Simulating varying parameters

edit

Dear all, I have some issues modelling with OS and E+, I want to ask about how to vary shading coefficient (SC), window to wall ratio and different orientation in open studio/E+. I Know how to create a building in OS with different WWR and safe as separate files but I don't know how to do that of shading coefficient in either programme. Regarding orientation, I find the four orientation in energy plus but not in open studion (that is N,S,E,W) but I need to simulate 8 different orientation in my study (N, NE, S, SW, E, SE,W & NW)and I do not not how to go about this. Again I would like to know if there is a better way than building 7/8 different model with different WWR in OS, I guess there should be.

Thank you everyone olutobi
