DIALux for Interior Lighting

Module 4: Calculation


Understand how to calculate and evaluate lighting results. Set up calculation objects, adjust parameters, and visualise outcomes with isolines and false colours.

This is the fourth of seven modules from the online course DIALux for Interior Lighting.

Calculation objects

Working plane

Check the input for the working plane and start your calculation. Afterward, you'll see results such as isolines in 2D and 3D, as well as visual evaluation indicators based on utilisation profiles.


Duration: 04:14 min

Calculation objects

Learn how to insert calculation objects like rectangular or polygonal surfaces, define their size, name, and position. DIALux shows all relevant details in the sidebar, making evaluation easier.


Duration: 04:49 min

Calculation parameter

Understand the different calculation parameters and how to apply them correctly. Icons in the result overview help you interpret the data. You’ll also get a helpful tip on how to quickly evaluate real surfaces in your project.

Duration: 05:37 min

Setup & Evalutation

Results monitor

Get a complete overview of your calculation results – always visible and linked directly to the CAD window. This overview helps you evaluate values and optimize your lighting concept throughout the planning process.

Duration: 02:47 min

Setting options

Explore the calculation settings and decide what should be included – such as all or individual light scenes, with or without furniture. For larger projects, speed-up options help accelerate the calculation.

Duration: 06:35 min

Measuring grid & height offset

Check all inputs for your calculation object and make use of the height offset to generate results on multiple levels. Use full flexibility to adjust the measuring grid and define exactly what should be calculated.

Duration: 03:52 min

Cut-outs in calculation surfaces

Create rectangular or polygonal cut-outs in calculation surfaces when specific areas should be excluded. We show you how to remove measuring points to better reflect real conditions.

Duration: 03:47 min

Settings of the working plane

Modify the working plane by setting its name, height, and wall zone. You can also configure the evaluation grid – either according to EN 12464-1 or with adaptive illuminance for more precision.

Duration: 05:30 min

Work areas acc. EN-12464

Place task area surfaces to evaluate workplaces in accordance with EN 12464-1. The surrounding and background zones are created automatically. Learn how to input data correctly and understand the logic.

Duration: 07:34 min

Results display

Isolines

Visualize the isolines and adjust settings such as label size or the number of lines. Save your preferred styles for consistent and clear documentation in your future projects.

Duration: 03:59 min

False colors

Apply false colors to surfaces and calculation areas to highlight illuminance and luminance levels. Customize the appearance using presets to ensure consistency in your project documentation.

Duration: 04:37 min

Value charts

Display point illuminance values and identify minimum and maximum levels. Adjust text size for better readability and save presets to streamline visualization and documentation.

Duration: 02:21 min
