How to optimize WWR for a mid-rise building ?

edit

not sure i understand what you are asking exactly. in a typical energyplus run you can find the WWR in the html file.

for Jeplus, if you are using it to setup multiple variations of WWR and run accordingly, you will need to manually create the alternative geometries and use an if statement to run each and report accordingly.

a quick way to do the alterations to the geometry is to use openstudio native scripts to apply a ratio to windows in your model.
