Dialux Evo 9 Portable Now
DIALux evo 9 introduced a major overhaul of the software, specifically focusing on a completely redesigned documentation system, faster calculation engines, and improved luminaire placement tools. 1. Redesigned Documentation System
The output generation was entirely rebuilt to be more intuitive and visually professional.
Central Room Overview: A new comprehensive list shows all rooms, their luminaires, and energy data in one place, removing the need for individual room outputs.
Modern Layouts: Features larger fonts, attractive cover pages, and a dedicated contact page for project participants.
Customizable Content: Users can now edit disclaimers and imprints individually.
Integrated Graphics: Isoluminance curves, false colors, and value charts can now be displayed together in a single floor plan.
Glossary: A new glossary clarifies formula symbols and abbreviations used throughout the reports. 2. Enhanced Luminaire Placement New tools significantly speed up the design phase.
Visualized Distribution: In the CAD view, you can see dimensions, construction directions, and visualizations of the luminaires before they are placed. dialux evo 9
Line Arrangement: Luminaires can be distributed along lines based on a specific number or set distance.
Advanced Snapping: Includes a new length grid and angle snap for higher precision.
Field Placement (9.1 Update): Place luminaires in a grid based on X and Y directions or by specific distances between units. 3. Performance & Visualization
New Calculation Method: A faster engine provides better visualization and handling of complex objects.
Show Light Visualisation: This tool allows you to see the light output of a single selected luminaire instantly without running a full project calculation.
Realistic Rendering: Lighting effects on object surfaces are rendered with increased realism. 4. User Interface & Workflow
DIALux evo 9 is a powerful lighting design software used by architects and engineers to simulate and calculate lighting for interior and exterior spaces. This version introduced a major overhaul of the documentation workflow and calculation engine to improve efficiency and visual quality. 1. Key New Features in DIALux evo 9 DIALux evo 9 introduced a major overhaul of
Redesigned Documentation: A completely revised output design features a more structured layout with larger fonts and more attractive cover pages.
Show Light Visualization Tool: This function allows designers to view the light output of a single selected luminaire in real-time without calculating the entire project, which is ideal for aiming spotlights.
New Calculation Method: Includes a "photon shooter" engine that significantly speeds up calculations for complex scenes with many objects.
Streamlined Project Tab: Consolidates project information, allowing for faster entry of descriptions, images, and contact details for participants.
Enhanced Luminaire Placement: Version 9.1 added field-based placement, allowing users to arrange luminaires by quantity or specific distance without manual calculations. 2. System Requirements
To run DIALux evo 9 smoothly, your system should meet the following Hardware Requirements from DIALux: OS: 64-bit Windows 10 or 11. CPU: Multi-core processor (4–8 cores recommended).
RAM: Minimum 4 GB; 8–16 GB recommended for professional use. 4) Import backgrounds & CAD
Graphics Card: Must support OpenGL 3.2 with at least 1 GB VRAM (2 GB+ recommended for large projects). 3. Step-by-Step Workflow Guide

6) Add light sources
- Luminaire catalog: Insert → Luminaires → Manufacturer catalog (search or import .ldt/.ies).
- Place luminaires manually or use grid/array tools: Insert → Placement → Grid/Array.
- Set mounting height, orientation, luminous flux, and photometric file (IES/LDT) in properties.
- For natural light: Insert → Openings (windows, skylights) and set glazing transmittance.
4) Import backgrounds & CAD
- Import DWG/DXF: Insert → Import → CAD file. Place it on the correct storey and scale.
- Use background image: Insert → Image, then scale and trace geometry.
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.
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.
Step 4: Calculation and Analysis
Click "Calculate." Within seconds, you get:
- Pseudo-colors: An overlay showing illuminance (lx) as a color gradient.
- Isolux lines: Contour lines of equal light intensity.
- Value table: Minimum, maximum, and average illuminance, plus uniformity ratios (U0, U1).
The Major Overhaul: The New Calculation Core
The headline feature of DIALux evo 9 is the new calculation core. While previous versions relied on Radiance for calculations, evo 9 introduced a proprietary, physically based path tracer developed in-house by DIAL.
- Improved Accuracy: The new engine allows for a unified simulation of daylight and artificial light. It creates physically correct results that mimic real-world lighting behavior, including complex interactions between light and materials.
- Unified Workflow: Previously, users often had to switch contexts between indoor, outdoor, and street lighting. The new core creates a seamless experience where these zones can be calculated together in one model without exporting to different modules.
- Faster Results: The optimization of the calculation algorithms allows for significantly faster calculation times, particularly in complex scenes with high polygon counts or intricate luminaire arrangements.
Part 2: The User Experience – From Novice to Expert
One of the struggles of older lighting software was its steep learning curve. Dialux evo 9 aims to solve this through "Intelligent Defaults."
