[Equest-users] Query regarding PDEC ( Passive cooling ) simulation in eQuest

[Design Builder USA]

You may wish to explore the free trial of Design Builder, as it has CFD,
natural ventilation and evaporate cooling.
Tho I am not sure if it can be used for your passive cooling requirement or
not..

Best of luck
