    Abstract

    Light induces not only visual responses but also non - visual effects, indeed it affectsperformance, mood, attention and influences the synchronization of the biological clock. Duration,timing, intensity and the spectral power distribution of the light that reaches the eyes can haveinfluence on human circadian rhythm and consequently on health. Given the important impact of thenon - visual responses on people wellbeing, developing a model that allows lighting designers topredict them is a fundamental goal.In this paper a case study is reported: a series of measurements were carried out in a Universityclassroom in order to study daylight and electric light characteristics and also their impact on thehuman circadian system by calculating melatonin suppression. The results obtained show that not onlythe intensity but also the SPD of the light received by the eyes plays a significant role on circadianresponse and the spectral characteristics of internal and external surfaces influence the SPD andthence the CCT of the light that hits the eyes. Although the working behavior of the human circadiansystem is not completely understood, the results obtained give the designers new points of view tobetter evaluate lighting quality and its implications in indoor environments
