If you want to do that out of HB tools, you should use some small scripts (in python or … ) with csv-readers, plus have a better understanding of the generated ill files and the folder structure (https://github.com/ladybug-tools/honeybee/wiki/Daylighting-simulation-scene-folder-structure). @mostapha Unfortunately the link doesn’t work …
Basically for each window group that you defined, you have one ill file for clear state (…default.ill) and one (or more) for your shading state(s). Check how you named them in your gh. (start with a simple model… )
Forget the files below (you don’t need them for post processing):
If you take a look into the individual ill file, you see part of the header lines as below:
Applied 1x3 matrix transform
The NROWS shows the number of sensor points and NCOLS shows the TIME (hour of year). So based on your time (e.g. HOY=400) if you pick the value form 400th column and 1st line, this is the contribution of that specific window(+shade) into the illumance value (lx) on the first sensor point.
If your sensor point gets light from 2 windows (or more), you should pick the values correctly, and just add them up to get the total illuminance on that point, on that time, for that specific shading state/combination.
