Building Code And High Rise Windows

A reader in the forums has a question about whether his bedroom window should be able to open or not:

I was wondering if someone knows about high rise condo building code regarding whether bedroom window can be open or not. I am looking at a unit where the bedroom has a few floor to ceiling windows but the windows can’t be open/close. The living room and kitchen have similar windows, half of them can be open/close and the other half can’t be open/close. I think the builder overlook the windows in the bedroom. There should be no reason why it can’t be open/close. Just wondering if there are any building code regarding this.

Can any of the architects/designers knowledgeable about this sort of thing help him out?
