A dataset from a coordinated multi-site laboratory study investigating the Hue-Heat-Hypothesis.

Area of Science:

• Environmental Psychology
• Building Science
• Human-Computer Interaction

Background:

• Cross-modal perception links environmental factors to human experience.
• Occupant well-being and human-centric design require understanding these links.
• The Hue-Heat Hypothesis (HHH) suggests light color impacts thermal perception.

Purpose of the Study:

• To create and share a multi-site database for testing the Hue-Heat Hypothesis (HHH).
• To enable research on how light hue affects thermal perception in diverse environments.
• To support the development of human-centric building design strategies.

Main Methods:

• Developed an open-access, multi-site database under the IEA-EBC Annex 79 project.
• Conducted 543 experimental rounds across eight laboratories in six countries.
• Exposed participants to controlled thermal conditions with varied lighting (neutral, reddish, bluish) and collected physiological and perceptual data.

Main Results:

• The database provides comprehensive data on environmental variables, physiological responses (heart rate, skin temperature), and subjective perceptions.
• Standardized protocols and technical documentation ensure data comparability across sites.
• The collected data allows for robust analysis of the Hue-Heat Hypothesis.

Conclusions:

• The developed database is a valuable resource for investigating cross-modal environmental perception.
• Findings support the potential influence of light hue on thermal comfort.
• This research facilitates advancements in understanding multi-domain human comfort and physiological reactions in buildings.
