You need to make sure your non-rated wall goes 6" above the ceiling. Not a huge deal, though!

Heights are off somewhere.

I tried this vignette also and got the same height results. Where are the heights off? I am testing in two days and want to make sure I understand the concept

I don't know where the error is. I do know that the relationship of the 2nd floor roof to the meeting room clg is incorrect.

I'll do it again this evening and see if I get a different result.

Second shot at finding any differences:

1st Floor
Top of Footing: -3'-0"
Ceiling: 8'-4"
Lights: 8"
Ducts: 24" (derived from a 32" x 24" max. duct size)
Joists: 28"

2nd Floor:
Ceiling: 8'-4"
Lights: 8"
Ducts: 24" (derived from a 32" x 24" max. duct size)
Joists: 20"
Parapet: 2'-8"

Meeting Room:
Ceiling: 26'-0"
Lights: 8"
Ducts: 12" (derived from a 32" x 12" max. duct size)
Joists: 28"
Parapet: 2'-8"

Question: Are the ceiling heights measured from the Top of Slab or the Grade Line at the first floor? I do see that in the NCARB example the Meeting Room ceiling is about centered on the 2nd Floor joists...
