Virtual reality to assess visual attraction and perceived interest to daylit scene variations

Marilyne Andersen, Caroline Karmann, Bahar Aydemir, Kynthia Chamilothori

Façades and light pattern composition have been shown to influence the spatial experience and physiological responses of humans [1,2]. The present study examines the effect of sunlight penetration and window size on fixations to the floor of the scene, and ...

Behind electrochromic glazing: Assessing user's perception of glare from the sun in a controlled environment

Jan Wienold, Caroline Karmann, Sneha Jain

The adaptable transmittance of electrochromic glazing allows to control the solar radiation entering buildings, yet the level of transmittance needed to protect from glare is still an unanswered question. To bridge this gap, this study evaluates the level ...

Influence of indoor temperature and daylight illuminance on visual perception

Marilyne Andersen, Jan Wienold, Giorgia Chinazzo

This paper details the results of an experimental study investigating the combined effect of indoor temperature (19 ℃, 23 ℃ and 27 ℃) and horizontal illuminances (∼140 lx, ∼610 lx and ∼1440 lx) on visual perception, with daylight as the only source of ligh ...

A smart luminaire in an office environment: impact on light distribution, user interactions and comfort

Jérôme Henri Kämpf

A smart luminaire able to change the direction of its light beam is installed in an office environment and compared to the available LEDs fixtures. Standard lighting measures are performed and a controlled user experiment is conducted, involving 22 subject ...

Daylighting simulation for external Venetian blinds based on HDR sky luminance monitoring with matrix algebraic approach

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Yujie Wu

An accurate daylighting simulation can potentially improve the quality of pre-planing buildings and regulating daylighting to achieve the goal of green buildings. However, standard sky models can hardly reproduce real skies in real-time for a specific loca ...

Sky Monitoring System

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Yujie Wu

In a sky monitoring system (S), comprising an image sensor (1), a wide angle lens (16), a microprocessor (3), and a memory unit (11, 18), wherein the sky monitoring system (S) is configured to take pictures of a sky scene, wherein the sky monitoring system ...

A field study investigation on the influence of light level on subjective thermal perception in different seasons

Marilyne Andersen, Jan Wienold, Luisa Pastore, Giorgia Chinazzo

This paper evaluates the influence of light levels (i.e., illuminance) on subjective thermal perception of people, distinguishing between thermal sensation and thermal evaluation. The goal is to investigate whether reported effects found by other studies i ...

Lighting simulation for External Venetian blinds based on BTDF and HDR sky luminance monitoring

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Yujie Wu

The precise daylighting simulation in buildings can potentially contribute to designers’ and occupants’ smart utilization of it. The traditional method of employing sky models was indicated with noticeable errors in transient lighting simulation for comple ...
