One consideration from my understanding is that the .ddy file provides the design day data. In your case, it looks like the winter design dry bulb in the ddy file is -5.2C (January), yet your Github suggests you are trying to replicate a -3C outdoor air condition. Wouldn't the simulation also account for the thermal mass of your wall assembly? All this to say, there are many ways in which the results could be affected. I still hope more of the E+ experts chime in.
