[Equest-users] defining the windows for natural ventilation

[Daniel Knapp]

Hi Noa,

My understanding is that eQuest does not calculate natural ventilation at all.  The program is not designed to support calculations of the movement of air between zones.  The outdoor air flow in the HVAC window is outdoor air introduced by the mechanical system and not through windows.  I think you would be better off looking to another tool (maybe EnergyPlus/OpenStudio?) that explicitly supports these calculations.

All the best,
Dan
