NC-2009 IEQp1:Minimum IAQ Performance

single zone or multi-zone calculation?

I have a project, which have two types of system: 1. OA system offering the fresh air to each room, and each room has an individual fan coil unit . 2. OA system offering the fresh air through chilled beams to each room. Should I verify the ventilation by 62MZ calculator or single zone as IEQp1-A2 table? I appreciate any comments for this.

If the OA system is variable volume, then you should you the MZcalc. If not, you can treat each one as a separate zone receiving a set amount of OA.

It is VAV for OA system. In MZcalc, should I include fan coil supply air (or chilled beam induced air) and outdoor air into the design supply air? It says primary plus local recirculated, just want to make sure. Thank you!
