Abstract-Studies show that the quality of the school environment significantly influences students' academic performance. Among the many attributes of the school environment, light is one of the most visible and talked about ones. Lighting in the classrooms has been the subject of many studies for over a century. In recent years, special attention has been given to the impact of natural light on learning as light has physiological, psychological and behavioral influences on school children as well as workers. A multitude of surveys has indicated also that daylight impacts the health. We believe that workers' and students' health, satisfaction, attention, and consequently performance are improved with the help of natural light. This paper discusses the current literature and design-based evidence to evaluate the impacts of natural light on office workers and students' scholastic performance. Issues of timing and exposure to daylight are also discussed.Keywords-Daylighting, Morning Sunlight, Students, Health, Workers Performance, Alertness I. INTRODUCTIONAmong the many elements that impact building occupants, lighting seems to have the most influence. Light is an essence for humans and it is known that has physical, physiological, and psychological influences [1].In the early part of the 20 th century, natural light was the primary source of building illumination. In a short span of a couple of decades, electric lighting became the primary source of illumination, mostly because of convenience. In recent years, energy conservation and environmental concerns have changed those practices and brought daylighting once again at the forefront of the sustainability debate [2]. For decades, an appropriate lighting design was based on the idea that it should meet the needs of the building occupants especially in terms of visual task performance. However, recent connections between health and wellbeing and lighting have made lighting of building interiors one of the most salient environmental factors in architectural design [1]. Recent studies have proven that there is a correlation between lighting and humans' performance and health. Light does not only provide visual information but also constitutes a powerful modulator of our circadian rhythm and many non-visual functions including the state of alertness, mental focus, and cognitive performance [3]. Light is also an important ingredient in educational settings, as it appears to have strong influences on cognition and learning. Research on electric lighting in classrooms has received some attention over the last few decades but research on the impact of natural light on students has been somewhat scarce [4]. The limited number of studies in this area seem to show that windows and daylight can enhance students' physical and psychological health, influence their mood, behavior and learning [5], [6]. Our study presents a comprehensive review of recent work that explored the relationship between daylight and students' and workers' health and performance. In this regard, the in...

“…Improvements in subjective alertness, performance and well-being have been shown in office workers20 21 and school children22 exposed to blue-enriched polychromatic lighting during the day . The current study aimed to compare the effects of blue-enriched polychromatic light on alertness and neurobehavioural performance during a laboratory-controlled simulation in night shift workers.…”

“…These carefully done initial studies, however, were limited in that they examined only the acute neuroendocrine effects of relatively intense polychromatic light sources. We built on these results to examine both acute and circadian neuroendocrine responses as well as neurobehavioral differences using a standard light source at more common lower room illuminances In addition to highly controlled laboratory studies, several real-world applications in schools and offices using both static and dynamic lighting manipulations involving blueenriched light have demonstrated increased subjective measures of alertness and affect as well as improvements in standard tests of cognitive processing speed, concentration and reading ability in blue-enriched lighting conditions [23,24,25,26,27]. For example, office installation of the fluorescent lamps used in this study on two floors with participants being exposed in a counter-balanced order resulted in statistically significant improvements in self-reported measures of alertness, mood, performance, evening fatigue, irritability, concentration and eye discomfort during the month of 17000 K exposure as compared to 4000 K [23].…”
