the thing with the energy certificate is a tricky one, I also had long talks with the energy consultant and eventually gave up. For me, the final energy demand is 47kwh/sqm including auxiliary energy (so with hot water). But that is the amount of heat I need (since district heating is my energy source). For you, according to the energy consultant, the electricity consumption is stated... total nonsense in terms of comparability.
If you have 25kwh/sqm, then you have to consider the COP... so 25kwh * 4 cop = 100kwh heat per sqm, at 200sqm you are at 20,000kwh.
For me it is 47kwh heat * 150sqm = 7000 kWh heat per year. That fits.
For Zaba, I think it was 10kWh/sqm? With a COP of 4.x, it is also close to my heat amount and the consumption data match quite well.
