I am modeling a building that directs all building exhaust through an energy recovery ventilator, including bathroom exhaust. Can I take credit in the baseline for the ERV exhaust fan since it handles the independent, code-required bathroom exhaust? Or can I only take credit for the portion of the ERV exhaust that serves the bathroom?

Model the proposed as designed. Model the baseline fans according to appendix G. If energy recovery is required in the baseline according to G3.1.2.10 then you include it, if not then it is not modeled in the baseline.
