Are you sure about that?
How about natural lighting? Does it calculate it?

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
