<DIV><FONT face=Arial size=2>Dear Trnsys users,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I am not fully experienced in Trnsys so my
problem may be very simple to solve.</FONT></DIV>
<DIV><FONT face=Arial size=2>Trying to understand how to use the type 34
"Overhang" I made some tests and found strange results.</FONT></DIV>
<DIV><FONT face=Arial size=2>When Overhang and wingwall projections are set
to zero, beam radiation and ground radiation to receiver are
equal to same data from type 109. This is OK.</FONT></DIV>
<DIV><FONT face=Arial size=2>Sky diffuse is reduced a lot which does not
look normal</FONT> <FONT face=Arial size=2>to me.</FONT></DIV>
<DIV><FONT face=Arial size=2>Is there an explanation ?</FONT></DIV>
<DIV>
<DIV><FONT face=Arial size=2>Here attached is this simple
test</FONT></DIV></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>I also need some advice on the way to use the type
34 with the type 56.</FONT></DIV>
<DIV><FONT face=Arial size=2>Should I create in the building an orientation for
each overhang</FONT> <FONT face=Arial size=2>and connect the type 34
outputs to the corresponding inputs or should I only use the fraction of solar
shading from type 34 as the external shading factor of the window ?</FONT></DIV>
<DIV><FONT face=Arial size=2>I would appreciate an example on the way to connect
type 34 properly to type 56 </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Looking forward for your help</FONT></DIV>
