I am using the EMS in EnergyPlus and customizing surface variables such as Dry Bulb Temperature, Wet Bulb Temperature and Wind Speed. I am imposing a Surface Dry Bulb Temperature that takes into account the convective and radiative heat exchanges between the external surface and the environment. If I run the simulation with EnergyPlus, though, the heat gain from the sun is taken into account as well, using the radiation data in the EPW file. How can I turn it off? I can easily regulate the convective heat exchange, customizing the convection coefficient on each surface, but what can I do with the radiative heat exchange? If I set to 0 the incoming radiation I eliminate this contribution, but I also eliminate the sun contribution in terms of light and that's not ideal.
