algorithmic modeling for Rhino

I am trying to model a self-shaded freeform facade using Ladybug. The resulted mesh that I obtain from the 'shade' output from 'shadowRange' component looks incorrect or opposite. The meshes which should be sun-exposed are 'sun-shaded' in my model. Attached is the file. Need help to fix it. I would appreciate if somewone explain me the logic/algorithm to locate the 'self-shaded' meshes. Thanks.

Iasef, I tried to open your file but it was immediately trying to download an EPW file and hung Rhino. If you set the Open EPW file or Download EPW file with a Boolean Toggle set to False, then the file will open without demanding this action.  You should also set all "Run it" to False for the same reason.
