NC-2009 EAp2: Minimum Energy Performance
Can someone help me with exception "b" of mandatory section 6.4.3.9 in 90.1.
What is meant by the following:
b. multiple zone systems without DDC of individual zones communicating with a central control panel.
Must my client install DCV in an auditorium that meets all of the requirements of section 6.4.3.9 if the auditorium is fed by a multizone VAV system with DDC control?
What damper would the DCV control?

It sounds like it should be installed. If you have DDC is sounds like you do not meet exception b.
Hard to design your system for you. Typically a space that that would have its own system so I do not know enough about your systems to offer any advice.
