Parametric shaders from Grass to Ecotect

Hi guys,

everyone knows some tutorials/examples/plugins about these two problems:

1. parametric creation of light shaders on windows.

2. Daylight analysis of a room into Ecotect and creation of graph in order to choose the best solution.

I'd like to combine these elements in a topic for my final thesis, since i'm a newbie into Grasshopper and Ecotect, i'd like some help.

Thx in advance :)
