Dear @chris, on your advice I tried to follow the procedure via EnergyPlus, I hope in your reply, as soon as you have time.
So, I do a annual irradiance simulation (with a -dr 1) for a specific sensor and then put the 8760 values of the result in the EPW Data as diffuse radiation and set to 0 the all direct normal radition. Is that right?
For this sensor I create a simple cube 1x1x1, set a “Ground Zone” Room with a soil construction and then simulated with this procedure (see the below image). Than read only the results from the roof. Would be this the right way?
2 more questions:
Does the analysis also take into account the sky view factor and the view factor?
I tried to set the wind speed to 0, and this not affect the result of the analysis, is this not strange?
In the attached file I put the original EPW from EPWMap and not the edited EPW.
