I'm trying to model a warehouse for LEED v3 that will have large trucks
driving in and out of it. The building will be supplied with the ASHRAE
62 min OA via a DOAS. Additionally, the building has large fans and
vents that open when sensors detect high CO2 and/or products of
combustion from the trucks. The amount of OA they bring in is far larger
than the ASHRAE min. The owner estimates trucks will be in the building
with engines one 6 hours per week.

Is there any way to model two separate outside airflows with different
schedules? Any recommendations on what to do for baseline vs. proposed
models? Can I take credit for the DCV sensors on the "process" outside air?
