Can Fire Station Doors be considered windows

Hi Michael, Just so I am clear: are you talking about using the operable fire house doors as operable windows for EQc2 or EQc6.1 or both? I believe in either case you'd need to see if the fire truck doors meet the technical requirements of ASHRAE 62.1-2004, paragraph 5.1., Natural Ventilation. I'd see if ASHRAE 62.1-2004 has a definition of an operable window or something of that nature. On a sort-of unrelated note, I've been able to call fire truck doors as windows for EQc8 before by stating that they were open at a high frequency with a written letter from the owner of the fire house. I think it's another case where the situation may or may not be accepted by your reviewer.
