I think what you mean I do all by myself. I am a bricklayer in a company and will of course subcontract all trades myself and already have almost all the offers except the one with the heating engineer. Actually, I just wanted to know if I definitely need an Energieeinsparverordnung certificate, meaning if the office will eventually show up and demand it.
There may be a misunderstanding here. But to my knowledge, a thermal insulation certificate is used to demonstrate that a house meets the requirements of the [Energieeinsparverordnung], including summer thermal protection. And at least we had to attach this certificate to the building application for it to be approved at all.
Possibly I have a misunderstanding here.

so the Energy Saving Ordinance was not submitted with the building application (Lower Saxony)
I mean, I would build anyway according to the Energy Saving Ordinance and probably even exceed the requirements, but I don’t need a specialist to tell me what I need if I would install it anyway with thermal bridge details and such fancy stuff.
The building application has of course not been approved yet and is still stuck at the city until it is sent to the district.
The thermal insulation verification according to the Energy Saving Ordinance can only include the building heating load according to DIN EN 12831, as this concerns the entire building.
The room heating load according to DIN EN 12831 belongs to the HVAC system and takes into account every room and its temperatures.
Surface heating systems differ again.
The building heating load is NOT the sum of the room heating loads,
the room heating loads can be up to 30% higher.
