Yesterday, the blower door test was conducted at our place. Unfortunately, we were not informed beforehand that it would take place. I find that unfortunate, and I would have liked to be present. In our documents, I only found a note that the test is required for KFW, but no specific regulation about it.
We are very satisfied with the general contractor, but still, I would have wanted to be there. At handover, we will receive a sheet without having been able to verify the values myself.
How much does a test initiated independently usually cost?
How did you handle this?

He also covered all costs even though it was not included in the contract. It was some time ago, and without having the documents at hand, I believe I recall that it was part of your contract 😉Regards, Bauexperte

Regards, Bauexperte 🙂 ah, no desire to look into it ^^

Just ask your general contractor (GC) about it.

A blower door test does not make much sense any longer when the house is about to be handed over; two of them even less so 😉

We had an airtightness test conducted before plastering began (similar setup to a blower door test). The planner and the general contractor walked through the house together, checking by hand and with a device to feel for any drafts. The main focus was on the windows and the top airtight layer.
Apparently, there will be a blower door test again at the end.
According to Wikipedia, for low-energy houses, the air change rate under test conditions (50 Pa pressure difference) is typically between 1 and 2 per hour – so your 0.98 per hour seems quite good.
