It appears that ASHRAE completely ignored that fact, or only intended these vestibules in A, B, E, I, or M occupancies. I completely understand their purpose in an occupancy like that, but dispute it in an F or S occupancy where large doors are major sources of heat-loss when open.
I was told that you need to take the door opening and closing into the envelope design. I have no idea how to do that? Any thoughts or suggestions? I told the official that if the doors were open, it would be impossible to ever get a building to work. I was told "We're not designers.........that's your issue to deal with." That sounds snotty, but she was kind when she said it.
How do I deal with this? Does anybody have any insight to how ASHRAE thinks about this? Anybody have any contacts at ASHRAE that I could get in touch with?
