How to use SurfaceProperty:SurroundingSurfaces in E+?

Hi,

In EnergyPlus, I want to have an extra IR radiation to one of my outside surface. I tried SurfaceProperty:SurroundingSurfaces, and changed the View Factor and Temperature Schedule, but the Output:Surface Outside Face Net Thermal Radiation Heat Gain Rate per Area does not change at all.

Here is my settings:

Name: W (one Outdoor surface defined in BuildingSurface:Detailed)

Sky View Factor:

Sky Temperature Schedule Name:

Ground View Factor:

Ground Temperature Schedule Name:

Surrounding Surface 1 Name: hot_surface (new name defined here)

Surrounding Surface 1 View Factor: 0.95

Surrounding Surface 1 Schedule Name: hot_surface_SCH (a const temperature schedule)

Any input will be appreciated. Thanks.
