Well, to start off the new year, I have a question on what the “curb” is in the LV-H report. The placement of the information, and the fact that it has an area and U-value (much the way the window frame does) leads me to believe it may be to account for Edge-of-Glass effects (if you look at Window5 outputs it has COG U-values, frame U-values and edge-of-glass U-values).<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I can’t see anywhere in the detailed edit mode to input curb information - I looked in both the “Glass Type Properties” and “Window Properties” Screens.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I found the following info in the DOE2 help file, but it looks like it only applies to skylights?
