Gas and electricity consumption in new construction

Interesting to hear about that. I thought it was normal. I have now addressed it to the manufacturer and they are looking into the matter. Apparently, about 500 kWh is normal.

Thank you for the tip.

4 persons - 125m² - 23°C
Gas: 11.036kWh

Whereas the ventilation alone is already between 900 and 1500 kWh.

The value is a bit unrealistic. Depending on the ventilation unit, the power consumption is on average about 60-90 watts.

Had we already

According to information, the manufacturer's specifications rarely take into account the individual piping network including all pressure losses.
