2. DIALux evo 01. Introduction DIALux evo is a free, professional application for planning indoor, outdoor, sports, and street lighting. Developed by DIAL GmbH, it lets engineers model buildings in 3D, place manufacturer luminaires, and run precise photometric calculations. www.dialux.com
3. DIALux evo 02. Why DIALux evo The industry standard for verifying lighting installations before they are built. www.dialux.com Deliver physically accurate illuminance and luminance calculations engineers can trust. Integrate CAD, BIM, and manufacturer luminaire data in one unified workflow. Support compliance checks against EN, IES, and other lighting standards. Give engineers a free, vendorneutral platform for professional lighting design.
4. DIALux evo Core Workflow A project starts by building the scene: importing CAD/BIM geometry or modeling rooms, streets, or outdoor areas directly in DIALux evo. Engineers then select luminaires from a catalog of 500+ manufacturer plugins, position them precisely, and define surface reflectances. The engine processes direct and indirect light, generating falsecolor renderings, isolux diagrams, and numeric reports ready for approval. 03. www.dialux.com
5. DIALux evo 04. www.dialux.com Direct CAD, DWG, DXF, and BIM/IFC import for accurate site geometry. Live daylight simulation using real geographic location and sky models. Combined radiosity and ray-tracing engine for precise indirect light. Automated reports, 3D renderings, and false-color visualizations. Key Features
6. DIALux evo 05. Calculation Engine DIALux evo calculates illuminance and luminance using photometric data supplied in IES or EULUMDAT format. The engine models direct light, inter-reflections between surfaces, and daylight contributions together, so results can be checked against maintained illuminance, uniformity, and glare (UGR) requirements. Calculation grids can be customized per surface, and results export as PDF reports or CSV data. www.dialux.com
7. DIALux evo 06. www.dialux.com Application Areas Indoor Lighting Outdoor & Street Lighting Emergency Lighting Office, retail, industrial, and residential interior calculations. Road, area, sports field, and facade lighting per regional standards. Escape route and open area emergency lighting verification.
8. DIALux evo 07. www.dialux.com Standards & Compliance DIALux evo supports verification against EN 12464-1 (indoor workplaces), EN 13201 (road lighting), EN 1838 (emergency lighting), and IES/ANSI recommendations used in North America. Manufacturer plugins deliver certified photometric data directly into the software, so results reflect real luminaire performance rather than generic assumptions, giving engineers defensible documentation for code compliance and client sign-off.
9. DIALux evo 08. www.dialux.com Industry Adoption Used by lighting engineers and architects in over 180 countries worldwide. Free to download and use, with no licensing fees for professional projects. Backed by an ecosystem of 500+ manufacturer luminaire plug-ins. Referenced in university curricula and professional lighting certifications.
10. DIALux evo 09. Engineer Workflow Engineers typically start by importing a floor plan or BIM model, then use DIALux evo's built-in tools to define rooms, streets, or outdoor zones. Luminaire placement can be automated with the auto-planning assistant or done manually for full control. Once calculations finish, DIALux evo generates standardized documentation, including isolux plots, UGR tables, and 3D renders, ready to submit to clients or regulatory bodies. www.dialux.com
