Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
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.
To assess the daylighting performances of a building, one of the most commonly used quantities is the Daylight factor, which is defined for a given surface element inside the analysed room as the ratio of the inside and outside illuminances under a CIE ove ...
To describe complex fenestration systems such as novel solar blinds, new glazing or coating materials, daylight and sunlight-redirecting devices, a detailed description of their optical properties is needed, given by their Bidirectional Transmission (or Re ...
The radiant external environment may be described by two hemispheres, above and below the horizontal plane, which are discretised into patches of known solid angle. Occlusions to these patches may be combined and represented as some patch fraction for whic ...
The objective of this paper is to assess the capability of existing lighting simulation methods to predict the performance of complex fenestration systems, which are becoming a commonly used component in buildings construction domain. A specific experiment ...
In this paper, the development of an original and time-efficient measurement device is proposed for the detailed investigation of the daylight distribution within buildings. It is meant to be used for two kinds of applications: - to assess the sunlight dis ...
A new measurement device for the in-depth investigation of the light distribution within buildings is being developed, whose aim is on one hand to assess the sunlight distribution inside scale models of buildings or rooms, and on the other hand to achieve ...
Recent studies have pointed out the general tendency of scale models to overestimate the daylighting performance of buildings, usually expressed through work plane illuminance and daylight factor distribution profiles. An analysis of the corresponding sour ...
To assess the daylighting performances of a building, one of the most commonly used quantities is the Daylight factor, which is defined for a given surface element inside the analysed room as the ratio of the inside and outside illuminances under a CIE ove ...
Among the three components of daylight affecting a surface's illumination inside a room, the direct component, due to light flux reaching the surface element directly from the sky, (also called sky factor) is the most significant one. Its estimation must t ...
An accurate evaluation of daylight distribution through advanced fenestration systems (complex glazing, solar shading systems) requires the knowledge of their Bidirectional light Transmission (Reflection) Distribution Function BT(R)DF. An innovative equipm ...
