“…Although widely discussed, the negative impacts of the introduction of artificial nighttime lighting on human health remain to be fully understood (but see Navara and Nelson 2007;Erren and Reiter 2009;Boyce 2010;Fonken and Nelson 2011). However, there is growing evidence that these impacts may be substantial and quite pervasive, foremost because of the effects of exposure to artificial light at night on melatonin suppression, and its downstream consequences (Lewy 1983;Zeitzer et al 2000).…”

Artificial lighting has transformed the outdoor nighttime environment over large areas, modifying natural cycles of light in terms of timing, wavelength, and distribution. This has had widespread benefits and costs to humankind, impacting on health and wellbeing, vehicle accidents, crime, energy consumption and carbon emissions, aesthetics, and wildlife and ecosystems. Here, we review these effects, particularly in the context of ongoing developments in the extent of artificial lighting and in the prevalent technologies being employed. The key issue that emerges is how best to maximize the benefits of artificial nighttime lighting whilst limiting the costs. To do so, three main strategies are required. First, important knowledge gaps need to be filled. Second, there is an urgent need to connect the research being conducted in different disciplines, which to date has been very disjointed. Third, it is imperative that much firmer and well-developed links are made between research, policy, and practice.Key words: accidents, aesthetics, crime, ecosystems, health, light pollution, lighting, night, sky glow, wellbeing.Résumé : L'éclairage artificiel a transformé l'environnement nocturne extérieur sur de grandes superficies, modifiant les cycles naturels de la lumière en terme de temps, de longueurs d'ondes et de distribution. Ceci s'est traduit par des coûts et bénéfices largement étendus pour l'humanité, affectant la santé et le bien-être, les accidents d'automobile, le crime, la consommation d'énergie et les émissions de carbones, l'esthétique ainsi que la faune et les écosystèmes. Les auteurs passent en revue ces effets, particulièrement dans le contexte de développement continu dans l'extension de l'éclairage artificiel et dans les technologies dominantes mises en oeuvre. La problématique clé qui en émerge consiste à savoir comment maximiser le mieux possible les bénéfices de l'éclairage nocturne artificiel tout en limitant les coûts. Pour atteindre cet objectif, trois stratégies principales s'imposent. Il faut d'abord combler des déficiences de connaissances. Deuxièmement, il existe un urgent besoin d'intégrer les travaux de recherche conduits dans diverses disciplines, lesquels ont été conduits de façon disparate jusqu'ici. Et troisièmement, il est impératif que des liens beaucoup plus solides et mieux développés se développent entre la recherche, les politiques et la pratique. [Traduit par la Redaction]

“…Boyce stated that "shadows" and "veiling reflections" are another two lighting conditions which could also causes physiological discomfort among operators [5]. Shadows occurred when light is intercepted by an opaque object, for instances, a large piece of machinery; hence, casting a shadow in the adjacent areas [5].…”

“…Shadows occurred when light is intercepted by an opaque object, for instances, a large piece of machinery; hence, casting a shadow in the adjacent areas [5]. Veiling reflection is the condition when a source of high luminance light (for example, a luminaire or a window) is reflected from a specularly reflecting surface such as a glossy printed page or a computer screen [5]. All of these working conditions should be avoided to allow the operators to work in a comfortable working condition while simultaneously maintaining physical health and well-being.…”

Abstract. Based on the Market Watch 2012 with regards to the ASEAN region, Malaysia is the third biggest automotive manufacturing nation which employs more than 300,000 people. To accomplish their operation demands, manufacturing companies such as Proton and Perodua would utilize artificial lighting in their respective manufacturing plants. Research on the effects of artificial lighting on human expended about millions of dollars every years. Sufficient lighting is required for effective tasks completion while providing adequate visual capability, thus will ensure the safety of the operators. Eye strain, migraine and headache are among the common symptoms caused by poor lighting at workplace. This study aims to review on prior research regarding sufficient lighting while giving a special focus on light assessment techniques and tools in determining the luminous level in manufacturing plants. This study will contribute to create awareness among the manufacturing plant on the importance of lighting in term of work performance and occupational safety and health.

“…Other studies evaluated shading devices [5], [6], defining the effect of blinds or overhangs, as well as the relationship of these shading devices with electric lighting [7]. Recent studies have investigated whether there is a relationship between the spectrum of daylight and health outcomes [8]. In addition, light reaching the retina has a profound effect on human health and well-being.…”

Abstract-Light is the major synchronizer of circadian rhythms to the 24-hour solar day. Compared to the visual system, the circadian system requires more light to be activated and is more sensitive to short-wavelength light. Daylighting is an ideal light source for circadian entrainment. Architectural and design features, such as window size and room reflectances impact the amount of circadian stimulus that the patient will receive. DaySim 3.2 simulations were used to determine the percentage of days that occupants would receive a minimum circadian stimulation of 0.50 for at least an hour during the morning. According to a phototransduction model of the human circadian system, a circadian stimulation of 0.50 is equivalent to suppressing the hormone melatonin by about 50%. This circadian stimulus criterion is examined for different window to wall ratios, for two average room reflectances, and for four latitudes. The present paper provides an example of a tool that could be used to assist designers in fenestration and interior design.Index Terms-Circadian stimulus, daylight autonomy, visual comfort, window.
