A window on a 1000 ft tall building is definitively not a fire escape. Large buildings like this, whether residential or commercial, have purpose built interior fire escape paths. I couldn't say whether the commercial version of this is 1:1 substitutable for the residential one, but come on, the fire plan for any modern building over ~10 floors does not rely on windows. Edit: Also, the fact that a non-operable window, or even a window too small for a person to fit through, will usually suffice to meet the bedroom/window requirement gives the lie to this "fire escape" idea. Edit 2: Correcting myself here, for residences without automatic sprinkler systems, two means of egress (could be a window or doorway to the outside, could be a doorway to another part of house) is a requirement for a bedroom in the International Residential Code. There is a separate requirement for certain levels of light (natural or artificial) that can be satisfied by an inoperable/small window, which is what I was thinking about. In any case, all the commercial buildings in question would have automatic sprinkler systems, these fire escape requirements just wouldn't apply.
