Hello, we are having a house built Kfw 40 timber frame house without a ventilation system.... Today I received the data from the blower door test.

Result 1.7 With two indications of air infiltration points

Leaky at all inspection openings of the roller shutters due to the construction

And a hole in the vapor barrier foil of the ceiling slab possible moisture damage in the insulation layer.

Test is passed do I have to accept it as is?

I am an absolute layman and grateful for any tips

I also had modest results and caused drama. You may have to accept the passed test, but all construction defects should be remedied. Especially with the vapor barrier. How far along is the construction, interior cladding already on it? Perform a second test during or after defect remediation.

Hey no ventilation system

Yes everything is already clad from the inside... Test was done a month ago but I only received the results now...

Was it only clad or plastered over in the meantime?
Have the defects been rectified?

No, it was already plastered and covered before...

The holes where the electrical cables come from the ceiling for lamps or spots were recorded in photos.

I don’t think anything was fixed...
But I will call the construction company tomorrow...

But they have to fix the recorded issues, right?

Window certainly with window rebate ventilation, right? The result is OK for that. The limit value is 3.0. The mentioned notes, especially in the vapor barrier, cannot be proven anyway, so they are also difficult to fix.
