If you make your windows about twelve inches wide intruders cannot fit threw the broken glass hole lift behind.
Make the windows non opening and use sections of the wall that open to allow for air movement one at the extreme top of the building and the other at the extreme bottom on the opposite side of the building and the air flow will cool the occupants.
Windows and shutters set up this way will allow for a chimney effect, screens can be placed over the shutter openings and do not restrict the view.
This leaves the windows for looking out of. Then there is the added bonus of having to make only one frame to hold the window glass not three, first hole to hold the say metal frame the metal frame to hold the sliding frame to hold the window.
