Lighting in educational environments: An example of a complete analysis of the effects of daylight and electric light on occupants
2013
Abstract Light induces not only visual responses but also non-visual effects, indeed it affects performance, 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 have influence on human circadian rhythm and consequently on health. Given the important impact of the non-visual responses on people wellbeing, developing a model that allows lighting designers to predict them is a fundamental goal. In this paper a case study is reported: a series of measurements were carried out in a University classroom in order to study daylight and electric light characteristics and als…
Analisys on the feasibility to modulate lighting systems load: the case study of Palermo
2022
The feasibility to shift and/or modulating the loads that characterize buildings can be useful to improve the performance of smart grids. As known, it is not possible to shift in the time the operating time of the lighting system, but it is possible to modulate the needed electric power. In this paper, the first set of data and a preliminary analysis conducted in the Solarlab of the University of Palermo are presented. The innovative lighting system was designed, sized and installed with the aim of evaluating the consumption of an island user that can be controlled by the DSO or an aggregator. In order to do this, the lighting system load was modulated by applying different strategies: vary…
