Immersive representation for visualizing surface temperature and integrative lighting in architecture

This paper illustrates the potential of representing and reading environmental data captured for immersive visualization of indoor built environments. This study introduces methods for qualitative representation of light and heat in aligned viewing directions in immersive scenes. It employs a novel technique for capturing High Dynamic Range (HDR) and thermal images in 360-degree directions. This technique allows visualization of radiant temperature and integrative lighting variations associated with the viewing direction and time. The highlight of these visualizations is the identical viewing points in studying the indoor ambiances. The paper provides visualizations derived from hourly data captures in architectural studios through a 360-degree thermal-visual capturing device. The paper aims to present these results through various visualization formats, including architectural planar presentations, diagrams, and colour maps, showing surface temperature and Photopic and Melanopic illuminance intensities. Architectural insights gained from each of these visualizations are highlighted and discussed. Specifically, the results of this research illustrate the potential of the immersive image-based environmental assessment and visualization method for representing indoor ambiances regarding their non-visible thermal and lighting conditions through time and across all viewing directions within the space. •360° Visual Representations: Presents visual representations of thermal and lighting capture images in 360 directions from mutual viewing points in indoor spaces.•Novel Analytical Approach: Introduces a novel approach for investigating thermal and lighting conditions in indoor environments through temporal analyses.•Integrated Data Visualization: Interpreting multiple data types in single views, aligned with different spatial directions.
