Ventilation of the insulated attic

For our attic (90° / approx. 30m³ / insulated / uninhabited / unheated / without windows) we need suitable ventilation. Can you recommend something suitable for us?

Ventilation system that is also used for the rest of the house.

Thank you very much,
yes sure, however the Nibe air heat pump is located downstairs in the utility room. To lay the pipe, the entire duct would have to be opened up to the roof apex. I want to avoid that.

Are there any other possibilities?

Regards

Decentralized fan with humidity sensor, if necessary heat exchanger and supply/exhaust air via the roof. The measure must of course be coordinated with the ventilation concept according to DIN 1946-6 for the house.

Can't two tile roof ventilators at opposite ends be sufficient?

Sure, but why include the attic in the thermal envelope at all? Now you heat the place including the attic and then lose the heat through the ventilated roof tiles again.
