Easy way to do Jeplus Window,WWR parametric simulation using an file generated using openstudio?

My model has lot of windows (4 typical sizes) and is modelled using floorspace js embedded in openstudio. The idf file maps windows with vertex information format (GlobalGeometryRules, UpperLeftCorner, !- Starting Vertex Position!, refer to sample image window object in IDF) image description. Ihave around 60 windows in my building. so if i want to use jeplus for parametric simulation of these windows by changing height, or width. what is the easiest way to do this. I referred to the tutorial provided in youtube, but the IDF format given there is from design builder modelling and is shown only for one particular window; But for OS, floor space editor models it in a different way. I found some materials about EP macros, but I couldn't find any proper guide or tutorial. If there is an easy way to manipulate the windows and Shading (shading is also similar problem),. Please let me know.

It depends on the variations you want to test. For example, is it the overall WWR on different elevations or the dimensions of individual windows? What shading to include? Are those windows or local shading attached to the windows, or individual shading surfaces? And, how complex is the geometry of the building?

@Yi Zhang individual windows (4 different sizes.~50 in number ) modelled in FloorspaceJS editor) and then individual shading surfaces(using sketchup OS measure) . Model geometry is little bit complex. but only 4 typical windows are repeating at different rooms. Please refer to the image to see how the windows are coded in idf. please let me know how to do it. one way i have in mind is using different idf files for each WWR and copy pasting the fenestration components in the master jeplus IDF file. Please suggest me if there is any other way out.

If the geometry of the building is relatively simple and you don't mind the exact positions of the windows, you can simplify the model by using the "window" objects with multipliers to replace "FenestrationSurface:Detailed" objects, and then with jEPlus to manipulate the sizes. In your case, it is perhaps best to generate multiple IDF files, extract the relevant parts for the geometries, and then use EP-Macro's "##include" function to combine them into a jEPlus project. Here is some information about using EP-Macro with jEPlus:
