Download now – DIALux evo 8.1

The latest version of DIAL’s lighting design software is DIALux evo 9.2 – and as always available for download free of charge. * Please note that the following article describes an older version of DIALux. *

DIALux evo 8.1 is not only faster but also offers many new features which make the user’s work easier. Among the new features are a help function, an assistant for importing DWG plans and documentation for zones extending over several floors.

Zones extending over several floors
With DIALux evo 8.1 the user can for the very first time generate documentation for zones extending over several floors. One example is planning for a stairwell with several flights of stairs. The user can define a zone extending over several floors. In this segment lighting can be planned for the whole stairwell. All the luminaires used are then listed in the documentation so that the designer immediately has an overview of the number of luminaires and the energy consumption of these products over all flights of stairs. You will find a detailed article about this here.

DWG import assistant
Another new feature is the DWG import assistant. As soon as a DWG plan has been imported, a window appears in which the following steps are described:
Step 1: Define coordinates: The designer defines a system of coordinates in the DWG plan by setting the origin and the rotation.
Step 2: Defining the scale: The designer can click on a known distance in the plan and then type in the length in metres. Normally use is made here of chain dimensioning which is frequently marked in the plans for this purpose. The new DWG assistant in DIALux evo is then able to define the measuring unit explicitly. The second option is of interest to designers who already know the measuring unit of their plan. For such cases the assistant has a selection box in which the unit can be selected directly.

Furthermore, in the new version DIAL has included a window for messages where useful and important information pops up in different situations. For example, DIALux evo notifies the designer when the number of luminaires is not sufficient for the luminance required or if normative evaluation of the luminaires is not possible because they are positioned wrongly. There will be further development of such messages in coming versions of the software.

Selecting individual objects and luminaire layout together
With this update it is easier to select luminaires. There is no longer a difference between the layout of individual luminaires in a linear or rectangular arrangement and manually positioned individual luminaires. The user can now mark all the luminaires with one click and move them or remove them from the project. 

Maintenance factors in accordance with JIEG-001
For planning projects in Japan there is something new. With the update to DIALux evo 8.1 there is a selection option for the Japanese standard in the norm control centre. With this the designer can now select the maintenance factor method in accordance with JIEG-001. Documentation of the maintenance factors is in the reports.

The most important new features in DIALux evo 8.1 are clearly summed up again in the video below.
