We did use LoopDa with good result and it is free at :

We try Energy+ but it is hard to use and there is a lot of parameter to
adjust.<br><br>

EnergyPlus has an module called airflow network, that works wich
pressure nodes and ventillation pathways. It`s not a CFD but for the
purpose you will use I think its even more appropriated than a CFD
software. You can learn more about at:

<dd>Hi Mimta, <br>
<dd> <br>
<dd>For natural ventilation. I will recommend IES VE. It has tow modules,
MacroFlo and MicroFlo (CFD), which are able to address your specific
requirements at different scales. I've used both modules quite often to
solve particular ventilation (both natural and mechanical ventilation)
issues. TAS and Energy Plus may be able to do the same thing but I've
never used them for ventilation analysis. <br>

<dd>Hi,<br><br>
<dd>We use eQuest for our energy models. We are now faced with a project
where we would like to know the effect of stack-effect natural
ventilation in a 5 storey building and how it can help us undersize the
mechanical equipment, especially due to night cooling of the concrete
structure. Further, we would like to use the same modelling for LEED
compliance. eQuest seems insufficient for this. What is the recommended
practice for this?<br><br>
<dd>Thanks,<br><br>
