Air Change per Hour due to wind driven cross ventilation

Also, take a look at the EP outputs I listed in this post:

Air flow volume output from HB Read results

@deepthi.ravi, @ElzineBraasch You can usually find most outputs by searching the EP Input/Output reference, and using the HB components for searching and reading custom EP results. From the wind and stack ventilation section, you can get the ventilation flow rate with the following output terms: Zone Ventilation Current Density Volume Flow Rate Zone Ventilation Standard Density Volume Flow Rate Zone Ventilation Air Change Rate You’ll want the “Current Density” flow rate, if you want the flo…

I was able to reproduce the ACH from those outputs:
