Thermal Digital Twin EGEON

Project EGEON: Thermal Digital Twin for BREEAM Certification

For the EGEON project, Droneview.be conducted an advanced thermal drone inspection. The objective was not merely to capture images, but to create a complete Digital Twin based on radiometric data. This report served as technical substantiation for the building’s BREEAM certification file.


The Challenge: Detecting Invisible Heat Loss

For large-scale buildings like this one, manually tracing insulation anomalies and thermal bridges is an impossible task. The client required a system that:

  • Detects thermal deviations at great heights and on hard-to-reach facades.
  • Directly localizes data spatially within a 3D model.
  • Provides absolute temperature measurements for technical validation.

Our Methodology: Radiometric 3D Mapping

Using the DJI M30T, we performed a combined flight (thermal + visual).

  • Dataset: 1,321 captures processed into a point cloud of over 20 million measurement points.
  • Resolution: A razor-sharp visual GSD of 2.49 cm/px and a thermal GSD of 9.24 cm/px.
  • Validation: Use of the Ironbow palette and DJI Thermal Tool v3 for absolute temperature measurements at an emissivity of 0.95 (bitumen/concrete).

Interactive Digital Twin & Reports

In this project, we go beyond a static report. We deliver an interactive environment where every pixel contains data.
