why the design builder export opaque surface conduction equal to inside faces total conduction heat but not attach to the outside face?

edit

Do anyone has tried to export the report from the Design Builder,？I did a test and found that “Walls+Ground Floors+Roofs” value in the DB report is equal to“:Zone Opaque Surface Inside Faces Total Conduction Heat Gain Rate—Zone Opaque Surface Inside Faces Total Conduction Heat Loss Rate "，as also as“Surface Inside Face Conduction Heat Transfer Rate ” . But I wonder that why it is nothing to do with “ Outside Face Conduction ”，I think it should be equal to Surface Average Face Conduction Heat Transfer Rate . And I still can't export "Zone Opaque Surface Outside Face Conduction Gain"
