In most buildings, ventilating a room while preserving temp in winter involves heating the incoming air. So there's a sweet spot between heating and ventilating when it comes to avoiding humidity.

that's why you don't ventilate by opening windows wide open but with purpose built fans with a heat recovery device.

  That's the sense of the "most buildings" caveat: double flow ventilation systems are still uncommon in Europe, especially for housing.
