Weighting factors used in the irradiance calculation

Hi Greg,

As always, thank you for your rapid support. Lets suppose you have:

  • a spectrum of transmission, front reflection, and back reflection over a wide range (300–2500 nm) for transparent components, or
  • a reflection spectrum for opaque components
    and you want to use this to determine the respective values for the RADIANCE modifiers “plastic” or “trans.”

How do you get there? Is there a tool for this? The application are i.e. Ladybug/ Honeybee based simulations of either visual or broadband spectrum.

Best regards,
Simon
