DIALux evo 6.2
New features and improvements

Improvement of daylight calculation

• The transmission diagram has been visually improved. The theta angle is now documented in the printouts.
• The part “daylight information” has been added to the room summary printouts.
• Calculation surfaces for daylight factors are showing the average value of the daylight factors.
• The layout of daylight factor calculation surface outputs has been reworked.
• Openings as windows and doors can now be placed via drag & drop also in 2D.
• DDLS files for façade systems can now be placed via drag & drop.
• Roof lights are now aligned according to the shape of roof when being copied.
• The progress of calculation daylight and façade systems is shown in a more detailed way.
• The calculation of the refraction index works correctly now, also for glass type “no glass”.

Performance boost for loading projects

• Projects that are stored with DIALux evo 6.2 or above can be loaded up to 50-80% faster than before. The exact result depends on the type of the saved project.

Improvements in road lighting

• New IES file import assistant: Geometric dimensions for luminaire case and light output can be entered. The user is guided by a visual assistant.
• Road profiles for documentation can be selected during the planning.
• Results which fulfil and those which do not fulfil any normative condition are now highlighted in the result table.
• According to EN 13201:2015, DIALux provides an optional TI calculation of C and P classes, if desired.
• The optimization now uses 5 parameters as there are pole distance, light centre height, boom angle, light overhang and now also the minimal energy consumption needed. For this optimization, DIALux uses all equipment information given for a luminaire.
• The layout of road planning printouts has been improved to fit to one page for most cases.

Documentation of luminaire positions

• The printouts show luminaire coordinated within the ground plan as well as in a position table.
• The luminaire orientation of C0/G0 planes are documented in CAD and ground plan.
• Luminaires are systematically numbered to be easier found in table and ground plan.
• Users can freely define a coordinate system for each room which is used as reference point for documenting luminaire positions.

Improvement of lamp tool

• The display of the correlated colour temperature (CCT) has been improved. In many cases the given spectrum did not fit to the CCT. The CCT is now always been taken from luminaire data.
• The declaration of the colour rendering index (RCI) has been improved.
• Different technical terms as well as their translation have been improved.
• The way of how to select luminaires and luminaire arrangements in the lamp tool has been changed.

This includes vertical louvre blinds and textile blinds, skylights, foils and prismatic systems. The lighting designer places and configures multiple daylight system in layers.
Depending on the date, time, orientation of the building and sky model DIAlxu calculates the daylight factor and illuminance values inside the building.

All results are available in the reslut overview and in the project documentation. There is also documentation about the daylight situation and detailed product descriptions.
The light-guiding systems are using the new hemispherical transmittance chart. With just one click the user can transfere systems to other windows.
For product selection you can use electronic catalogs of manufacturers of sunscreen and daylight control systems.

Alternatively, you import product data via the new ODLS (Open Daylight System) - format or the DIALux DDLS format.
It includes images and product descriptions as well as all photometric data.

All tools for generating calculation objects can be found in the new mode calculation objects.
  

Print outs

• There is a colored floor plan, in which the building geometry, lighting, furniture and calculation areas are displayed. It is automatically visible in the room summaries. Printouts of individual calculation areas use this space view also to show the position of the surface. The calculation area is highlighted in the view.
  
• In the room summary the result of calculation of the reference plane, the results of EN 12464-1 surfaces are shown separately. The layout will be improved.

These redundant outputs are removed from the templates. However, the user of DIALux evo they can still select them and adjust its output individually.
  
• The UGR will be calculated for a range of angles in discrete viewing directions. This information is displayed in a star-shaped graph, so that the user can interpret the UGR values easier.
