Hi Santiago,
Thank you very much for your reply.
The "Adding Daylighting" video does show how to setting the simulation but it does not explain how to actually view the results.
In my case, it is important to work within the EnergyPlus environment and not taking the model out to an external one (lie Radiance), this is because I am going to do some batch simulations and export some CSV files with some data.
Like you, I`ve got the feeling that a DF analysis should not be very difficult to perform in EnergyPlus, and yet, I couldn`t manage to control it.
