[Bldg-sim] Baseline VAV OA vs Proposed DOAS OA

[韩星]

In my opinion, the baseline case OA should be equal to the proposed OA. OA required by 62.1 is only a basis for reference.

Hi all,

I'm looking for guidance on which number to use for my baseline OA when compared to the proposed system.

The proposed HVAC system is DOAS - FCUs. OA requirements according to ASHRAE 62.1 are 10,216 cfm. However, to satisfy exhaust requirements, the total system ventilation, i.e. OA as it's a DOAS, is 13,160 cfm.

Does the baseline OA need to equal 10,216 or 13,160 cfm?

Thanks
