Re: [EnergyPlus_Support] Looking for Stack Ventilation Example

[Frederick Winkelmann <FCWinkelmann@xxxxxxx>]

Hannah,

COMIS, and its implementation in EnergyPlus, can simulate your case as long as the openings at the top and bottom of the
atrium are vertical. You can model the openings as windows or doors. The openings can also be controlled according to an
inside-air-temperature ventilation set point and inside/outside temperature difference (see EnergyPlus IO Reference Manual).
You can, in fact, have multiple openings at the bottom, at the top, and even in between if you want. We do not have an
EnergyPlus example of your particular case, but perhaps other EnergyPlus users can help.

I'm not familiar with PASSPORT-AIR  or AIOLOS.
