What is DIALux Evo? Why use this tool?

por Rogério França


In the last years, lighting software or lighting design simulation software have proved to be extremely useful in the process of designing artificial lighting projects.


The computer programs help, a lot, in the work of the designers, because they perform in a short time the adequate dimensioning and launch of the lighting system, reconciling aspects of visualization of the luminotechnical effects, produced by artificial lighting, to the criteria of visual performance and energy efficiency, making it possible to examine the impact of different project decisions. [1]


The choice of specialized software for a lighting project, adapted to the normative criteria, guarantees a project with pleasant environments and energy efficiency, thus enabling the reduction of energy consumption due to artificial lighting.


Based on the study by Kaempf (2016), it presents the preferences of about a thousand professionals from different countries in relation to the various tools indicated for lighting, modeling, and simulation. DIALux, in turn, stood out among the most used software by professionals in aspects related to lighting, simulation, and visualization. [2]

It must be remembered that the success of the program is due to a series of factors and advantages that we will list here, but after all, what is DIALux? What are the main advantages of using this lighting tool?


DIALux, is a parametric tool for modeling and luminotechnical calculation, aimed at obtaining measurable technical results from light, which allows us to create 3D environments, to calculate and to visualize data and results through an intuitive graphical interface.


Developed by the German company DIAL, DIALux is one of the most used programs in the world, the software is used by more than 680,000 lighting designers around the world. It is available in 25 languages and has partnerships that allow the use of the software with different lighting catalogs from leading manufacturers. [3]


DIALux is available in two versions:

DIALux 4.13 DIALux Evo
Original version, launched in 1994 and no longer receives updates. Version launched in 2012, featuring several innovations, enhancement of resources and receives periodic updates.


Dialux Evo is a true visual effects laboratory, enabling the real simulation of light effects interactively, making it possible to work associatively, the site, the building and its environments, and the isolated units. Unlike many lighting software, DIALux Evo is completely intuitive, simple, and affordable.

The main advantage of DIALux Evo in relation to its competitors is the cost benefit, as it offers accurate and complete lighting studies in a professional manner and it is available free of charge.

Main advantages of DIALux Evo

– Integration with BIM (Building Information Modeling).

– Possibility of importing 3DS objects (3D Studio Max, SketchUp).

– Possibility to model the building as a whole, regardless of the number of floors.

– Access to the IES and ULD files of the main manufacturers in the world.

– Library management: objects, colors, textures, and lamps.

– Calculation of energy efficiency and energy savings.

– Calculations of internal and external lighting simultaneously.

– Possibility to create lighting scenarios and simulation of natural light.

– Possibility to create materials and textures using JPG files.

– Possibility to export lighting projects in DWG.

– Complete and personalized reports.


Where to study?

Specialization courses that offer disciplines centered on DIALux have been the most sought after. The Master in Lighting & Design Practices in Architecture and the Master in Lighting Design course at IPOG offer two modules in the curriculum, another option is the short course in DIALux Evo – Luminotechnical Calculations.
