Tasks of the EEE in BEG individual measure (Bafa)

We had an extensive roof renovation carried out for a house with an extension (new construction of the roof truss on one part of the building, conversion from a pitched roof to a flat roof on the other part of the building). To receive the subsidy, we hired an energy consultant. Scope of services: checking the offers for eligibility for funding, application submission, checking the invoices. According to him, the offers are eligible for funding.

In addition, he is preparing the thermal insulation certificate for the building authority.

The measure is almost completed and he is now preparing the thermal insulation certificate. In doing so, he mentioned that he has now noticed that there will be massive condensation in one roof structure and that the other roof structure accounts for a comparatively large proportion of the building envelope, so a ventilation concept for the attic might possibly need to be made.

Shouldn't these two points have been noticed during the offer review?

It is clear that he should not provide me with a finished ventilation concept, but at least a hint like "hey, you probably need active ventilation here, better plan for it or let us calculate it" BEFORE everything was built would have been good. Now I have to reopen parts of the roof to replace the insulation (PIR to mineral wool because of the dew point) and to provide ventilation slots.

He said that this is not part of the BEG EM funding, but that he would look at the condensation as part of an energy consultation and the ventilation issue in an iSFP.

New windows? Then a concept is mandatory. Otherwise: special service for money

And why condensation water? Maybe you tell us exactly what it's about.

Where does it say that the concept is mandatory for new windows or analogously for all other measures?

Our roof renovation includes a new roof structure including insulation, new floor ceiling, partial changes to the exterior walls, dormer, terrace door, etc. So actually almost every building component group is involved.

Where does it say that the concept is mandatory for new windows or analogously for all other measures.

DIN 1946-6

According to the commissioned scope of services, your energy consultant does not have to do anything there. He only checks whether the offers are eligible for funding. If, when checking the U-value, he notices that the construction is nonsense and tells you, that is benevolent kindness.

The planning and checking of the construction can be commissioned, for example, it was part of the preparation of the iSFP in our case.
Who planned for you? That person is responsible, provided they were commissioned for it. With such a conversion, you certainly do not let the contracted construction companies / craftsmen do that, do you?

Because they usually have something like this in the fine print:

We exclusively deal with the trade of building components. Consulting services and planning activities, such as construction details and statics, are not part of our scope of services.
We do not check tender documents and drawings for correctness.
We point out that the required specialist planning for the creation of a ventilation concept according to DIN 1946-6 is not provided by us. If interested, we can gladly give you contact details of specialist planners.
We have not checked public regulations and restrictions by third parties.

Where does it say that the concept is mandatory with new windows

This is an indirect requirement from the Building Energy Act (§13) and the DIN mentioned by .

Our roof renovation includes new roof construction including insulation, new floor ceiling, partial changes to the exterior walls, dormer, terrace door, etc. So basically almost every component group is involved.

I'll just boldly ask now, who took over the planning services? The energy consultant only checks whether the measures are eligible for funding (U-values etc.). You can build complete crap that is eligible for funding but technically a disaster.

We had an architect with us who then involved the energy consultant for all the topics.

So what about the part in the guideline: The energy efficiency expert must provide at least the following services as part of the support of the construction measure during the energetic renovation with individual measures and confirm their program-compliant implementation

And further: explain the eligible costs as well as confirm compliance with the technical minimum requirements according to the BEG EM for this measure

First sentence of the technical minimum requirements (which are to be confirmed as part of the TPB): In renovation measures – especially on the heat-transferring building envelope – it must always be checked whether measures for moisture protection, in particular to prevent condensation and mold growth by maintaining the minimum air exchange and minimum thermal protection in connection with the renovation measure, are necessary.

Why are you fixated on the energy consultant? If the construction is botched, your architect has failed. Approach him. You have better chances there...
