Graph Chatbot
Chattez avec Graph Search
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.
Because of the longevity of the built environment, it is important not only to study methods of daylighting in new buildings, but to consider daylighting in existing buildings as well. Technologies exist which could benefit these buildings, but predicting ...
Electric lighting is responsible for a significant fraction of electricity consumption within non-residential buildings. Making daylight more available in office and commercial buildings can lead as a consequence to important electricity savings, as well a ...

This paper describes how data collected during a continuously running data acquisition program on the LESO building in Lausanne, Switzerland, was used to measure the intermediate light switch probability by users as a function of current illuminance levels ...
This work takes benefit from two advanced building technologies through the integration of an anidolic daylighting system and an electro-chromic glazing in a building facade for achieving an optimal control of the daylight flux entering in an office room. ...
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 ...
The “Green Lighting” research project, initiated at the Solar Energy and Building Physics Laboratory (LESO-PB) of the Swiss Federal Institute of Technology in Lausanne (EPFL), is aiming at an energy efficient integration of advanced daylighting and electri ...
We propose a self-commissioning, user-adaptive blinds and electric lighting controller for small office rooms. Self-commissioning, in this context, means that the controller builds an internal representation of the room, in particular of the room's dayligh ...
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 ...
ABSTRACT : The Energy Performance of Buildings Directive (EPBD) requires EU member states to establish a methodology for calculating the energy performance of buildings within a framework that includes the effect of active and passive solar systems as well ...
La protection de l’environnement fait aujourd’hui partie des préoccupations majeures de notre société ; dans ce contexte, la nécessité de réduire la consommation énergétique dans le bâtiment se place comme une priorité. Dans le domaine de l’éclairage, et p ...
