Dear M. Waseemahmad,
In “Zone Ventilation: Wind and Stack Open Area”, for each openning window there will be data entry into an object field.
In your model, the effective angle to north window will be set to 0, while the southern window will be set to 180. To “height difference” inputs, look this schematic figure from ASHRAE Fundamentals, in chapter 16:
Windows with different heights, or juxtaposed to one another in the same thermal zone will have different values of “height difference” for each one.
Best regards,
