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.

So, our KfW application from January this year included the type of ventilation. You are right about the KfW application. That's true. The building authority doesn’t care. Just to make sure we’re not talking past each other 🙂

But you have to decide how you want to implement it when submitting the KfW application.Not exactly. You state how you intend to achieve your energy standard. You can also easily deviate from it, especially if you choose better technical solutions. Controlled residential ventilation instead of opening and closing windows. Geothermal energy instead of gas. And so on.Central ventilation systems have been proven reliable for decades, and many of the earlier myths about them have been thoroughly debunked. But like many things on the internet, such conspiracy theories just won’t go away.
To maintain good indoor air quality, you need to ventilate every 2 to 3 hours. Just the fact that I want to sleep at night without constantly having a window tilted open in winter made it clear to me that it basically doesn’t work without a ventilation system.
No clay plaster or other gimmicks can help against CO2.

There are many ways to achieve a comfortable atmosphere in a house. A well-adjusted and properly installed mechanical ventilation system with heat recovery is one of them. For those who don’t prefer this method, there are other options available. This is not a conspiracy—just facts that can be measured for skeptics or those particularly interested, such as humidity in % and CO2 in ppm, etc.
