Hello,
One Air Handling Unit serves multiple zones (for example : one office room 100sqf, one plant room 100sqf, one storage 100sqf). Using option 1/path 2, during flush out and building occupancy, we plan to provide at a minimum 0.3 cfm/sqf of outdoor air (ie 300 sq x 0.3 = 90 cfm at the AHU).
However, this total amount of outdoor air will not be shared fairly between spaces : for example 50 cfm in office space and 20/20 in storage and plant rooms.
Does it comply with LEED requirements ?
Thanks for your comments

Auriele, this is a little bit of a gray area in the LEED requirements, about whether the flush-out volume needs to be compliant for every square foot of space. However, in a case like yours where it's very clear that certain areas won't receive the specified volume, I would supplement it with fans, etc.
