Define your rooms, add doors and windows, and apply realistic textures or colors to surfaces. Assigning the correct reflection factors (e.g., 70% for ceilings, 50% for walls, 20% for floors) is critical, as these values directly impact your final lux calculations. Step 3: Importing and Placing Luminaires
feature allowed designers to list all rooms, luminaires, and energy data in a single comprehensive summary, removing the need for individual reports for every space. Enhanced Calculation Engine
: A dedicated view for outdoor spaces was added to the navigation bar, simplifying planning for exterior projects. Technical Specifications & Requirements Application of Dialux EVO in Retrofitting Lighting Systems
: Features larger fonts, attractive cover pages, and a dedicated contact page for project participants.
Challenge: High accent lighting (1500 lux on diamonds) but low ambient light (200 lux) without glare. Dialux evo 9 Solution: The designer used the new "Spotlight" tool to aim narrow beam MR16s. Using the real-time render, they saw exactly where reflections hit the glass cases. The project time was cut by 30% compared to version 8. dialux evo 9
: A new comprehensive list shows all rooms, their luminaires, and energy data in one place, removing the need for individual room outputs.
Are you looking to design an workspace or an outdoor project? Do you plan to import CAD/IFC files , or build from scratch?
DIALux evo 9 hummed. Her laptop fans roared. The progress bar inched forward: 10%... 40%... 85%. Elena held her breath. The software wasn’t just calculating light levels—it was simulating 14,000 photon bounces. Every reflection off the ceiling, every refraction through the virtual windowpane, every micro-shadow inside the weave of the rug.
This comprehensive guide explores the core features, workflow optimizations, and advanced capabilities introduced in DIALux evo 9, helping you elevate your design practice. 1. Key Features and Enhancements in DIALux evo 9 Define your rooms, add doors and windows, and
“I want the light to remember the afternoon my daughter took her first steps,” Mr. Alder said, pointing to a dusty blueprint of his living room. “Golden, soft, but with a sharp little shadow under the sofa.”
: Users can now insert project-wide information—such as descriptions, participant contact details, and a main project image—directly into a central "project mode".
: A faster engine provides better visualization and handling of complex objects.
DIALux evo 9 features an enhanced daylighting model. It calculates the impact of natural light based on specific geographic coordinates, time of day, and sky conditions (CIE sky models). This allows for precise planning of daylight-dependent control systems, helping projects meet LEED and BREEAM sustainability standards. Real-Time False Color Rendering Enhanced Calculation Engine : A dedicated view for
Highly detailed 3D furniture models drastically increase polygon counts. Use simplified geometric shapes for calculations, and swap them for high-fidelity models only during final rendering if necessary.
“Mr. Alder—walk into the room. The shadow is waiting.”
| Feature | DIALux evo 8.2 | DIALux evo 9 | | :--- | :--- | :--- | | | Hard to access, buried within export settings. | Easy access via a dedicated 'Project' tab. | | Luminaire Placement | No visibility of luminaire positions until the line was placed. Snapping tools were basic. | Live visualization of positions while drawing. New, advanced snapping tools (grid & angle) for precision. | | Luminaire Focusing | Required a full project calculation to see the light output of a single adjustable luminaire. | 'Show light visualisation' tool allows you to see output instantly, without calculation. | | Documentation | Required separate reports for each room. | Single, comprehensive room overview for all spaces and their energy data. | | Calculation Method | Standard photon shooter method. | Enhanced method that better handles detailed objects for faster and more realistic results. |
