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.

Heating and ventilation are indeed closely related to how much energy a building consumes, and optimizing this is certainly reasonable. However, it is not about short-term savings like opening a window to turn off the heating, but rather about the long-term processes and their control.

So far, I assumed that the key point here is especially "heat recovery" and that the two devices probably need to communicate with each other to work more efficiently!?
