Questions on Glare Source Definition in HB-Radiance

Hello everyone! I am conducting glare analysis using HB-Radiance (Ladybug Tools) and would appreciate guidance on two implementation questions:

  1. 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)?

  2. 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
