Louvers on Solid Surface

I have a case of Southern aluminum louvers that do cover the entire wall, and I'am modelling the basecase without these louvers. I need to know if it's permissible to gain credits by shading both; southern windows and southern wall together? I need also a suggested software to perform this simulation since that I'am using eQuest and it provides louvers only for glazed and not opaque surfaces as far as I know thanks

The basecase is modeled without shading so you can take the credit. However, I would think there would be very little effect from shading an opaque wall that is even moderately insulated. I obviously do not know enough about the project to say for sure so maybe it is worth evaluating. I am not sure of a software that does so but I would start with Energy Plus, maybe IES-VE?

If the louvers shading effect is 100 % you can modell them as north facing in the proposed model and regular orientation in the base line.
