Studies have shown that daylighting may play a relevant role both in terms of light and thermal perception of the built environment, and in complex physiological mechanisms not related to vision. These include secretion of hormones linked to the regulation of sleep-wake cycles and body thermal homeostasis. The present study aims to explore relationships between different lighting characteristics of a test-environment and changes in skin surface temperature (Tsk) of male subjects. Correlations between light-related variables measured for different configurations of light sources (natural equatorial, non-equatorial and electrical) and Tsk of 16 participants have been analyzed. Data were gathered in the LOBSTER climate chamber, at the Karlsruher Institut für Technologie (KIT), located in Karlsruhe, Germany. Five-hour sessions took place inside the chamber and under thermally controlled conditions over 36 winter, spring and summer periods. Measured Tsk were found to be strongly related to light variables and such relationship will depend on the availability of daylight. The collected Tsk data showed a significant correlation with tested ambient lighting, and the relationship is directly linked to the availability of natural light. Electric lighting environments without configuration changes, in turn, possibly lead to circadian interruptions. The study resultsfrom an ongoing Post-Doctorateresearch.
