Thanks for your reply. I also found these examples from page 4-127 of the 2016 Nonresidential compliance manual and this seems to relate to my question. This was in the section regarding space-conditioning system alterations.

It seems that you are correct and that it isn’t as simple as installing new VAV boxes, we must also check the existing VAV system and make adjustments to ventilation as needed.
