Subject: [EnergyPlus_Support] Window U-factor follow up question
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?
