That cannot be correct, we are building a larger corner and have a primary energy demand QP of 23.4 kW/h.

but per sqm, the size is already factored out there?

Our 1st version was also faulty, I inquired again, it was then changed.

    [*]Heated building volume 1386.8 sqm
    [*]Heat-transferring envelope area 745 sqm
    [*]Usable building area 443.8 sqm

23.4 kWh/m²a (?) - he has 31.6 kWh/m²a, that is not so far off..

Well, we are building about 50% larger and have about 25% less primary energy demand QP. So I would at least follow up on that.
