Hello,
we have a semi-detached house of 150 sqm (1,615 sq ft) plus a basement, newly built by a developer.
I wanted to ask if it makes sense to retrofit a decentralized ventilation system?
The semi-detached house is KFW 55 standard, and ventilation is planned to be ensured by opening windows (this is the current plan).
Installing a central ventilation system is not possible; the decentralized one would have to be installed by us after handover.
Are there decentralized ventilation systems with built-in air conditioning (for the bedroom)?

Is it even allowed to make so many core drillings and install an air conditioning system in a KfW 55 house, thereby creating weak points in the insulation?Yes. Everything is taken into account. There are advantages in the calculation concerning controlled ventilation.
