Modeling specular transmission of complex fenestration systems with data-driven BSDFs

A Bidirectional Scattering Distribution Function (BSDF) describes how light from each incident direction is scattered (reflected and transmitted) by a simple or composite surface, such as a window shade. Compact, tabular BSDFs may be derived via interpolat ...

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 ...

A solar-based sustainable urban design: The effects of city-scale street-canyon geometry on solar access in Geneva, Switzerland

Jean-Louis Scartezzini, Dan Assouline, Jérôme Henri Kämpf, Nahid Mohajeri Pour Rayeni

Buildings commonly have the largest share in the energy demand of a country, but they also offer sites for the generation of solar energy. Here we develop a methodology to analyse the effects of street-canyon geometries on the solar access of street surfac ...

Façade design and our experience of space: the joint impact of architecture and daylight on human perception and physiological responses

Marilyne Andersen, Jan Wienold, Kynthia Chamilothori

Daylight has an undeniable value in various aspects of architectural design, ranging from energy efficiency and user comfort to our experience of space. Even though there is substantial evidence of the positive effects of daylight access on occupants, we h ...

Suitability of neighborhood-scale massing models for daylight performance evaluation

Marilyne Andersen, Luisa Pastore, Minu Agarwal

Access to daylight in buildings is the combined effect of a building’s own physical attributes along with its surrounding physical context. There is thus growing interest among researchers to extend the use of building performance simulation (BPS) tools fo ...

Reactively Sputtered Nano-Structured Multilayer Coatings on Architectural Glazing for Active Solar Energy Façades

Stefan Mertin

Improving the aesthetic of solar thermal collectors would grant architects a huge potential for a perfect integration of solar panels into building façades: this can be achieved by coloured interference coatings on the cover glass. These coatings also open ...

Bringing colours to solar collectors: a contribution to an increased building "integrability"

Andreas Schueler, Christian Roecker, Maria Cristina Munari Probst

One main obstacle to facade integration of solar thermal collectors lies in the formal characteristics and low flexibility of available products. Major problems are the black and irregular appearance of their absorbers, their low dimensional flexibility an ...

Nanostructured Coatings on Glazing for Active Solar Facades

Jean-Louis Scartezzini, Christian Roecker, Maria Cristina Munari Probst, Estelle De Chambrier, Josef Andreas Schuler, Dipanwita Dutta

Thin films on glazing play an important role in the design of solar energy conversion systems as thermal collectors or photovoltaic panels. Antireflective coatings based on porous silicon dioxide are well established in the field of solar collector glazing ...

Optimisation of Buildings Daylight Availability

Jérôme Henri Kämpf, Darren Robinson, Marylène Montavon

Many researchers have the goal of improving buildings daylight availability in order to decrease the HVAC energy intake. Indeed by achieving/identifying sustainable urban forms and their design concepts, the benefits of the solar radiation can be of threef ...
