ᐅ Decentralized Exhaust Ventilation System SCHIEDEL AERA COMFORT

We are planning to build a single-family house (details below) and intend to install a decentralized exhaust ventilation system Schiedel Aera Comfort. We have already been in contact with three homeowners who are very satisfied with it. We do not want heat recovery or fresh air supplied via ductwork inside the house; instead, we prefer fresh air delivered directly into each room. Is there any experience with such systems? An important question for us: We will probably achieve KfW 70, but would such a system also be acceptable if we aimed for KfW 55? You can see our building project below. Where would we need to "upgrade" or is this only possible with a ventilation system with heat recovery (which we both firmly do not want, as mentioned already, it’s a matter of preference)... thank you for your answers!
