Yep. My little apartment (400m²) in a low-rise in Canada, built just five years ago, has no in-unit ventilation whatsoever. If I want a cross-breeze (and I always want a cross-breeze), I have to open the outside windows and the door to the hallway, and let a ton of dust and pollen flow into the unit from outside. I have no idea who thought building an apartment building today like this made sense, but it seems to be a common perspective.
