I have a big zone and I want to add some daylighting reference points. In energy plus there are just 10 reference points and I need more than this for my zone. Is there any way to add more points?

I am not sure how EnergyPlus reads in the Energy+.idd now, I don't know if it is done at compile time or simulation run time. If it is read in at simulation run time, you might be able to edit the Energy+.idd file in your installation of EnergyPlus to include more daylighting reference point fields in the Daylighting:Controls object.

Thanks a lot! That worked.

Is the problem with IDF Editor or with EnergyPlus? I believe in EnergyPlus, for the Daylighting:Controls ninput object, you can have as many Daylighting Reference Points as you need by just editing the IDF or epJSON file with a text editor. If you want to edit the IDF file with the IDF Editor you need to update the Energy+.IDD file so that it shows as many fields as you need.
