New in DIALux evo 13: Obtrusive Light Calculation

The main focus of DIALux evo 13 is the calculation of light obtrusive light. This powerful new feature allows planners to precisely calculate and evaluate light immissions in outdoor areas. With DIALux evo 13, lighting designers and engineers can ensure that lighting installations comply with all relevant standards and regulations for obtrusive light and reduce light pollution.

You now have access to a new light scene in DIALux evo for calculating obtrusive light, which automatically considers a maintenance factor of 1 and allows all outdoor luminaires to be added with a single click.
With a new tool, you can place calculation objects for obtrusive light assessment and determine the following values: I (light intensity), ks (glare value), as well as the light flux ratios Ruf, Rul, RULO, and RDLO.
A checklist helps you to verify if all necessary steps for an obtrusive light calculation have been implemented.
The glare value (ks) can be visualized as isolines, false colors, or value diagrams, allowing for intuitive analysis in complex scenes.
DIALux evo 13 provides new output layouts for documenting the results of an obtrusive light calculation.
At this development stage DIALux evo supports the following norms and regulations:
CIE150:2017, EN 12464-2:2014, LAI:2012, ÖNORM O 1052:2022

Yay good news! Would love if you add AS/NZS 4282 (Australian standard obtrusive light standard) like AGI32 has. Then we can kiss AGI goodbye forever.
