If you have photovoltaics, all good, but without it you move further and further away from low energy etc...
Building a KfW 40 house, thermal insulation to the power of 10 so that nothing is lost in winter and then blasting out the energy in summer with the air conditioning, I think that doesn't fit together
We don't have KFW nonsense
