Dynamics of Subjective Thermal Comfort and Skin Temperatures Under Self-Selected (Day-) Lighting Conditions

Jean-Louis Scartezzini, Apiparn Borisuit, Mirjam Münch, Lenka Maierova

2018

Diurnal variations of hormonal secretion, alertness and cognition in extreme chronotypes under different lighting conditions

Jean-Louis Scartezzini, Apiparn Borisuit, Mirjam Münch, Lenka Maierova

Circadian rhythms in physiology and behavior are modulated by external factors such as light or temperature. We studied whether self-selected office lighting during the habitual waking period had a different impact on alertness, cognitive performance and h ...

Monitoring and rendering of visual and photo-biological properties of daylight-redirecting systems

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Anothai Thanachareonkit, Apiparn Borisuit, Mirjam Münch

We previously developed a Camera-Like Light Sensor (CLLS) to record images using a novel High Dynamic Range (HDR) imaging vision sensor. The device was equipped with customized filters for adapting the camera’s spectral sensitivity to both photopic and cir ...

Effects of realistic office daylighting and electric lighting conditions on visual comfort, alertness and mood

Jean-Louis Scartezzini, Friedrich Linhart, Apiparn Borisuit

Lighting conditions in workplaces contribute to a variety of factors related to work satisfaction, productivity and well-being. We tested whether different photometric variables also influence visual perception and the comfort of the lighting, as well as s ...

The Impact of Light Including Non-Image Forming Effects on Visual Comfort

Apiparn Borisuit

Visual comfort at workplaces has often been considered in terms of discomfort glare, luminance distribution and task visibility. Besides visual effects, the lighting environment has also impact on human physiology and behaviour. These effects of light are ...

A new device for dynamic luminance mapping and glare risk assessment in buildings

Laurent Deschamps, Jean-Louis Scartezzini, Apiparn Borisuit

High dynamic range imaging has been shown to be a reliable tool to assess luminance maps and glare risk probability in buildings. However, there are some limitations of image capturing time, especially when dealing with highly dynamic and contrasted daylig ...

Effects of prior light exposure on early evening performance, subjective sleepiness, and hormonal secretion

Jean-Louis Scartezzini, Friedrich Linhart, Apiparn Borisuit, Mirjam Münch

In sighted humans, light intensity, timing, exposure duration, and spectral composition of light are important to entrain the endogenous circadian pacemaker to the 24-h day-night cycle. We tested the impact of two realistic office lighting conditions durin ...

Comparison of objective and subjective visual comfort and associations with non-visual functions in young subjects

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Friedrich Linhart, Apiparn Borisuit, Mirjam Münch

Visual comfort is a key element at work places and at home. Besides task illuminance and color rendering it is the indoor light distribution, which strongly impacts visual comfort. We aimed to show possible relations between subjective and objective visual ...

EPFL2011

Visual Discomfort and Glare Rating Assessment of Integrated Daylighting and Electric Lighting Systems using HDR Imaging Techniques

Jean-Louis Scartezzini, Apiparn Borisuit

The combined integration of daylighting and electric lighting systems within buildings --also designated by the term “Green lighting”, which is a recent issue for the lighting research community-- allows achieving better lighting conditions for building oc ...
