This is the paradox of modern homes: we try to seal a max (= euros !!) ... then we put a big hole in the air = a VMC! I always found it funny ...
Some materials allow to do without ventilation. This is the case of cellular concrete which naturally pumps the moisture outwards.
My garage, which has no finishing coating on the cellular concrete, can go down to 30-35% moisture ... Top to dry wood!
I dry my laundry indoors all year round without any worry of moisture or condensation on the walls. Well I live alone ... not the same as an average family of 4 people ...
