Reliability of an energy calculation for KFW55, too high?

Clearly shows once again that the KFW specification simply doesn't say anything. We have KFW70 and are at a calculated 38kWh/m²...

I already wrote that... many factors - especially with [Primärenergie]. In addition: if I build a house out of windows, it will turn out significantly worse but might even achieve [KFW40].

Just shows again clearly that the KFW rating simply doesn't say anything.

Well, it's not quite like that.

No, not that bad, but what some people think, that they have built a house with [KFW55] for an incredibly high standard :D.

Better put: It only says very little about energy consumption - today even less than "before".

The KFW standard is not meant to compare the euros in the wallet.

The absolute value already says a lot (under laboratory conditions).

And a normal house of this building type would require even more energy. That’s what it indicates.

Anyone who wants a nice, individual house shape (or is forced to due to building authority requirements) has to pay the price for it.

Considering that every room here has four exterior walls, I find the value very good.

How many rooms does your house have?

I know what the KFW value stands for, but apparently many others don’t, because they only see the value and then say a house is good/bad...which is just nonsense.
