ᐅ Building Energy Act Calculations – Are They Required? And Who Prepares Them?

Hello friends,
So far, we do not have an energy performance certificate or calculation for our new build (single-family house, not for rental). The architect planned with 36.5 bricks, there is a ground-source heat pump, and a central ventilation system with heat recovery.
The general contractor building for us says they never do the energy performance calculation.
The expert we hired to inspect the build (starting in October) says that a calculation is necessary, at least to correctly select insulation materials, wall thicknesses, etc., and that it should come from the general contractor.
Now I am confused, so here are my questions:
1. Who is usually responsible for this?
2. Do I have to commission it myself? From what I understand, I must of course comply with the energy performance regulations / building energy law, but no official from the city where I am building will actually inspect or measure anything inside my single-family house after it is finished, right? And I would only need proof when selling or renting it out – correct?
3. If it is not possible without the calculation, how much does it roughly cost? Can someone share their experience?
Thanks!

Yes, in Bavaria. No, we did not submit it and it was not required, and the application has since been approved...
Have you read the entire approval? Including the additional conditions?E

I've now commissioned it. Better to have it and not need it than the other way around.

I assume that nothing would be applied for that is not permitted anyway. And if the building is constructed according to the Building Energy Act or the old KfW 70 standard, no explicit application or specification with calculation is required in the building permit / planning permission. How is compliance ensured without the calculation? Perhaps just by estimation, like “looks good...” ;-)Similar topics
