Annual Daylight Error - Light in Non Window Spaces

Getting odd results from this Annual Daylight Study, the Validate Model in Grasshopper says its validated but im getting sunlight in rooms with no Windows.

I’ve attached the HBJSON from the Dump Objects Component to help. (124.8 KB)

Hi @cflynn29,

This is possibly because the “VOID” rooms have the same display name. When the grids are created with LBT Grasshopper it uses the display name of the room, which results in multiple grids having the same identifier eventually causing some displacement in the ordering / restructuring of the sensors.

Can you check if it works if you exclude the rooms with duplicate display names? Or renaming them?
