Hi
I am new at grasshopper and honeybee/ladybug 
I have a problem with my illuminance file - the lux values are way too high. Could it be a problem with my assigned materials? I have previously had problems with materials - is it possible that I am missing a material database on my computer?
Any help is highly appreciated - many thanks!

Sara,
See attached.
I marked the issues you had.
Basically your test surface normal is pointing outside. As a result the grid was out of the space. I flipped in the GH.
You were missing the LB_LB and GH_GH components. The glass material was assigned to the walls/floor/ceiling instead of the windows.
