The output generation was entirely rebuilt to be more intuitive and visually professional.
Minimum 8 GB (16 GB or more highly recommended for large IFC files).
When you define a room profile (e.g., "Conference Room" or "Classroom"), DIALux automatically loads the required target lux levels, uniformity ratios, and maximum UGR limits. The software then provides a clear pass/fail checklist in your final documentation. 5. Tips for Optimizing Performance in DIALux evo 9
She zoomed in on the east window. No physical sun was coming, so she built her own. She clicked . Instead of a standard daylight spectrum, she manually entered a color temperature curve: 3200K at the horizon, fading to a deep indigo at the zenith. She added a volumetric fog—just 12% density. The light began to spill across the digital floorboards. dialux evo 9
Ensuring safety and productivity in manufacturing or warehouse environments.
One of the most immediate improvements in DIALux evo 9 is the refinement of its user interface and 3D modeling capabilities. Previous iterations often required a steep learning curve, particularly for those accustomed to CAD software. Evo 9 addresses this by offering a more intuitive workflow that mirrors the logic of architectural design. The software allows for the quick construction of complex geometries, enabling designers to build rooms, insert doors and windows, and modify textures with ease. The improved "modes"—ranging from "Construction" to "Light" and "Documentation"—guide the user through the logical steps of a project, ensuring that the workflow remains structured and efficient.
: Place luminaires in a grid based on X and Y directions or by specific distances between units. 3. Performance & Visualization The output generation was entirely rebuilt to be
: Version 9.1 added field-based placement, allowing users to arrange luminaires by quantity or specific distance without manual calculations. 2. System Requirements
Elena smiled and looked down at her phone. The DIALux evo 9 app showed the live Bluetooth lux reading: 151 lux on the floor, 81 lux on the wall.
is a free, advanced computer-aided design (CAD) software designed for simulating and visualizing both interior and exterior lighting. It enables users to create virtual environments, model buildings, and calculate precise lighting requirements (illuminance, light power density, etc.). With DIALux evo 9, designers can: Import CAD drawings or IFC files for complex modeling. Simulate daylighting and artificial lighting together. Achieve compliance with international and local standards. Key Features and Enhancements in DIALux evo 9 The software then provides a clear pass/fail checklist
DIALux evo 9 is lighting design software that allows professionals to plan, calculate, and visualize lighting for both indoor and outdoor spaces. Unlike its predecessor (DIALux 4), which was room-centric, DIALux evo is building-centric. It allows you to create a complete 3D building model, import CAD or BIM files, and then plan the lighting for the entire structure as a cohesive whole. This integrated approach allows for the realistic simulation of daylight and artificial light within a single project. The software was hailed for empowering users to create more efficient lighting designs thanks to its array of new features.
Understanding what changed from version 8 to 9 helps to highlight the significance of this release. While DIALux evo 8 was a powerful tool, version 9 represented a maturation of the platform. Here is a comparison table of their key differences:
A practical improvement in 9.2 was the implementation of image caching for automatically generated views, making the documentation creation process smoother and more responsive.
