Effort and additional costs for proving KfW55 standard

Good morning,

can you tell me how much additional effort it is for an architect / structural engineer to provide the certificates so that the new building meets the requirements of the Kfw55 standard and the subsidies are granted?

We gave the architect the requirement that the house would theoretically meet the KFW-Standard 55. However, it was left open so far whether we actually want to take advantage of the subsidies.

We have now agreed on a fee. When asked, it was said that the fee would increase by €5,000 if we need the proof that the house meets the Kfw55 standard in order to be able to claim the subsidies.

Is that justified? Is the additional effort that the architect has to undertake so high that he is entitled to a fee that is €5,000 higher?

We are talking about a classic single-family house with 170m². 1.5 storeys. The architect is commissioned for all LPH and also takes over the structural analysis, as well as the thermal insulation certificate, heat load calculation, and whatever else is needed. He is also an energy efficiency expert.

Please don't get me wrong: if the additional effort is actually that large, then he deserves his fee. However, it seems to me somewhat high in relation to the actual fee. Of course, I have no idea how much extra work it is for the architect.

Regards,
Sebastian

Good morning,

can you tell me how much extra effort it takes for an architect / civil engineer to provide the proofs so that the new building meets the Kfw55 standard requirements and the subsidies are granted?

We gave the architect the instruction that the house would theoretically meet the Kfw standard 55. So far, however, it has been left open whether we actually want to take advantage of the subsidies.

We have now agreed on a fee. Upon inquiry, it was said that the fee would increase by €5,000 if we need the proof that the house meets the Kfw55 standard in order to be able to use the subsidies.

Is that justified? Is the extra effort the architect has to make so high that he is entitled to a €5,000 higher fee?

We are talking about a classic single-family house with 170m². 1.5 stories. The architect is commissioned for all LPH and also takes over the structural analysis, as well as the thermal insulation verification, heating load calculation and whatever else is needed. He is also an energy efficiency expert.

Please don't misunderstand me: If the extra effort is really that great, then he deserves his fee. However, it seems to me to be quite a lot compared to the actual fee. Of course, I have no idea how much extra work it is for the architect.

An energy consultant including supervision and documentation costs around €2,000 according to my experience. In this respect, €5,000 would be too much. But maybe the architect also has more effort through Kfw that he charges for. I am ultimately not an expert, but I consider it to be too expensive.
