“…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.
