ᐅ User-independent ventilation system in bathroom / restroom – recommended or not?

kgeislerHello,
I am building a turnkey house and have now been presented with the following choice by the housing company:
"According to current standards and applicable technical regulations, we are required to ensure a user-independent minimum ventilation for moisture protection. For this purpose, individual fans are planned for both the bathroom and the toilet. The single-room fans are installed as so-called 'continuous ventilation fans.' This means that both fans continuously extract 30 m³ of air per hour (about 18 cubic feet per minute) and vent it outside. The air being extracted is replaced by inflow through window frame vents into the rooms. These vents are mounted invisibly (when the window is closed) on the window frame."
The fan can be switched to 60 m³ of air extraction per hour (about 35 cubic feet per minute) via a switch, and there will be a humidity sensor that automatically increases the ventilation when the moisture level in the bathroom rises.
I am having a KfW55 energy efficiency standard house built according to the 2009 Energy Saving Ordinance.
The bathroom has a window, but the toilet does not.
The question now is: do I want the user-independent continuous ventilation as described above, or would I rather have it completely off until I switch it on manually?
My tendency is not to want the continuous ventilation, but I have no idea how loud this continuous operation actually is.
Has anyone had experience with this and would choose either way again or not?
Or are there any opinions and tips?
I would be very grateful!

Therefore, individual exhaust fans are planned for both the bathroom and the toilet. Window ventilation is also considered a ventilation measure (ventilation technical measure, VTM) according to DIN 1946-6 ;-) For windowless rooms such as toilets, the respective regional building codes usually apply. In most cases, at least an exhaust system is mandatory. Intermittent operation is usually more advisable than continuous operation.
Best regards
But what about noise levels?
Of course, I want the ventilation system, but the question is whether it should operate independently of user input or only be controlled via the switch?
And should I also set it to operate independently of user input in the bathroom with a window?
