I am trying to do both daylighting and thermal simulation using Radiance and EnergyPlus through OpenStudio. My simulation is being completed successfully but whenever i re-run the same model (with no modification) i get a slightly different results for both lighting, cooling and heating loads. is there someone who had the same problem? how did you solve the issue? what can be the cause?
also i have put two daylighting controls in my model, but when i run the simulation i get the message that my secondary daylighting control was ignored. what could be the cause? I have set the primary daylighting control to 0.75 of the thermal zone and the secondary is set to control 0.25 of the thermal zone.
