<DIV dir=ltr><FONT face=Arial color=#000000 size=2>The easiest way to do this is
to use a single window on each wall. Calculate the percentage of window
area that is actually frame and then adjust the frame-width to account for the
increase. You may end up with a window frame width that is 12 inches or
bigger (if the wall is large enough). With a little ingenuity you
can write some BDL code that will automatically calculate the window width,
frame width and x position of the window on the wall so you don't get any
cautions or warnings. . </FONT></DIV>

fenestration area<BR></FONT><BR></DIV>
<DIV>
<P><FONT size=2>Greetings,<BR><BR>I am modeling a high-rise building in eQuest
which has a significant amount of fenestration as curtain wall. This curtain
wall, like many curtain walls, has metal frames around many small panes of glass
that make up the total curtain wall. My question is, how do you treat the frames
and the fenestration area? If I model each small pane of glass and add the
exact frame, this would probably overwhelm DOE2 due to the huge number of small
windows. If I model the glass as one big window, then is it correct to
just add the total width of the frame to each of these large windows? Also, some
of these curtain wall panes have fins to complicate things, so if I do one big
glass pane, then adding the fins would make huge fins on either side of the
glass. If you have dealt with modeling curtain walls, as probably many of you
have, please let me know how you have dealt with these issues.<BR><BR>Thank
you,<BR><BR>Renee<BR><BR>Renee Azerbegi<BR>RMH
