First of all, I live in Spain. Here the legislation about lighting speaks of a couple of diferent glare measure factors, not only [GR] or [GRU], and I've been trying to calculate them with Dialux, but I've failed.
One of them is the [Fti] or [TI] (Disturbing glare index), for outoor lighting in pedestrian areas.
[Lv] is the equivalent veiling luminance and [Lm] is the average luminance of the road.
If [Lm]>5cd/m虏
We also have the [D] glare index for ambient outdoor lighting (for parks, green zones and other open areas)
[I] is the maximum value of luminous intensity (cd) in any direction that forms an 85掳 angle
with the vertical.
[A] is the apparent area (m虏) of the luminous parts of the luminaire in a perpendicular plane
to the direction of intensity [I].
Is there a way to calculate any of those with dialux? I've tried to find a way to obtain the veiling luminance in order to calculate TI with it, to no avail. With the [D] factor I am as lost as I can be.
Thank you in advance for your help.
