[TRNSYS-users] About Shading masks (type 67)

[Fabien Morice <fabien.morice@yahoo.fr>]

Dear TRNSYS users, I have a question for you :

 

I try to use the type 67 with the type 56a (Multizone Building) ;

but I don't know which output I must connect with the type 56a.

 

 I tryed to use an equation to have the Fraction of Solar Shading (FSS)

(same the type 34 gives):

FSS=1-(Shaded total radiation for surface/Total radiation for surface)

with Shaded total radiation for surface given by the type 67

and Total radiation for surface given by the type 109.

But the FFScalculated is not between 0 and 1 !

 

Could you help me ?
