From ASHRAE 90.1-2013 Appendix G:
"The HVAC system(s) in the baseline building design shall be of the type and description specified in Section G3.1.1, shall meet the general HVAC system requirements specified in Section G3.1.2, and shall meet any system-specific requirements in Section G3.1.3 that are applicable to the baseline HVAC system type(s)."
So no, you should not model a DOAS in the baseline building. You should use the appropriate system from Table G3.1.1-3.
