I wasn't talking about leaking windows. You can't seal a house up and think it's going to be a nice place to live. You need a way for the house to breath. Which is exactly what you've said.
Sorry, I thought you were agreeing with the person you were replying to. Like adestefan says, I consider 'breathing' (like 'organic ventilation') a euphemism for 'crappy air control'. But if we use 'breathing' as 'well-ventilated, in a controlled way', then I guess we agree.
