I think you need to set this film coefficient to something high, like 1000 W/m2-K.

Subject: [EnergyPlus_Support] SurfaceProperty:OtherSideCoefficients
Dear Modellers
I want to set the external side of a surface to 21deg.C constant. This surface is an outside surfice facing the external environment. I am using SurfaceProperty:OtherSideCoefficients and I cannot get the desired result.
Anyone has experience with this E+ object?

SurfaceProperty:OtherSideCoefficients,
OtherSide_21deg_constant,!- Name
0, !- Combined Convective/Radiative Film Coefficient {W/m2-K}
21, !- Constant Temperature {C}
1, !- Constant Temperature Coefficient
0, !- External Dry-Bulb Temperature Coefficient
0, !- Ground Temperature Coefficient
0, !- Wind Speed Coefficient
0, !- Zone Air Temperature Coefficient
Always 21degC, !- Constant Temperature Schedule Name
No; !- Sinusoidal Variation of Constant Temperature Coefficient
--------------------------------------------------------
I am using this to get the surface temperature of the surfaces of interest. Is this right?
