Energy Saving Ordinance, KFW55, KFW40 or KFW40 Plus

40+ for 40+.

Sounds about right, and I don’t think it’s completely unreasonable...

Ok. I understand that it is currently not financially viable.

What about the preservation of value and future viability? Will there even be gas connections in 20 years? And so on...

In 20 years I will install a fuel cell in the basement, he doesn't care whether the house has a KWF poster or not. A new building according to the Energy Saving Ordinance is energetically already so advanced that in the future there should probably be no problems concerning heating costs.

Phew. Somehow sobering. And turns everything upside down...

Well, that's a bit of a cliché from me now

I don't know what will happen in 20 years, whether there will be a fuel cell or not.
But what I do know:
I definitely won't spend 40,000€ anymore just to save 100€ a month on electricity and heating.
And even those 100€ I consider to be an overestimate, because complete self-sufficiency probably won't be achievable anyway, that's how sure I am.

So just let everything settle a bit until the sobering up is over, then it will also become clear from which motivations one would like a KFW house.

Well, we still have two appointments next week with absolute KFW opponents. Let's see what it brings.

Perhaps the desire to build with the company from Bad Fallingbostel is behind it. Reasons: schedule certainty, cost certainty, assumption of building ground risk, and transparency. We already have serious concerns that the construction will financially ruin us due to expensive additional financing.

*Transparency regarding the costs
