Exploring the Interplay between Thermal and Visual Perception: A Critical Review of Studies from 1926 to 2022

Links

Summary

This critical review spanning 1926–2022 examines how visual and thermal perception interact, finding that lighting color (the 'hue-heat' hypothesis) can influence perceived warmth or coolness under specific experimental conditions. Practical implications suggest that tunable lighting strategies could be used to modulate perceived thermal comfort, potentially reducing energy consumption while maintaining occupant wellbeing.

Key Findings

The 'hue-heat' hypothesis (warm-colored light perceived as warmer, cool-colored light as cooler) is verified under specific experimental conditions that allow measurement of subtle parameter variations.
The review covers nearly a century of research (1926–2022), identifying both advances and remaining scientific hurdles in quantifying thermo-photometric perception interactions.
Findings suggest potential for lighting design to complement thermal systems in buildings, with energy performance and occupant wellbeing implications, though effect sizes and magnitudes remain context-dependent.
