Using DesignSpecification:OutdoorAir with Zone Multipliers [closed]

Hi Unmet Hours community,

This question pertains to EnergyPlus, version 9.6, but likely other versions.

I have noticed that in the DoE Commercial Reference Building Models, that DesignSpecification:OutdoorAir (DSOA) objects which are referenced by zones with multipliers usually use the "Outdoor Air per Zone", while most others use "Outdoor air per Zone Floor Area". This value is also seen to be much larger (ref: Large Hotel guestroom zones with multipliers vs. zones without).

After a deep look into the IOR, I have not found the answer: Does the zone sizing algorithm take zone multipliers into account when calculating outdoor air required by DSOAs? And how does this answer change depending on the method of DSOA input?

Thanks in advance! David
