How to Input Values for Honeybee Modifier – Reflective Glare Analysis

I am conducting a simulation to analyze the impact of reflectance properties of a single geometry on glare in an adjacent unit room. For this simulation, I intend to adjust reflectance, specularity, and roughness while disregarding the geometry’s transmittance and absorptance.

I plan to use the HB Translucent Modifier component and have the following questions:

  1. Regarding diff_ref input:
  • Can I directly input the reflectance value into diff_ref without any additional conversion?
  • Is there a separate spec_reflectance parameter, or does the component automatically calculate it based on spec_ and diff_ref?
  1. Configuring the geometry to be fully reflective without transmission:
  • How should I set diff_trans and spec_trans to ensure that the geometry does not transmit light and only reflects it?
  • In the HB Mirror Modifier, what values are used for diff_trans and spec_trans?

Thank you!
