Set constant radiation heat transfer coefficient
Is there a way to set the constant radiation heat transfer coefficient in EnergyPlus?
I know that the convection heat transfer coefficient can be overridden using SurfaceProperty:ConvectionCoefficients. However, the radiative part (exchange with sky, ground, and air) seems to be calculated automatically.
Is it possible for the user to set the radiation heat transfer coefficient?
What I have tried so far: if I use SurfaceConvectionAlgorithm:Outside with SimpleCombinedSurfaceConvectionAlgorithm:Outside with SimpleCombined, it seems possible to treat convection and radiation as a single combined coefficient. But when I override the SurfaceProperty:ConvectionCoefficients, the radiation component still appears to be computed automatically.
Thank you in advance.



Here are my idf and csv results. When I set SurfaceProperty:ConvectionCoefficients for surface 3, the Surface Outside Face Thermal Radiation to Air Heat Transfer Coefficient value in Output:Variable is automatically calculated. Can the user set the radiation coefficient value?
