Well the Army installed great heavy-duty double paned windows that you could totally open and close. However, they were kind of bulky and ugly, so many people (especially on the North side with a view of the Sound), have replaced them with big unopenable picture windows. Whittier is really not THAT cold most of the time.
Was it a bit stifling, even with air-con/ventilation, not being able to open windows for fresh air? I don't think I could get used to that!
Most houses retained an openable window or two. Every apartment had a big vent with a fan.
