ᐅ Construction supervision and energy consulting for a KfW55-standard home combined in one role?

Hello,
we are planning to build a KfW55 energy-efficient house. The construction will be supervised, and for the KfW55 loan, we also need an energy consultant.
I just noticed that the local homeowner advisor from the Bauherren-Schutzbund is also a KfW energy consultant. Does it make sense to have one person fulfill both roles to save travel time and costs, or should these tasks be handled by separate individuals?
I assume that the general contractor will also suggest someone as an energy consultant. Would the combination be more efficient than choosing someone independently, or does it not make a difference?

Thank you

We are asking ourselves the same question, especially considering the KFW 431 program, which offers funding of up to 4000€ (euros).

As far as I know, only the building surveyor and energy consultant must be economically independent.

From a legal perspective, this should be acceptable in my layman’s opinion.

I would definitely not use an energy consultant proposed by the general contractor; independent verification is not required without reason by KfW either...

In this context, "well-practiced" sounds more counterproductive for proper inspection to me.

The wording I use is my own, not that of the main contractor. I have not yet thoroughly dealt with the topic of energy consultants.
My thought was that the in-house energy consultant knows the building specification inside and out and therefore requires less time.

That’s also how I understood it—that it’s your choice of words. However, construction supervision also involves monitoring the build. And someone who is close to the construction company is, in my opinion, not the right person to oversee matters that might potentially cost the general contractor money. Personally, I would prefer to have someone who is independent.
