<DIV><FONT face=Arial size=2>The solution below can work, but does not take into
account the effect of shading due to fins and overhangs. For those
windows, a better approach is to define one of the windows, together with
its fins/overhang, and then use the window MULTIPLIER to establish the total
number of windows on the wall wall. If the overhang shades a significant
portion of the wall, in addition to the window, then the overhang can be defined
as a separate shading surface.</FONT></DIV>

<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
