Hello,
I have received my calculations for my house, and they seem quite high?!
Building volume Ve = 875
Envelope area = 610
Usable floor area An = 280
My living area is about 230 m² (including balcony, terrace, etc.) (balcony + terrace are about 20 m² (215 sq ft))
The problem is that all the calculators I have used come up with a heating load of around 7. That sounds very high to me for a KfW40+ standard. What do you think?
The actual heated living area is only about 170 m² (1,830 sq ft). Everything else consists of utility rooms in the basement, balcony, etc.

I’m not familiar with the exact numerical value for the ventilation. But maybe that’s where the problem lies?
With controlled residential ventilation and heat recovery, I come to just under 5 kW.
Edit: I just noticed in the fine print 2.9 kW from ventilation losses. In my view, that would mean you don’t have controlled residential ventilation?
