Hi @Antop with the size of your model it is likely that the interior core of your building won't receive sufficient daylight without top lighting (skylights). If you only want to study daylighting controls in your perimeter zones then a daylighting point in each perimeter zone is probably sufficient. There are a few things to note:

  • If you are using EnergyPlus's daylighting engine then you do need to create and match interior windows between the perimeter and core zones, OpenStudio does not pass light through air walls when simulated with EnergyPlus
  • If you are using Radiance for the daylighting engine then light will pass through the air walls. However, the distribution of light in the core of the building will be poor without top lights. You can use illuminance maps in each zone to study the distribution of daylighting in each zone. You can view the illuminance map data using ResultsViewer to see which points in the space are most appropriate for daylighting controls.
