Healthy lighting: integrating non-visual responses to light into building simulation

María Lovísa Ámundadóttir

The goal of this thesis is to develop a computer-based lighting simulation framework capable of predicting human non-visual responses to light and to validate novel guidelines that can inform designers about how lighting might affect human non-visual respo ...

Significance of View Direction in Simulating Circadian Potential of Architectural Spaces

Sharon Jane Gochenour

This research paper aims to simplify the question of how to take human movement into account when assessing the lighting conditions of a space. For a person working at a desk throughout the day doing paper-based or screen-based tasks, if it is assumed that ...

Lighting and human needs in built spaces

Marilyne Andersen

This presentation will discuss how recent findings in photobiology about the correlation between lighting and the human circadian system can prospectively be applied to architectural design, with a focus on healthcare and housing environments. Outcomes of ...

Environmental light synchronizes the primary mammalian biological clock in the suprachiasmatic nuclei, as well as many peripheral clocks in tissues and cells, to the solar 24-hour day. Light is the strongest synchronizing agent (zeitgeber) for the circadia ...

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

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

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 ...

Circadian and Wake-Dependent Effects on the Pupil Light Reflex in Response to Narrow-Bandwidth Light Pulses

Lorette Leon

PURPOSE. Nonvisual light-dependent functions in humans are conveyed mainly by intrinsically photosensitive retinal ganglion cells, which express melanopsin as photopigment. We aimed to identify the effects of circadian phase and sleepiness across 24 hours ...

Association for Research in Vision and Ophthalmology2012

Evening bright light exposure is reported to ameliorate daytime sleepiness and age-related sleep complaints, and also delays the timing of circadian rhythms. We tested whether evening light exposure given to older adults with sleep–wake complaints would de ...

Daylight – visual comfort and non-visual functions

Mirjam Münch

Within the last decades it became evident that light through the eyes is essential for both visual and non-visual functions. One of the most important non-visual functions of light is the daily entrainment of the circadian clock by environmental light cond ...

The intensive use of daylight in buildings is beneficial at many levels: it provides sufficient levels of illumination to perform working activities throughout the day and it reduces the use of artificial light, which in turn leads to lower electricity con ...

EPFL2011

The circadian rhythms of melatonin and body temperature are set to an earlier hour in women than in men, even when the women and men maintain nearly identical and consistent bedtimes and wake times. Moreover, women tend to wake up earlier than men and exhi ...
