Hello,
the requirements for KfW40+ are - simplified - as follows:
- KfW40
+ Installation of a photovoltaic system
+ Installation of a stationary power storage system
+ Installation of a controlled residential ventilation system
But what if you are currently at KfW55 (without controlled residential ventilation) and, besides the photovoltaic system (which is going to be installed anyway), only a controlled residential ventilation system is needed to reach KfW40?
Is it necessary for KfW40+ that the KfW40 standard is already met or could be met without measures from the Plus package (photovoltaics, storage, controlled residential ventilation)?
Could the KfW possibly be a bit strict in this regard?
Otherwise, for me, practically only the controlled residential ventilation system + storage would be necessary to jump directly from KfW55 to KfW40+.
