Matt, I will ask the code people here in a little while, but my 1st thought is- was any kind of life safety analysis done? I think some manual vents would be required, but auto vents would be based on egress lengths.

I looked around in the IFC/IBC/IEBC books, but I could not find anything that would exempt the vents and curtains. Does anyone recall any way to avoid them (other than ESFR)?
