Re: overhang

[Michaël Kummert <kummert@xxxxxxxxxxxxx>]

Dear Isabelle,

just a short addition to Helmi's answer: since the TRNSYS 15.3.00 
release, Type34 includes a new output which you can directly connect to 
Type 56.It is output 11, "fraction of solar shading". You can take a 
look at a previous discussion for more details:
http://sel.me.wisc.edu/trnsys/mailinglist/archive2003/msg00007.html
(keeping in mind that you don't need the equation anymore if you are 
using TRNSYS 15.3.00)

Regards,
Michaël
