[Trace-users] Specify Window Frame Type

Working on a LEED energy model in Trace. I typically use HAP, which allows
the input of a window frame type, and it then calculates the entire window
assembly U-value and SC, rather than just the glass.

I've had LEED reviewers come back and ask me for my window assembly
calcsand I was able to show how HAP was doing that
calc based on the frame type as well. However, I can't find anything
similar in Trace, and I'm getting nervous about how to show assembly
calculations to a LEED reviewer. I've had terrible luck in the past getting
assembly values from the manufacturer as well.

I spoke with CDS and they recommended modeling a small sliver of wall that
is representative of the frame, which seems quite tedious.

Has anyone either experienced this issue, and figured out a work around?
