well… read the Grasshopper notes and found the answer:

_We are adding two window groups for_  
_this study. The skylight is its own window group_  
_which is not dynamic but we’re interested_  
_to study its contribution separately._  
_South window is the other window group_  
_which has two states: 1. clear, 2. diffuse50_

_ **Ensure that window groups are facing outwards.** _  
_ **Honeybee flips the surfaces for view** _  
_ **matrix calculation internally.** _

_Window groups are under ./scene/wgroup_
