I wanted to calculate Spatial Illuminance inside the room. Instead of calculating planar illuminance, integrating sphere can account for illuminance from all directions.
I found some solutions in the RADIANCE forum: https://discourse.radiance-online.org/t/spherical-sensor/2651/4
However I kind of don’t know how to apply these codes in honeybee.
I tried using a small sphere (subdividing with triangle) / small cubic (with 6 surfaces) in the same position, is it right to use the sum of all the surfaces to represent the integrating sphere / spatial illuminance?
