[EnergyPlus_Support] Re: airflow between-core perimeter zones

["JV Dirkes II" <jvd2pe@xxxxxxx>]

Dear Alper,

In my opinion, a very large hangar (i.e., multiple A320s) will
probably exhibit distinct zone characteristics, but small to mid-size
hangars will not.  In addition, the HVAC system will probably be
designed to favor comfort in the occupied area, which is often the
floor only; no one works near the walls or ceiling.

Finally, hangar door opening will completely destroy comfort and
setpoint control while open, making "zones" meaningless.

For these reasons, I recommend that you consider using a single zone
instead of multiple zones.
