how to estimate air change rate under natural ventilation mode

May I ask how to calculate air change rate under natural ventilation mode in OpenStudio, if a fixed air flow rate is not specified for the building?

I asked this because I saw in the following video that DesignBuilder has an option to switch between "scheduled ac/h" and "calculated ac/h" to estimate intensity of natural ventilation: https://www.youtube.com/watch?v=NS9ix...

So, can we do this also in OpenStudio?

Thanks!

Natural ventilation is not yet supported in OpenStudio, however you might want to look into the EnergyPlus object named ZoneVentilationDesignFlowRate. This object is isolated well enough from other objects that it would be a good candidate for an EnergyPlus Measure in OpenStudio.

Is there any update on this topic? It looks like that Openstudio 2.7.0, the one I'm using, has the natural ventilation feature. Would be good to learn more about it. Cheers
