ᐅ Energy Saving Regulation / Thermal Insulation Certification Offer

Good evening,

I am unfortunately completely inexperienced in this area. We are planning to build our own home in the near future, and now the heating contractor wants the energy saving regulation in order to provide his offer.

My question is, does the energy saving regulation need to be prepared by an energy consultant? As far as I understand, the exact U-value requirements are publicly available. Nevertheless, we asked for an offer with the following costs, which I find quite high.

For energy saving regulation and possibly KfW:

Thermal protection certificate / energy consultation: 1900€
Basic flat rate for detailed energy planning: 2500€
Optional detailed thermal bridge analysis: 2200€ for 20 hours
KfW application processing: 900€
Blower door test: 450€
Spot checks: 720€ per 240€
Energy performance certificate: 250€

Gross total: 7997€

Best regards

Does he need the thermal insulation certificate? Or a room-by-room heating load calculation?

What exactly does the architect do? In the end, you end up paying twice for half of it. It’s not cheap, and it’s completely uncertain what you actually get.
The heating engineer basically needs the heat load calculation. If they want proof for the energy-saving regulation compliance, they might as well just guess.

I'm not an expert, but in our case, for example, the plumber/heating technician did the calculations. Isn't that normally part of their job?

Apparently a thermal insulation certificate is required to create the heating load calculation.

The architect has already done his part and supported us up to the building permit / planning permission stage. Nothing more was agreed upon.

I have no clue, that’s why I’m trying to gather some experience from you all ;D

I feel the same way; it was more of a naive question aimed at the group.
