Hello,
Hopefully a mild climate location. Pay attention to precise planning/dimensioning => manufacturer/device selection!...So we are also currently working on a Kfw 70 house. We have no solar, no photovoltaics. But an air-water heat pump ...
Basically, it is advantageous that AW and AF do not differ too much in terms of U-value, so that the surface temperatures do not differ too much (cold air feeling, especially with very large window areas). On the other hand, the windows are usually the "weak point" with regard to condensation. That is not so bad! An unfavorable combination is poorly or non-insulated exterior walls with very well insulated windows. Best regards....And you have to be careful that the insulation thickness matches the windows, so that they do not sweat.
