<P><FONT SIZE=2>Hello,<BR>
<BR>
In order to calculate the shading of a nearby building in combination with the effects of an overhang we used the type 67 and type 34 in simulation studio.<BR>
We made all the connections discribed in: <A HREF="http://sel.me.wisc.edu/trnsys/downloads/tutorials_and_examples/connecting34_67.pdf">http://sel.me.wisc.edu/trnsys/downloads/tutorials_and_examples/connecting34_67.pdf</A><BR>
However we want to use the solar shading fraction on the reciever to connect with the building file type 56 as an external shading factor on a window.<BR>
For this, we always get a negative number.<BR>
<BR>
In attachments you will find our .bui, .tpf and type 67 external file<BR>
