Tasks of the EEE in BEG individual measure (Bafa)

We had an architect with us,

And he probably planned a mess.

The condensation problem is due to an incorrectly chosen insulation material (the EEE himself said this), otherwise everything is correct and well constructed. And I would have seen the insulation material in the competency area of the EEE, not detailed with the architect.

But then I'll approach him again.

We have now spoken with the architect, he thinks it is a solution for us that will also be cost-neutral (I am curious) and will get back to us on Monday.
Still, again about the energy consultant.
Does he really not have to provide any evidence at all? He has to confirm quite a bit with the [TPN], right? How does he do that? Only based on the invoices from the trades?

Does he really not have to provide any proof at all? He has to confirm quite a bit with the TPN, right? How does he do that then? Only based on the billing of the trades?

I am EEE and no, he does not have to provide proof. He has to confirm eligibility for funding, and this can usually be done based on the quotes or billing.

How do you then bypass the ventilation concept for the customer? It is required according to the guideline for the building envelope.
