<DIV class=Section1><SPAN class=856033410-26102005><FONT face=Arial
size=2>Hello, </FONT></SPAN></DIV>
<DIV class=Section1><SPAN class=856033410-26102005><FONT face=Arial size=2>1. we
try to use for the same orientation shading mask with type 68 and overhang or
wingwall (type 34). </FONT></SPAN></DIV>
<DIV class=Section1><SPAN class=856033410-26102005><FONT face=Arial size=2>Which
one should come first after radiation processing? : </FONT></SPAN></DIV>
<DIV class=Section1><SPAN class=856033410-26102005><FONT face=Arial size=2>-in
type 34, the horizontal diffuse and total radiations are inputs, so is the beam
radiation on surface. </FONT></SPAN></DIV>
<DIV class=Section1><SPAN class=856033410-26102005><FONT face=Arial
size=2>-upstream component mode equals 1 signifies the view factor is
already taken into account for the diffuse radiation with type 68 .
</FONT></SPAN></DIV>
<DIV class=Section1><SPAN class=856033410-26102005><FONT face=Arial size=2>how
can it take into account the view factor for shaded diffuse radiation on
horizontal since this is not an output of type 68 ,.... but still an input
of type 34. I assume it can't neither be through the shaded beam on
surface...</FONT></SPAN></DIV>
<DIV class=Section1><SPAN class=856033410-26102005><FONT face=Arial
size=2></FONT></SPAN> </DIV>
<DIV class=Section1><SPAN class=856033410-26102005><FONT face=Arial
size=2>Furthermore, we encountered inconsistent results using type 34 after type
68 : more sun on the window than with type 34 only. Using type 68 after type 34
seems to give more consistent results but we are still not sure they are correct
since it is not the right order. Could you give an explanation of
this problem? </FONT></SPAN></DIV>

<DIV class=Section1><SPAN class=856033410-26102005><FONT face=Arial size=2>2.
Else, another problem :</FONT></SPAN></DIV>
<DIV class=Section1><SPAN class=856033410-26102005><FONT face=Arial size=2>when
the .bui file and the .tpf file are located in the same folder, we sometimes get
an error message. Changing the location of the bui file in another folder solves
the problem... has anybody ever encountered this bug? </FONT></SPAN></DIV>

<DIV class=Section1><SPAN class=856033410-26102005><FONT face=Arial
size=2>Thanks in advance for any explanation (especially for the first
point!)</FONT></SPAN></DIV></BODY></HTML>
