Energy demand certificate for new construction

What is an energy savings certificate? New building! Which energy do I want to save if I don't even have any consumption so far?

There is only one energy performance certificate (in two variants) and both may only be issued once the object is completed.

This is the paper that the bank wants for the KFW 153 application. We got it at least directly with the contract signature and it looks partly similar to the energy certificate. It contains all the calculations for the individual components, etc. Someone from the field can probably explain it better here.

No, this is the online confirmation and it is black and white. The bank does not need more for the KfW.

No idea, with us it says "Energy saving certificate according to the Energy Saving Ordinance Energy Saving Ordinance 2014" on the front. And there is a page ("Efficiency level") that looks like the energy performance certificate (and yes, black and white). The question is what exactly the OP has.

We have already received the [Energieausweis] in advance. It also had to be determined exactly which technology would be installed.
