I’ve seen that LBT1.2 has just received a brand new function for calculation of Direct Sun Hours using radiance, that’s exciting! I was relying on Ladybug Legacy Sunlight Hours Analysis to do that, which was rather difficult to use for larger models.
When running a test simulation using both engines, I realized that the results are completely different. The radiance-based calculation reports about half of the direct sun hours of the ladybug component. It also appears to me that the orientation matters far less in the radiance-based than in the LB-Legacy. See two examples below, for south and easy orientation. The highest number is the LB Legacy, the lowest the new component from LBT1.2.
Which results should I be believing?
