Re: [TRNSYS-users] Overhang and wingwall shading

["Arie Kalkman" <a.kalkman@chri.nl>]

Dear Edward,

Concerning your first question, I think Type 34 calculates the shading of a
'receiver'. This can be either a wall or a window, or something else,
depending on your model. Usually, with e.g. 50% window in a well insulated
wall, the window-related effect will be the largest by far.   
It is possible that the shading of the wall becomes important, e.g. when the
wall has a low thermal resistance. It may be necessary to separate both
contributions, by labeling the wall and the window e.g. South1 and South2,
and calculating the shading of both areas by two different Type34's.

Regards, Arie.

Onderwerp: Re: [TRNSYS-users] Overhang and wingwall shading

Dear All,
 
I read the discussions on the above subject in the links below:

http://sel.me.wisc.edu/trnsys/mailinglist/archive2003/msg00009.html
http://sel.me.wisc.edu/trnsys/mailinglist/archive2003/msg00292.html

Can anyone help me with the following questions:
1. Does TYPE 34 handle only windows ? How about the wall surrounding the
window ? Shouldn't an overhang or wingwall affect the wall and windows
in terms of beam radiation it receives ?

2. In TRNSYS 16, should I still need to separate the modelling of the
windows affected by overhang from the wall model ?

Regards
