[Equest-users] defining the windows for natural ventilation

[John Aulbach]

So what then is infiltration in eQuest? THAT is separate of the outside air introduced into the HVAC.
 
There is the ability to perform rudimentary daylighting. It does ask for minimum footcandles in the data. So it must have SOME idea about natural illumination when the lighting controls step down.

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
