Dear All,

In a building with 6 underground parking storeys, air is exhausted
through a shaft and a single fan, while outside air is brought in
through natural flows on another shaft. This is achieved by jet fans
operating in each parking garage. The exhaust fan is variable speed
controlled by CO sensors in the parking areas.

Q1: How can I assign 6 underground zones to a single exhaust fan? As far
as I know, exhaust flows are assigned on a zone basis in eQuest?
Q2: How to model the speed variation of the exhaust fan? Any other way
other than using schedules?
Q3: Can eQuest model the airflows caused by jet fans? Or should I just
assign these as electric loads so that their electric consumption is
taken into account?

Thank you,
