[Radiance-general] 3. Re: GR Observer (Greg Ward)

Fri May 18 01:22:23 PDT 2018

Hey,

I found this online from AGI32:

https://docs.agi32.com/AGi32/Content/adding_calculation_points/Calculations_Glare_Rating_Concepts.htm

The Formula is GR = 27 + 24 lg (LVL/LVE ^0.9)

I checked the ones you sent (findglare and glarendx ), but I did see it, or
am I mistaken?

Thank you!

Mit freundlichen Grüssen,
