Hello everyone! I am conducting glare analysis using HB-Radiance (Ladybug Tools) and would appreciate guidance on two implementation questions:
-
Computer Monitor as Glare Source
After defining a computer monitor as a Radiance glow source (250 cd/m²), will Imageless Annual Glare automatically include it in DGP calculations?
If not, what specific steps are needed to enforce its recognition (e.g., source tagging/modifier adjustments)? -
luminance_fac in “Imageless Annual Glare”
The “luminance_fac” parameter (set to 100 cd/m²) states it filters glare sources based on sky patch brightness.
Does this threshold:
（1）Apply only to sky patches, or also to artificial sources like monitors?
（2）Have established guidelines for hybrid (natural + artificial) glare scenarios?
Thanks in advance
Elaine
