Hello everyone,
We are currently building a new energy-efficient house and are considering whether to have a core drill hole installed for kitchen exhaust ventilation. Our chosen range hood can operate either as exhaust or recirculation. The project manager recommended using the hood in recirculation mode with activated carbon filters. However, the kitchen installer advises exhaust mode, as only this option supposedly eliminates odors and similar issues effectively.
We are now conflicted and thinking about having the core drill hole made but initially not using it, operating the hood in recirculation mode instead. The core drill hole would be fitted with an external grille cover and internally closed off with a cap. If needed later, we could connect the hood with a duct and have the setup ready for that.
From your point of view, is this a sensible approach, or am I missing something? What would you recommend? Should we have the core drill hole made or rather not?
Thanks in advance and best regards

Correct, or is something still missing? Possibly a cladding for the duct. Otherwise, the pipes will be visible. Or electrical wiring if it is to be operated electrically.

For me, a "low-energy house" means "everything that generates heat should stay inside" — so then exhaust air?
Is that even "allowed" with the appropriate subsidy / grant?
