I didn’t find it. Maybe it would be interesting to collect anonymized data on what the actual energy consumption of the properties ends up being.
My own data situation is still a bit thin because we are only moving in properly next month, but the house has already been heated cozily warm to speed up various drying processes. At first glance, it looks like it will be a close call with the KfW 70 limits. The thermal bridge surcharges (0.1 W/m²/K) were therefore justified.
Suggestion for structure:
Type:
Single-family house, KfW70 renovated
Envelope surface according to Energy Saving Ordinance
356
average U-value of the envelope surface
0.299
usable area [m²]
131
standard temperature [°C]
20
bathroom temperature [°C]
22
heating energy demand [kWh/a]
7000
net heating costs [€]
512
heating type
heat pump, brine-water
Note
Extrapolation of standard annual consumption from 3 winter months!
