ᐅ Controlled residential ventilation or demand-controlled ventilation – any experiences?

Can anyone tell me if a ventilation system with regulated air supply and humidity-controlled exhaust fans in the bathrooms can provide sufficient air exchange without manual ventilation?
Does a central mechanical ventilation with heat recovery (MVHR) system achieve a greater air exchange than the system mentioned above?
And is it possible to skip manual ventilation on cold days?
I’ve read in forums that nowadays well-insulated houses should not be built without mechanical ventilation.
Does a regulated air supply system also work effectively when shutters are closed?

...I simply receive my xxxx kWh of thermal energy delivered directly, and I don’t have the efficiency of a heating system that could still be positively influenced by controlled ventilation... Apart from controlled ventilation with heat recovery, it is definitely possible to optimize individual heat supply and achieve significant savings effects depending on the specific boundary conditions.

That’s already unfortunate due to the initial conditions! That’s a matter of perspective... I’m glad I don’t have to install a heat pump, which currently consumes increasingly expensive electricity (primary energy!), takes up space, and will eventually break down.
District heating is wonderfully simple in comparison ^^
Let’s wait and see, the future might put things into perspective As a heat pump owner at the moment, I’m actually more worried about the future ^^ I believe electricity prices have increased the most recently...
District heating prices probably won’t skyrocket here anytime soon (district heating isn’t the same everywhere; it depends on how the provider generates the heat).
And with a heat pump, I would never come close to the current cost per kWh anyway...
