[TRNSYS-users] questions about shadings

[Laia Cases - iMat]

Hi trnsys users,

I have taken a look to the tutorial about how to make a shading mask and 
a shading by wingwall.
1. What is the reason to consider the total diffuse (sky amd ground) for 
the far away objects but not if you are cosidering only the wingwalls? 
2.What does it really mean the parameter "upstream component mode"? what 
happens when you have linked a shading mask and a shading wingwall, and 
then you don't want consider the effect of shading mask, if you set 
parameter to 0, does it take it into acconut only shading wingwall 
automatically?

3. "View  fac. to sky", when defining the walls of the building, does it 
affect during the day and the night?

thanks in advance

Laia
