Hello,
I consider that very bold, because in my opinion, it would not have sufficed without a ventilation system anyway.
In my opinion, that "improvement" of the windows will not work either...
It also depends on when you want to submit the building application. From January 1st, 2016, the reference house corresponds to today’s KfW 70 efficiency house standard. However, you can still apply for the KfW 70 subsidies until the end of March 2016. It is absolutely necessary that the online application is submitted to KfW by that date!
Well, that’s how it is with beliefs...
Mathematically, the building envelope and technology are considered – here the geographical location of the building project also plays a significant role; in total, the possible funding standard only emerges from this ;)

A few months ago we had an initial conversation with a construction supervisor/developer. We had jointly discussed KfW70 (because of the subsidy) with a gas boiler and solar thermal. Clearly no problem, we were told.
I consider that very bold, because in my opinion, it would not have sufficed without a ventilation system anyway.
Yesterday, the statement came from the supervising architect who is also officially listed as a KfW consultant (see KfW homepage) that their program/calculator outputs that our desired KfW70 house would only be feasible with a heat pump. If we still want a gas boiler with solar thermal, we would have to "improve" something at the windows (something with noble gas filling).

I always thought a KfW70 house consumes only 70% of the energy of a reference house, which in my opinion reflects in the insulation. Are the heating systems also compared with regard to their specific energy consumption?
