I'm working on a project that consists of a large warehouse, drive-in bays and a narcotics storage. Currently I have separate ventilation and exhaust units for each space. Indirect heating and ventilation for the warehouse and narcotics storage and direct heating for the bays. I would like to persue this credir but I could not find in the LEED Guide whetther or not I must include MERV 13 filters for both direct and indirect units above. The warehouse and narcotics storage room are considered regularly occupied spaces.

Is there anyone with the similar experience that can provide help on this?
Really apreciste your help!!!
Thank you!
