Maybe I'm missing something. Why not call panel construction beam and girder if the beams are less than 7.5 ft apart? The only difference between the two definitions is that panel has to form pockets to collect heat and beam and girder doesn't, plus beam and girder can still have steel decking on top of the beams and there is no 300 sqft limit.

Since the allowance to treat the panel pocket as obstructed construction and place the sprinklers further down from the ceiling is based on capturing heat, having all those open channels seemed counter- productive. Thus the clarification with the wording "including the interface at the roof". Granted the "roof" is on the outside but it's used synonymously with ceiling as in 3.9.16 Roof Height.
