A critical comparison of methods to estimate solar rooftop photovoltaic potential in Switzerland
Jean-Louis Scartezzini, Nahid Mohajeri Pour Rayeni, Alina Ursula Rosa Walch
To understand the opportunities and challenges of large shares of solar photovoltaics (PV) in our electricity mix, various large-scale studies of PV potential on building roofs have been conducted in recent years. The use of different datasets, methods and ...
2019Automated Daylighting Control System based on Sky Luminance Monitoring and Lighting Computing
Sufficient daylight exposure contributes to occupants' productivity and health in buildings. However, excessive daylight ingress induces discomfort glare and increases the cooling load in warm seasons. The performance of manual shading systems is limited b ...
EPFL2019Sampling the Multiple Facets of Light
The theme of this thesis revolves around three important manifestations of light, namely its corpuscular, wave and electromagnetic nature. Our goal is to exploit these principles to analyze, design and build imaging modalities by developing new signal proc ...
EPFL2018Annual glare evaluation for fabrics
Marilyne Andersen, Jan Wienold
Although fabrics are widely used as shading devices, reliable simulation models are rather rare and therefore the choice of a fabric with appropriate material characteristics is difficult. This paper presents a simulation model, which can be applied to mos ...
2017Smooth Shapes with Spherical Topology: Beyond Traditional Modeling, Efficient Deformation, and Interaction
Michaël Unser, Pablo Garcia-Amorena Garcia, Daniel Andreas Schmitter
Existing shape models with spherical topology are typically designed either in the discrete domain using interpolating polygon meshes or in the continuous domain using smooth but non-interpolating schemes such as subdivision or NURBS. Both polygon models a ...
2017Characterization of a quasi-real-time lighting computing system based on HDR imaging
Jean-Louis Scartezzini, Yujie Wu
In this paper we present the characterization of a calibrated embedded system for quasi real-time lighting computation based on HDR sky monitoring. To quantify its accuracy in lighting computation, we positioned the device in front of a test module with un ...
Elsevier2017On 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 ...
Elsevier2017On-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 ...
