[Equest-users] 90.1 G3.1.1 and Manufacturing Facilities

I am modeling a large, conditioned manufacturing facility with attached offices. The baseline building is modeled as System 8, “VAV with PFP Boxes.” The proposed building uses constant volume RTUs. From a design perceptive, I see how a VAV system makes sense for a standard office building, but using VAV for a large and tall manufacturing space does not seem appropriate. Does anyone have any experience using the exceptions in Section G3.1.1 to allow for a constant volume system (similar to Sys 4) in a manufacturing space?
The manufacturing area will have higher process and occupancy loads than the offices, but is the predominant condition when compared to the office spaces. I did see some 90.1 interpretations that indicate that only the smaller spaces (<25,000 sqft) would be eligible for the G3.1.1 exceptions, but wanted to see if anybody had a different experience arguing it to LEED.
