Hello everyone,
I had my house calculated with a T8 36.5 with perlite filling and got the following result:
Annual primary energy demand qp [kWh/(m²a)] 53.79
Transmission heat loss Ht [W/(m²K)] 0.357
Therefore, no KFW70 either, since the transmission heat loss is not below 0.336.
Could that be the case, or with what means could I achieve a better value?
Info: Heating is water heat pump, no solar, no ventilation system
Thanks for your feedback!
