Hi,
With the current workflow of HB Apply Daylight Control- The current daylight control type uses a continuous option OR a complete turn on/turn off option.
@chris If there is a stepped daylight control option available, could you please provide the workflow/component for the same! Thanks in advance!
Hi @ShefaliR ,
The EnergyPlus object that this component uses technically supports stepped controls. So you could always edit the IDF and simulate using the HB Run IDF Component. Or you could write your own Python component that uses the OpenStudio SDK to edit this object in the output OSM before simulating.
But, if you are concerned about this level of detail, the EnergyPlus object is already a very rough approximation because EnergyPlus is not a physics-based daylight rendering engine. So you are probably not getting accurate enough illuminace values from the EnergyPlus engine for the stepped controls to really be accurate.
So, for modeling real stepped controls accurately, I would recommend doing a HB Radiance daylight simulation to get accurate illuminance values. Then, you can use a component like the HB Daylight Control Schedule component to give you a starting lighting schedule from these results. And you can so some custom post-processing of the output schedule values to account for the stepped controls.
