Evening office lighting - visual comfort vs. energy efficiency vs. performance?

Jean-Louis Scartezzini, Friedrich Linhart

During the study presented in this article, we compared two highly energy-efficient lighting scenarios for evening office lighting (i.e. electric lighting that is typically used for approxiamately 2 h in the evening). The first of these lighting scenarios ...

A Novel Louver System for Increasing Daylight Usage in Buildings

Marilyne Andersen

Advanced daylighting systems can be effective in increasing light levels in building spaces and reducing energy consumption due to electric lighting. However, a recurring issue found in most existing daylighting systems is the necessity of coupling the lig ...

Advanced Window and Lighting Technologies in net Zero Energy Buildings

Jean-Louis Scartezzini

Light has an important visual and non-visual impact on humans. Most of our information exchange, especially within office working spaces, occurs through it, our circadian rhythms are directly influenced by its presence. On the other hand, artificial lighti ...

Towards a refined understanding of comfort in workspaces

Marilyne Andersen, Mandana Sarey Khanie

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 ...

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 ...

Visual Discomfort and Glare Rating Assessment of Integrated Daylighting and Electric Lighting Systems using HDR Imaging Techniques

Jean-Louis Scartezzini, Apiparn Borisuit

The combined integration of daylighting and electric lighting systems within buildings --also designated by the term “Green lighting”, which is a recent issue for the lighting research community-- allows achieving better lighting conditions for building oc ...

Energetic, Visual and Non-Visual Aspects of Office Lighting

Friedrich Linhart

Light has important visual and non-visual effects on humans and high-quality light should therefore be supplied inside buildings in sufficient quantities. On the other hand, artificial lighting is responsible for a large part of an office building's electr ...

Increasing energy efficiency in building climate control using weather forecasts and model predictive control

Colin Neil Jones

This paper presents an investigation of how Model Predictive Control (MPC) and weather predictions can increase the energy efficiency in Integrated Room Automation (IRA) while respecting occupant comfort. IRA deals with the simultaneous control of heating, ...

Exploiting redundancy in color images

Joanna Marguier

The colors in a digital image do not only depend on the scene's reflectances, but also on the lighting conditions and on the characteristics of the imaging device. It is often necessary to separate the influence of these three elements, in particular to se ...
