Like for the ...Supply Air... and the ...Zone... output variables there are also a set of ...Outdoor Air... output variables for the ideal air loads system. You can use that to check the energy/rates for outdoor air.
OS leaves all the parameters in the IdealLoadsAirSystem object to defaults, and I don't believe you can change anything in the GUI, so you'll have to write a measure. The default for the outdoor air parameter is to not have any outdoor air which would explain the lack of difference you're seeing.
