Perceived and yet not seen: non-visual effects in daylit spaces
Marilyne Andersen, Forrest Simon Webler, Victoria Eugenia Soto Magán
Findings from neuroscience are increasingly interwoven with architectural research (1,2). Understanding physiological responses to environmental stimuli in the built environment is critical when evaluating occupant health and wellbeing. Research in the fie ...
2018EPFL Smart Glass Field Study
Marilyne Andersen, Forrest Simon Webler, Victoria Eugenia Soto Magán
The objectives of this study are to evaluate (1) direct non-visual effects of red-impoverished daylight on circadian resetting and alertness and (2) the daily light-exposure pattern on indirect–circadian–effects. The novelty of this study is that it will b ...
KARGER2018Bright Light Delights: Effects of Daily Light Exposure on Emotions, Rest-activity Cycles, Sleep and Melatonin Secretion in Severely Demented Patients
Objective: We tested whether the effects of a dynamic lighting system are superior to conventional lighting on emotions, agitation behaviour, quality of life, melatonin secretion and circadian restactivity cycles in severely demented patients. As a compari ...
Bentham Science Publ Ltd2017High light intensity mediates a shift from allochthonous to autochthonous carbon use in phototrophic stream biofilms
Tom Ian Battin, Amber Joy Ulseth
Changes in the riparian vegetation along stream channels, diurnal light availability, and longitudinal fluctuations in the local light regime in streams influence primary production and carbon (C) cycling in benthic stream biofilms. To investigate the infl ...
Amer Geophysical Union2017Diurnal variations of hormonal secretion, alertness and cognition in extreme chronotypes under different lighting conditions
Jean-Louis Scartezzini, Mirjam Münch, Apiparn Borisuit, 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 ...
Nature Publishing Group2016Light-driven model for identifying indicators of non-visual health potential in the built environment
This thesis introduces a new approach to characterize and evaluate ocular light exposure based on the discovery of novel blue light-sensitive photoreceptors in the human eye. These photoreceptors are the primary mediators of 'non-visual' responses impactin ...
EPFL2016Implications of the interplay between light and dark for human health in the built environment
Marilyne Andersen, María Lovísa Ámundadóttir
24-hour cycles of light and dark are one of the most significant factors in the built environment that affect human health and wellbeing. In addition to stimulating visual responses, light induces a range of circadian, physiological and behavioral response ...
2015Light-Syntax Zones in Daylit Café Spaces: A Novel Method for Understanding Occupancy
This thesis proposes a novel method for understanding occupancy in public indoor spaces by creating hybrid light-syntax zones, based on both simulated illuminance data and simulated configuration data. Yearly illuminance profiles and spatial syntax charact ...
2014Assessment of Circadian Weighted Radiance Distribution Using a Camera-Like Light Sensor
Jean-Louis Scartezzini, Jérôme Henri Kämpf, Laurent Deschamps, Mirjam Münch, Apiparn Borisuit
Suboptimal light distribution in a room can cause visual discomfort and glare. Next to rods and cones, perception of light is also governed by a third class of photoreceptors, important for circadian rhythm regulation and non-visual functions such as alert ...
EPFL Solar Energy and Building Physics Laboratory (LESO-PB)2013The Impact of Light Including Non-Image Forming Effects on Visual Comfort
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 ...
