“…Another article recommends 500 lx for general office work and 750 lx for offices with designs that do not allow sunlight as well as drawing jobs that involve color sensitivity and proofreading that require precision [36]. The actual light received by the eye's pupil is lower than the recommendation and yet there were no complaints about the lower illumination [37]. The acceptance of lower illuminance is in accordance with the opinion that the illumination level can be lowered from the recommended standard because workers can still carry out their activities with lighting below 350 lx [38].…”

Lighting in the workplace is often assessed based on functionality. In line with scientific development, the research into lighting observes its effect on the occupant's health and psychology. This article discusses research publications related to the relationship between artificial lighting and mood, by reviewing relevant literature from journals, dissertations, theses, and books from the last 10 years. Some of the literature refers to the older sources; hence the study is expanded to cover, in certain cases, a publication period of more than 10 years ago. The first section of this review discusses the general definition of mood and its role in the workplace. The next section explains the visual requirements of a workplace environment, especially regarding the required standards and the lighting's effects on health. The third section of the paper discusses the relationship between the visual environment and mood, with particular reference to how lighting enters and affects mood. The final section of this discussion addresses previous research related to the visual environment and mood that can be categorized into three focal points: (i) illuminance level effects; (ii) correlated color temperature effect, and (iii) mixed influencing factors.

“…Then, it was used an equation proposed by Jacobs (Jacobs, 2014) Finally, through a calibration process, the Yrel values were transformed using a conversion factor using the illuminance values measured by the reference illuminance meter . More details about this process can be seen in (Dias et al, 2017;2019).…”

Throughout the 20th-century lighting systems designed for office buildings have focused mainly on the amount of light needed for work, based on visual criteria: illuminance in the horizontal plane was the most important design objective while non-visual biological effects were not considered. This paper presents a research carried out at LESO solar experimental building at EPFL (Lausanne, Switzerland), designed to investigate how light flux reaches the user's eyes. During 5 full days in January 2017, two young females with normal vision used each one a wearable device named OcuLux, which has an RGB sensor attached to the glass frames for registering continuously the actual pupilar illuminance (lux). At the end of each day the participants answered an online questionnaire based on Office Lighting Survey. Relative position of participants implies in different light doses. Qualitative and quantitative data were important to understand how light reaches the humans eyes.

Los efectos de iluminación natural en espacios interiores tienen una notable influencia sobre el ambiente de la edificación, pero más aún, en el bienestar del usuario. El objetivo de este estudio fue analizar la iluminación natural y el cumplimiento del rango de iluminación de 300 lux que la NOM-025-STPS-2008 establece como óptimo, mismo que estándares internacionales consideran como mínimo. Se realizó un diagnóstico ambiental y energético a partir del simulador Design Builder, se analizó una oficina del sector privado situada en clima cálido seco extremoso, así mismo, se estudiaron cinco escenarios de cielo distintos: un día de cielo nublado y cuatro días representativos de cielo claro. El análisis para identificar la iluminación natural se determinó a partir del Factor Luz Día expresado en lux. Se establecieron deficiencias o excesos de calidad de iluminación a partir de los resultados del caso base, además, se simularon otros nueve escenarios con diferentes sistemas de acristalamiento con el fin de analizar los efector sobre ganancias de calor. Las propiedades del material que permiten un mejor comportamiento térmico y lumínico son aquellos con menor coeficiente por ganancias de calor solar y mayor coeficiente visible térmico. El mejor sistema de acristalamiento se encuentra con un doble ultra claro, al mantener la iluminación solo 5% por debajo que el caso base y disminuir el 18% las ganancias de calor por acristalamiento. La mejor condición termo-energética fue con un vidrio sencillo tinte azul turquesa ya que a pesar de disminuir en 25% la iluminación, permitió cumplir con la norma mexicana y disminuir en 55% las ganancias de calor. Se requiere continuar el estudio y modificar la relación ventana-suelo y ventana-muro, así como la forma y ubicación del vano para establecer si realmente el vidrio sencillo tintado es mejor que los sistemas de acristalamiento doble.
