[EnergyPlus_Support] visible absorptance and reflectance

["dademarino" <marino-tesista@xxxxxxxxxxxxxx>]

Dear Users of EnergyPlus,

I am making a daylighting analysis of a building without thermal 
simulation. The color of the internal materials of the walls is 
important for this analysis. In particular the visible absorptance 
field in the Material input syntax is important for a daylighting 
analysis such as written in "InputOutput Reference". 
I have given one look to "DataSets" about visible absorptance of 
materials.In "DataSets" the color of the materials is not specified.
Can someone supply me values of the visible absorptance in relation to 
the color of materials of the walls?

An other relative question to my analysis is:
Can someone supply me values of the visible reflectance about trees and 
shading detached surfaces? 

Best Regards,

Marino Davide.
