Iterative daylighting calculations EnergyPlus
Is it possible to calculate the indoor daylighting illuminance during a timestep for two different situations: once with the shading (partly) closed and once with the shading open? For several timesteps, I need both values for evaluation in a Python plugin code, so ideally, I can specify in the code whether the second iteration of daylighting calculations should run and with which shading occlusion rate. At first glance, I didn’t find an option in EnergyPlus to iteratively calculate the indoor daylighting illuminance, although this seems the most straightforward approach.
Other options I’ve considered are: (i) Estimating the impact of the solar shading on the illuminance by integrating a (simplified) daylighting calculation into the Python script, but this may result in inconsistencies in the indoor illuminance values, or (ii) Starting a separate simulation for that timestep that calculates these values with the correct shading occlusion rate, but this would increase simulation time (if it’s even possible).
Does anyone have any ideas on how to address this issue? Thanks in advance!
