It is possible to use data from two epw files in EnergyPlus?

Dear community, I am trying to do an energy simulation of a case study with a courtyard. I have run a cfd simulation to know the courtyard temperature (which is not the same as in the outdoors, given the tempering effect of the courtyard's microclimate). Now, I want to perform an energy simulation of the building, using the outdoor epw file but also using the cfd results as boundary conditions of the courtyard surfaces. I am new in Energy Plus. I have used it through Honeybee before, but I think I need to go to the idf itself to modify it to achieve what I want. At the moment, I have tried to use the other side coefficient in the courtyard surfaces. However, this allows me to change surface temperatures, bet then radiation is not accounted. For that reason, I am not sure if this way is correct. Has anybody tried something similar? do you have an idea about how to proceed to do this? I haven't found information about using different temperature data apart from the OSC option.

Thank you in advance. Victoria.

This might be possible with the EnergyManagementSystem. Running a model and checking the EDD file (using this is useful), it looks like the temperature could be set with an actuator at per-surface level.

I have a similar problem. I am trying to use the 'otherside coefficient' option just to change the temperature in front of facade for specific surfaces. Briefly, i am trying to expose the facade to two different air conditions. One surface will be exposed to outside weather conditions specified by the epw file and just another specific surface of the building will be exposed to a different temperature. I am not concerned about the radiation or wind etc other than the temperature. Is it appropriate to use the OSC option for this to set the 'other' temperature or should I use something different? Thanks in advance.
