor:
Upper floor:
Attic floor:
Thank you very much in advance!

Ground floor:
- The additional table indicated in the office will ultimately not be placed there.
- I am unsure whether the supply air in the hallway should preferably be near the front door or not.
Upper floor:
- The alternative supply air position is meant to better cover the hallway area. Or is this not relevant, and is it more important that air is supplied directly into the dining/living area?
- Would it be better to have two outlets in the large living and dining area to minimize noise?
Attic floor:
- The children’s rooms are a bit of a headache because it is very difficult to predict exactly how the furniture will be arranged at this stage.
- In the slightly larger children’s room, I’m also not certain about the door position yet. It might be placed all the way to the left (opposite the bedroom door). In that case, the supply air would need to be located elsewhere.
Thank you very much in advance!

Since this is generally about the question of positioning, I would like to use your thread to ask for opinions regarding our current planning. I hope that’s okay? We are planning a mechanical ventilation system with heat recovery and today received the hand-drawn sketches from the plumbing company.
To my knowledge, orange indicates exhaust air
Purple indicates supply air
From the plan, as a layperson, the following questions arise for me:
Basement: looks plausible to me at first, and I assume the air from the granny flat will flow through the hallway into the basement
Ground floor office: I wonder if the position of the supply air above the seating area is well chosen? Wouldn’t you feel a constant draft there? Would it make more sense to place it in the bottom left corner?
Ground floor living room: is the distance to the sofa sufficient, or would there be a noticeable draft? If so, where would be a better position?
Upper floor dressing room: I don’t yet understand where the exhaust air is supposed to go since there is a closet right there. But I assume the planner knows what they are doing
Upper floor Child1/Child2: I once read that the supply air should not be too close to the door to ensure proper air mixing in the room. Would this be achieved here?
If you need any more information, please let me know. Although I currently don’t have much more info myself.
Thank you for your support!
