Blower Door Test - Meaning of the Result

It is usual shortly before handover. Our first one would not have been recognized by the KFW. We have to be better than 0.6. That is why one was carried out as early as possible. The second one for the KFW was only carried out after moving in and replacing the complained-about windows. Not much has changed. Test 1 0.42 Test 2 0.35

I haven't followed your topic... what was with the windows? Did the first test show that something was wrong with them?

No scratches. Someone was not careful between window installation and acceptance. 2 regular windows, 1 balcony door, and the sliding lift door had to be replaced

In our construction service description, it states that the blower door test must be paid for by the client themselves if it is even desired. Then I hope I don't have to pay the 550 euros too often when I read this here.

Normal is a test The majority of companies pass the test on the first try. The only question is whether with an excellent 0.6 or a poor 1.3. We had 2 because it is a Passive House and completely different values must be met. 1 x the one that makes sense from the construction process 1 x the one that [KFW] requires

We have a value of 0.64 right away.
we would have needed better than 1.5.

We have KFW 55 with ventilation system.

So we have almost passive house standard. But according to this thread, it doesn’t seem to be uncommon.

One can also submit exemption applications if economic viability is not given, etc.

Are there proven cases where this is not the case?

So someone who in the specific case consciously chose a KFW house for cost reasons because the additional effort or higher cost pays off after 10 years?
