Characterization of wind turbine flow through nacelle-mounted lidars: a review
Fernando Porté Agel, Peter Andreas Brugger
This article provides a comprehensive review of the most recent advances in the planning, execution, and analysis of inflow and wake measurements from nacelle-mounted wind Doppler lidars. Lidars installed on top of wind turbines provide a holistic view of ...
2023Discomfort glare from daylight: Influence of transmitted color and the eye's macular pigment
Designing architectural façades that allow sufficient daylight to create visually comfortable and pleasantenvironments is a challenging aspect of building design. It requires accounting for visual comfort anddiscomfort glare risks and understanding the fac ...
EPFL2023Comparison of questionnaire items for discomfort glare studies in daylit spaces
Marilyne Andersen, Jan Wienold, Caroline Karmann, Sneha Jain, Geraldine Cai Ting Quek, Clotilde Marie A Pierson
When studying discomfort glare, researchers tend to rely on a single questionnaire item to obtain user evaluations. It is unclear whether the choice of questionnaire item affects the distribution of user responses and leads to inconsistencies between studi ...
2023An experimental and analytical study of wind turbine wakes under pressure gradient
Fernando Porté Agel, Arslan Salim Dar, Abraham Starbuck Gertler
This work is dedicated to the systematic investigation of wind turbine wakes under the effect of pressure gradients. Wind tunnel experiments are carried out with a wind turbine positioned on straight ramps of increasing angle such that it experiences an ap ...
2023Discomfort glare from daylight: Influence of transmitted color and the eye's macular pigment
Designing architectural façades that allow sufficient daylight to create visually comfortable and pleasant environments is a challenging aspect of building design as it requires to account for visual comfort and discomfort glare risks, and understand the f ...
2023IS THERE AN EFFECT OF MACULAR PIGMENT DENSITY ON DISCOMFORT GLARE IN INDOOR DAYLIGHT CONDITIONS?
Marilyne Andersen, Jan Wienold, Caroline Karmann, Sneha Jain
Discomfort glare from daylight can lower productivity and hinder effective use of daylight in buildings. Existing glare prediction models have limitations in accounting for the large inter-individual differences, mainly due to unknown physiological factors ...
International Commission on Illumination2023Influence of macular pigment on the sensitivity to discomfort glare from daylight
Marilyne Andersen, Jan Wienold, Sneha Jain
Understanding the factors that influence the human perception of glare is necessary to properly address glare risks in buildings and achieve comfortable visual environments, especially in the workplace. Yet large inter-individual variabilities in glare per ...
2023Preliminary evidence that daily light exposure enhances the antibody response to influenza vaccination in patients with dementia
Enhancing lighting conditions in institutions for individuals with dementia improves their sleep, circadian rhythms and well-being. Here, we report first findings that exposure to brighter light during daytime may support the immune response to the annual ...
ELSEVIER2022Optimized office lighting advances melatonin phase and peripheral heat loss prior bedtime
Jean-Louis Scartezzini, Mirjam Münch, Marta Benedetti, Lenka Maierova
Improving indoor lighting conditions at the workplace has the potential to support proper circadian entrainment of hormonal rhythms, sleep, and well-being. We tested the effects of optimized dynamic daylight and electric lighting on circadian phase of mela ...
2022Genetic selection for low glucocorticoid responsiveness recapitulates PTSD-related phenotypes: a behavioral, neuroimaging and sleep-physiology study
Humans show inter-individual differences in vulnerability to develop post-traumatic stress disorder (PTSD) following exposure to trauma. Several critical biobehavioral features have been consistently described in PTSD patients, including blunted cortisol l ...
