What @Dinosaver said, regarding EnergyPlus compatibility.
I'm not 100% clear on what you are trying to calculate here, either. I'm ASSuming you want vertical illuminance on the facade(s), or just inside the space? You could use Radiance in OpenStudio for this, as the illuminance maps can be translated about any axis you want. The problem is that the OS-Radiance measure calculates typical daylight metrics like DA/sDA/UDI and these are based on horizontal illuminance, with a plan-view spatial component. So the metrics will be invalid.
If all you want is vertical illuminance in section, I recommend using a series of glare sensors, aimed at the facade(s) of interest. These will give you an annual schedule of vertical illuminance at each point; you would have to collate this data and visualize manually, but the data is written out, e.g. glare.json in the run/[radiance_measure]/radiance/output directory.
