AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
This work reviews existing models of control patterns for occupant-shading interactions in office buildings, and studies their influence in terms of energy demand when comparing transparent façade alternatives. It starts by establishing a review of visual ...
Use of daylight offers great potential benefits in terms of energy savings, visual comfort and health, as long as it is properly controlled. This project is motivated by the necessity to describe façade systems and interior surfaces in order to quantify an ...
This paper presents an investigation of how ModelPredictiveControl (MPC) and weatherpredictions can increase the energy efficiency in Integrated Room Automation (IRA) while respecting occupant comfort. IRA deals with the simultaneous control of heating, ve ...
We describe a reconfigurable lighting system for indoor solar illumination which provides a new way for solar energy conservation. We have experimentally demonstrated an electrically tunable optofluidic light switch which takes the key role for the reconfi ...
The study uses a domestic dwelling as the setting to investigate and explore the applicability of daylighting metrics for residential buildings. The metrics address daylight provision for task and electric lighting usage. In addition to these it also inves ...
This presentation will discuss how recent findings in photobiology about the correlation between lighting and the human circadian system can prospectively be applied to architectural design, with a focus on healthcare and housing environments. Outcomes of ...
Windows are one of the most complex determinants of the office indoor environment and have a significant impact on the overall energy demand for electric lighting, heating and cooling, which typically account for more than 50% and often more than 70% of th ...

Daylight is a dynamic source of illumination in architectural space, creating diverse and ephemeral configurations of light and shadow within the built environment. It can generate contrasting levels of brightness between distinct geometries or it can high ...
In sighted humans, light intensity, timing, exposure duration, and spectral composition of light are important to entrain the endogenous circadian pacemaker to the 24-h day-night cycle. We tested the impact of two realistic office lighting conditions durin ...
This paper investigates the formulation of a modelling framework for the nonvisual effects of daylight, such as entrainment of the circadian system and maintenance of alertness. The body of empirical data from photobiology studies is now sufficient to star ...
