Towards a refined understanding of comfort in workspaces

This interdisciplinary research aims at addressing a question common to the fields of architecture, building technology and psychophysics: are there objective relationships between perceived comfort, occupant response patterns and lighting conditions? The ...

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

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

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 ...

Daylight optimization of buildings and application of advanced daylighting systems in Central Mexico

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Mirjam Münch, Apiparn Borisuit, Chantal Basurto Dávila

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 ...

Daylighting Metrics for Residential Buildings

Marilyne Andersen, Nicolas Roy

It is now widely accepted that the standard method for daylighting evaluation - the daylight factor – is due for replacement with metrics founded on absolute values for luminous quantities predicted over the course of a full year using sun and sky conditio ...

Engineering photonic nanojets

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

Photonic Nanojets are highly localized wave fields emerging directly behind dielectric microspheres; if suitably illuminated. In this contribution we reveal how different illumination conditions can be used to engineer the photonic Nanojets by measuring th ...

Ray-tracing simulation of complex fenestration systems based on digitally processed BTDF data

Jean-Louis Scartezzini, Jérôme Henri Kämpf

The implementation of Complex Fenestration Systems (CFS) in the day-to-day life by practitioners, such as lighting designers, architects and façade makers is not an easy task. However, computer design tools can reinforce their usage through the determinati ...

Towards a model for View Direction patterns as a function of light distribution

Mandana Sarey Khanie

DAYLIGHT is a desirable architectural component that satisfies both visual and psychological needs of the occupants. Therefore it is essential to integrate this component in the design in a way that maximum daylight is guaranteed and a visually healthy and ...

Climate-based Daylight Performance: Balancing Visual and Non-visual Aspects of Light Input

Marilyne Andersen, Nicolas Roy

This study uses a domestic dwelling as the setting to investigate and explore the applicability of daylighting metrics for residential buildings, including the formulation of metrics for nonvisual effects. The simulation approach used to generate the perfo ...
