Subject: Re: [EnergyPlus_Support] Window U-factor follow up question
There's a field for...it's late after a 14 hour grind...something like the ratio of U-frame to U-edge...memory is just not working, sorry. It's always greater than 1 (usually around 1.2) and takes care of the thermal break from CoG to Frame. WINDOW calculates
it for it's IDF output.

I am used to the overall window U-factor being calculated from three areas of the window � frame U-factor, edge U-factor and COG U-factor. The area weighted average of these three factors calculates the overall window
U-factor. EnergyPlus has inputs for frame U-factor and glass U-factor. How does the edge U-factor fit into the picture?
