Summary
This study explored whether LED lighting parameters (color temperature and intensity) could offset thermal discomfort in office environments, potentially enabling looser temperature control for energy savings. While direct effects of light on thermal comfort were not statistically significant, correlations between visual and thermal comfort and indirect cross-modal effects were observed.
Key Findings
- Direct effects of light manipulations (color temperature and intensity) on thermal comfort did not reach statistical significance in either the thermoneutral (21°C) or mild cold (17°C) condition.
- Visual comfort and thermal comfort were positively correlated, and indirect cross-modal effects of light on thermal appraisals were observed.
- Experiments were conducted at two temperatures (21°C thermoneutral and 17°C mild cold), with light conditions varied within sessions across separate days.

The Science of Light: Investigates cross-modal interactions between light (color temperature and intensity) and thermal perception via cortical/subcortical pathways.
