Lighting technical analysis

An engineering analysis in Dialux that determines optimal lighting parameters — illuminance, uniformity, glare and equipment specification verified to current norms.

Far more than “enough lux” — engineering, not guesswork.

Calculations are run in Dialux against the active QMQ 2.01.05-2019 standard “Natural and artificial lighting” and the base normative package of Uzbekistan, with EN 12464-1 / ISO 8995-1 used for international projects.

What you get

  • Photorealistic visualizations of the light–shadow picture across switching scenarios.
  • Horizontal and vertical illuminance verified against normative requirements.
  • Uniformity coefficient — eliminates dark spots in the working plane.
  • UGR (glare index) with recommendations on fixture positioning.
  • Modeled and cylindrical illuminance for human-centric perception.
  • Zone-by-zone calculations driven by the activity in each space.
  • Fixture specification: models, optics, color temperature and control system.

How the calculation runs

  1. 01

    Approve the lighting concept

    Together with the interior designer we agree on tasks, character of the light and equipment types.

  2. 02

    Build the 3D model in Dialux

    Geometry, finish reflectance and the actual photometric data of the selected fixtures are loaded into the model.

  3. 03

    Run calculations to current norms

    Illuminance, uniformity, UGR and cylindrical lux are verified against QMQ 2.01.05-2019 (or EN 12464-1 internationally).

  4. 04

    Analyse results and optimise

    We refine the layout, optics or fixture selection and recalculate until every zone meets the spec.

  5. 05

    Deliver the report

    PDF with visualizations, tables and a final equipment specification — ready for procurement and expert review.
