Hello everyone,
We are going to build a single-family house to KfW55 standard. It will have a basement, ground floor, and upper floor. The living area is approximately 170m² (1830 sq ft) and the usable area 108m² (1163 sq ft) including stairs and basement – that’s the basic information.
Now we are wondering which ventilation system to choose, since new builds are very airtight due to the windows and insulation.
We were recommended a decentralized system, as it would be fully sufficient and requires less frequent maintenance and cleaning. Additionally, cleaning is easier and less problematic compared to a central ventilation system.
Could you share your views or experiences on which ventilation system would be most suitable?
Thank you very much.

I have the Zehnder Q450 with a similar square meter area.
Very satisfied... but I would recommend ordering the enthalpy exchanger from the start.
75mm (3 inches) diameter ducts in the concrete ceiling... works well.
No noise at the lowest setting – minimal, only in one room at the standard setting.

We will probably go with a Zehnder system, as it is supposed to be really good.
I have a question.
We are adding an apartment for my mother-in-law, about 70 sqm (750 sq ft).
So we have 140 sqm (1,500 sq ft) plus 70 sqm (750 sq ft), all on one level.
Could this work with a single system? Or would two be necessary?

So it should work for you as well.
A small issue could be the regulation. If your usage increases (showers, guests, etc.), it will also increase at the main unit – and vice versa...
