Well, that's what I mean. Discrepancy to what? "But I heard different values in a forum." ?
Heaven help .... You write: "
I was a bit puzzled by the primary energy demand in our thermal protection verification. Isn't almost 50 kWh/m2a a bit too high for a KfW55 house?" There is a lot to read in forums, whether it's always correct, it doesn't say there; apart from the fact that two houses of different construction and location are not comparable. So what do you lose if you ask your structural engineer exactly this question? PS: if the calculation is correct, no one – except your structural engineer – will notice if you blush a little out of embarrassment :D Rhineland greetings
