Systematic review: Acute thermal effects of artificial light in the daytime

The acute thermal effects of artificial light during the daytime have potential to promote energy savings and enhance indoor comfort. Although long-held hue-heat hypothesis suggests that visual features lighting may alter human responses, there currently exists no systematic review or cross-study analysis synthesizes characterizes light's impact along both non-visual pathways daytime. This highlights evidence physiological psychological measures examining presence daytime, as obtained from literature. searched articles PubMed, Scopus, Web Science, other sources screened for with thorough information microclimatic conditions describing experiments conducted using static light. Eighteen 18 studies were selected based on inclusion criteria; these featured different experimental intervention designs environment measurements psychological, physiological, behavioral responses. research specifically reviews settings in terms characteristics also identifies effective appropriate effects. Much literature described this exposure is associated thermal-related responses; results across showed statistically significant associations certain (e.g., sensation, preferred temperature) proximal skin temperature, heart rate variability). However, some limited by unavailability key reports lighting, conditions, and/or responses possibly high levels heterogeneity. In general, findings will facilitate continuing advances area, providing more comprehensive scientific rationales strategies adopting smart technologies sustainable buildings.
