[EnergyPlus_Support] Outside Surface Temperature - Conduction Finite Difference Method

Dear EPlus users,

When I run a simulation using the ConFD algorithm of a test hut (3m by 3m by 3m - 0 degree North orientation) located in Greenville, South Carolina. The outside temperature of the north facade during first two weeks of July comes to be 25-30 degree Celsius more than the corresponding South Outside surface temperature at 12:00 Noon. I have checked the sun path diagram of GreenVille for the first two weeks of July and it looks to me that the south wall outside surface temperature needs to be considerably more than the North wall. Unless, there is a considerable Heat conduction from the east and west walls towards the North. (From the east wall during the morning and from the west during the evening). Am I missing something here? 

Thanking you in advance,
Niraj Poudel
