ᐅ Alternative to Centralized/Decentralized Ventilation

Hello everyone,

I recently joined this forum because we are currently quite frustrated with the topic of ventilation.
Our construction project starts at the end of April.
It is a solid brick/Poroton house, a single-family home with 200 m² (2,150 sq ft) of living space on two levels. KfW 55 energy standard.

I can’t really explain it, but I can’t decide on a central ventilation system because of the long duct lengths inside the house. I know that all pipes are clean and protected by filters, but my gut feeling just doesn’t agree.
With decentralized systems, we are bothered by the fans on the exterior walls in every room.

Now we are looking for an alternative.
We also didn’t find window frame ventilators very appealing.

So my question is:
Has anyone else experienced this or does anyone know of another system?
We learned about a system available through Baufritz houses with air transfer grills. However, it is only distributed through Baufritz.
It’s a central ventilation system that blows air directly into the house over a short distance and then distributes it further via transfer grills above the doors.

I look forward to your input and help.

Open and close windows.

Listen to your head, not your gut = (central) controlled residential ventilation

Psychotherapy? Central heating system and that's enough.

Yes, it’s completely logical that a central ventilation system would provide the best comfort. But my feeling... actually unfounded. Yes, I think psychotherapy would be helpful. Because there are still so many decisions to make.

But... does anyone know of a system similar to the one from baufritz?

Not me, but it sounds like the window rebate system.

Either controlled ventilation or manual! I rule out manual for 200 m² (2,150 sq ft).
Honestly, I don’t understand your problem: with underfloor heating and cold and hot water piping, you probably don’t fuss much either. You drink the water, and you breathe in the vapors.
Where on earth is the issue with the pipe length?

Yes, it has been installed for over a hundred years. It is called poorly installed, drafty windows.
