Dialux Evo 9

DIALux evo 9, released in April 2020 , marked a major evolution in lighting design software, primarily focusing on a complete overhaul of its documentation workflow and enhancing the efficiency of outdoor planning.   The Documentation Revolution   The "full story" of version 9 is centered on making professional reports easier to generate and customize.   Total Redesign : The output section was completely rewritten for better clarity and structure. Centralized Project Hub : Users can now insert project-wide information—such as descriptions, participant contact details, and a main project image—directly into a central "project mode". Flexible Layouts : For the first time, users could choose from different layout alternatives for each page, allowing for better arrangement of images and text. Consolidated Room Overview : A new room list allows designers to see all luminaires, energy data, and room elements in one compact summary, removing the need for individual room reports. Visual Enhancements : Users can now show isoluminance curves, false colors, and value charts simultaneously on a single floor plan.   Improved Design & Workflow Features   Beyond reporting, version 9 introduced several practical tools for the design phase:   Outdoor Planning Overhaul : The navigation bar was extended to include a specific outdoor view , and users can now visualize the contours of both indoor and outdoor spaces simultaneously during construction. Precise Luminaire Placement : The software revised light lines and snap mechanisms (including angle and length snaps), enabling users to distribute luminaires along a line by either a specific number or a set distance. Realistic Calculations : A new calculation method was implemented to visualize complex objects more realistically and speed up processing time. Stability & Fixes : Version 9 resolved long-standing issues with complex geometries and improved the reliability of IFC file imports .   Technical Evolution   Platform Transition : As part of this release, DIALux moved toward converting vector graphics to raster for documentation to improve stability in large-scale projects, though this occasionally resulted in larger PDF file sizes. Maintenance & Standards : The update restored the ability to reassign standards to existing road projects and fixed errors in the ROVL and EN 13201:2004 standard transitions.   While DIALux evo has since moved to version 13, version 9 remains a landmark update that defined the modern professional reporting standards used by designers today.   DIALUX EVO 9 : DOCUMENTATION EXPLAINED

DIALux evo 9: The Complete Guide to the Next Generation of Lighting Design Software In the world of professional lighting design, precision is not just a goal—it is a requirement. For over two decades, DIALux has stood as the global gold standard for simulating, calculating, and visualizing light. With the release of DIALux evo 9 , the German-based DIAL GmbH has not simply updated an existing tool; they have fundamentally re-engineered the user experience and the underlying calculation engine. Whether you are a seasoned lighting engineer, an architect, or an electrical planner, this version demands your attention. This article provides an exhaustive deep dive into DIALux evo 9, exploring its new features, performance benchmarks, workflow enhancements, and why it is the definitive tool for professional lighting design in 2024 and beyond. What is DIALux evo 9? A Brief Refresher Before dissecting the new features, it is crucial to understand what DIALux evo actually is. Unlike its predecessor (DIALux 4), which was based on a pure CAD (Computer-Aided Design) logic, DIALux evo introduced a "room-based" and "building-based" modeling paradigm. DIALux evo 9 continues this philosophy, but with a critical shift: it is faster, smarter, and more intuitive. DIALux evo 9 is a complete, free-of-charge software solution for professional lighting calculation. It supports all major light planning standards, including EN 12464, DIN 5035, and LEED requirements. It allows designers to import 3D models, place luminaires, calculate illuminance, glare (UGR), and produce photorealistic visualizations. What’s New in DIALux evo 9? The Headline Features If you are upgrading from version 8 or 8.1, you will notice the changes immediately. DIALux evo 9 is not a cosmetic facelift; it is an architectural overhaul. 1. The New Calculation Kernel: The "Speed Engine" The most significant improvement in DIALux evo 9 is the complete reworking of the calculation core. In previous versions, calculating complex scenes with thousands of luminaires could take minutes. DIALux evo 9 introduces a multi-threaded, GPU-optimized calculation engine.

Real-time feedback: Changes to luminaire placement or light levels are now visible almost instantly in the pseudo-color rendering. Raytracing speed: Photorealistic renderings are now calculated 3 to 5 times faster than in DIALux evo 8.

2. Intelligent Object Management (The "Lasso" Revolution) Managing hundreds of luminaires used to be tedious. DIALux evo 9 introduces a lasso selection tool combined with a property panel that allows you to change light sources, color temperatures, and light output ratios (LOR) for multiple luminaires simultaneously, even across different floors of a building. 3. Revamped Photorealistic View The visualization engine has been overhauled to support PBR (Physically Based Rendering). What does this mean for you? dialux evo 9

Deep shadows: No more washed-out renders. Shadows are now sharp or soft based on real-world light physics. Material response: Materials like brushed metal, glass, and fabric now react to light realistically. A red wall will cast a subtle red hue onto adjacent surfaces.

4. Native BIM Integration (IFC 4.0) While DIALux evo has supported BIM for years, version 9 natively supports IFC 4.0 (Industry Foundation Classes). This is critical for large-scale projects.

You can now import models from Revit, ArchiCAD, or Vectorworks without losing material definitions or structural elements. Collision detection: The software alerts you if a proposed light fixture intersects with a ventilation duct or beam from the imported BIM model. DIALux evo 9, released in April 2020 ,

5. The UGR (Unified Glare Rating) Assistant Glare is a major factor in workplace lighting. In DIALux evo 9, the UGR analysis has been separated into its own dedicated assistant.

It automatically calculates the UGR according to the standard observer positions. It highlights problematic luminaires in red directly in the 3D view. It suggests "cut-off" angles or shielding options for standard luminaires.

The Workflow: From Zero to Professional Calculation in evo 9 Let’s walk through a typical project to understand how DIALux evo 9 feels in practice. Step 1: Project Setup When you launch DIALux evo 9, the new "Project Wizard" asks three questions: Centralized Project Hub : Users can now insert

Room or Building? (Do you have one room or a multi-story structure?) Standard? (EN 12464, LEED, etc.) Lighting type? (Daylight, Artificial, or Mixed)

Step 2: Geometry Creation or Import You can draw rooms manually using the "Wall tool" in seconds, but the true power lies in import.
