I'm looking for a fresh air requirement for an "assembly" building (sled manufacturing - mostly woodworking). I can't find a reference to this type of building in the IMC or ASHRAE. I would guess that it falls somewhere between a warehouse and a parking garage, but the difference in requirements between these two spaces is quite large (0.05 cfm/sq ft compared to 1.5 cfm/sq ft). Can someone please point me in the right direction to find this type of information? Thanks!

Use minimum 20 CFM/person or .05 CFM/SF + sum of all exhaust for makeup. The higher requirement for garage is for dilution of engine exhaust CO Co2 etc.
