Regional Differences in the Perception of Daylit Scenes across Europe Using Virtual Reality. Part II: Effects of Facade and Daylight Pattern Geometry

Marilyne Andersen, Jan Wienold, Kynthia Chamilothori

While there is a growing use of complex facade designs in contemporary architecture worldwide and across Europe, little is known about the perceptual effects of these facades and the resulting daylight patterns on occupants, or about how such effects might ...

Transmittance thresholds of electrochromic glazing to achieve annual low-glare work environments

Marilyne Andersen, Jan Wienold, Sneha Jain

A recent study on the glare protection performance of electrochromic (EC) glazing showed that visible transmittance levels lower than 0.6% are necessary to achieve comfortable situations for sun positions, that were close to the central field of view. Howe ...

Three-dimensional radiative transfer effects on airborne and ground-based trace gas remote sensing

Alexis Berne, Dominik Brunner, Thomas Wagner

Air mass factors (AMFs) are used in passive trace gas remote sensing for converting slant column densities (SCDs) to vertical column densities (VCDs). AMFs are traditionally computed with 1D radiative transfer models assuming horizontally homogeneous condi ...

Window Size Effects on Subjective Impressions of Daylit Spaces: Indoor Studies at High Latitudes Using Virtual Reality

Marilyne Andersen, Jan Wienold, Kynthia Chamilothori

Daylight provision to the indoor space is affected by different building elements that cannot be fully controlled by the users, such as the window size of a space. The dimensions of the fenestration not only affect the lighting levels, but they also affect ...

A new method to determine multi-angular reflectance factor from lightweight multispectral cameras with sky sensor in a target-less workflow applicable to UAV

Manuel Simon Paul Cubero-Castan, Christoph Strecha, Dai Shi

A new physically based method to estimate hemispheric-directional reflectance factor (HDRF) from lightweight multispectral cameras that have a downwelling irradiance sensor is presented. It combines radiometry wilh photogrammetric computer vision to derive ...

Daylight regulated by automated external Venetian blinds based on HDR sky luminance mapping in winter

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Yujie Wu

Automated shading systems have the potential to exploit daylight in buildings to save energy of artificial lighting and cooling loads and improve occupants'f visual comfort. This paper investigates the daylighting performance of automated Venetian blinds b ...

Building Duration / El Portico de los Huespedes

Patricia Guaita, Raffael Baur, Sony Devabhaktuni

El Portico de los Huéspedes is a pedagogical, design-research project that tests the possibility of an open-ended architecture, where duration links between past and future. It is a work of architecture as becoming: ‘work’ meaning the structure, rhythms an ...

On-site monitoring and subjective comfort assessment of a sun shadings and electric lighting controller based on novel High Dynamic Range vision sensors

Jean-Louis Scartezzini, Laurent Deschamps, Ali Motamed

Electric lighting is responsible of about one fifth of the electricity demand of buildings in Switzerland. Therein, integrated control of sun shadings and artificial lighting can mitigate the electricity demand while maintaining the user comfort and perfor ...

On the integration of Non-Image-Forming effects of light on venetian blinds and electric lighting control

Jean-Louis Scartezzini, Laurent Deschamps, Ali Motamed, Marta Benedetti

Light induces important “Non-Image-Forming” (NIF) effects on human physiology and behavior, such as improvement of alertness, cognitive performance and mood. Considering these effects in office lighting can improve well-being and productivity of the occupa ...
