[BLDG-SIM] Outside Air Temperature Controlled Exhaust

Assuming you are using DOE2 this approach may work.  You will have to test 
but define a packaged single zone system with the same flow rate and supply 
kW as your exhaust kW.  Do not define any exhaust in the zone.  Set the 
cooling capacity to a very low number.   Schedule the fans off but night 
cycle on any.  Set the heating set point very low and impose a process load 
in the zone to mimic the heat gain from the electrical equipment.  Set the 
cooling set point appropriately and this will cycle on the fan when the 
temperature gets too hot.  The best way to impose a process load without it 
showing up in BEPS is to add in the appropriate number of occupants and set 
the latent gain small and sensible high.

This may give you what you want.
