Here's where you're going, Ron, was there and won in a variance- your mileage may vary:
IBC allows an exemption for egress distance with heat and smoke vents for exceeding 250'; I argued somehow successfully that we could follow the code like this: Design building with heat and smoke vents to allow exceeding egress distance Then replace standard sprinklers with ESFR and the need for the vents disappears- BUT the egress distance could stay. It helped an architect chaired the variance committee. Ironically, my customer's competitor was in front of us with same request for another big box, and their "expert" was tied up in traffic. So I testified, at my customer's request, for their competitor since we needed them to win their variance. Then stood up for my customer and said "what I just said" and that was enough.

And if we use ESFR's throughout the entire building are they required? I read that they are (2006 IBC 910) but I'm not sure if there are exceptions elsewhere?
