Exceptions to G3.1.1:
(c) If the baseline HVAC system type is 5, 6, 7, or 8, use separate
single-zone systems conforming with the requirements
of System 3 or System 4 (depending on building
heat source) for any zones having special pressurization
relationships, cross-contamination requirements, or code required
minimum circulation rates.

I'm modeling a building that has baseline system 7. If I read this
correctly then all lab spaces will have their own system and that system
will conform to system 3 from table g3.1.1A. Is that correct? If so -
are all of my lab spaces going to be packaged single zone units? That
doesn't seem right - especially since lab spaces are more than 50% of
the building area in this case.

I'd appreciate anyone's help with this.
