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.
Concern for the environment has been steadily growing in recent years, and it is becoming more common to include environmental impact and pollution costs in the design problem along with construction, investment and operating costs. To economically respond ...

In the urban areas of Europe and USA, a significant part of the final energy consumption corresponds to the buildings heat demand. Given the challenges related to climate change, to energy security and dependency from fossil fuels, modifications of the ene ...
The Lucerne University of Applied Sciences has been analysing and monitoring the low- temperature district heating and cooling network (LTN) “Suurstoffi” since 2012. The analysis showed that heating demand was twice as high as expected. On the other hand, ...
In the framework of the GEOTHERM II, a joint effort of geoscience, engineering and social-science of academic and public partners, the integration of geothermal energy in urban systems is evaluated. A superstructure was defined for the case study of the ci ...
District energy systems have the potential to decrease the CO2 emissions linked to energy services (heating, hot water, cooling and electricity), thanks to the implementation of large polygeneration energy conversion technologies, connected to a group of b ...
A thermo-economic and environomic analysis for the integration of district heating in several power plants using carbon capture and sequestration is done. Variable district heating temperatures have been studied by evaluating the energetic and economic per ...
Nowadays, one of the main alternatives for a more rational use of energy in heating applications is the heat pumping technologies. The market is dominated by two kinds of heat pump systems: the electrically driven vapor compression heat pumps (EHP), which ...
Throughout the years LENI-EPFL spent a significant part of its research activities on heat pumps be it for industrial heat recovery or for domestic or district heating and cooling. Methodological contributions include the improvement of the formulation of ...
Extending the idea of exergy to practitioners and policy makers is still a major challenge. Recently the "Canton of Geneva" in Switzerland introduced a new law governing the procedures of attribution of building permits for new or retrofitted city areas. A ...
