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.
Rapid urbanization in recent years has exerted tremendous pressure on urban development. In the face of the largely unexamined fashion for densification, it is vital that the environmental impact of compaction be researched. This study comprises solar simu ...
From a sustainable development perspective, the newly developed automatic controllers for building services are very promising in that they increase energy efficiency and reduce commissioning and maintenance costs. But a major problem has appeared as the a ...
Dynamic simulation is an accurate but time-consuming way tu calculate energy and thermal comfort performances of passive solar buildings. Simplified methods, originally developed to evercome their disadvantage, unfortunately do not provide the same quantit ...
The characteristics of the 'Green Heating System', synonymous with 'Environmentally Friendly Heating System', is academically defined from the total energy systems' point of view, using the concept of 'reversible mode of heating' under the current and futu ...
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 ...
The paper describes a predictive and adaptive heating controller, using artificial neural networks to allow the adaptation of the control model to the real conditions (climate, building characteristics, user's behaviour). The controller algorithm has been ...
The efficient thermal control of buildings is a complex problem. Non controlled perturbations like user behaviour and meteorological conditions can change much with time and make this task difficult. This work proposes considering the building as a 'living ...
Using control theory, apredictive thermal regulation of the "certainty equivalence" type has been developped. Stochastic models of hourly solar rediation and outdoor air temperature, based on the theory of Markov and ARMA processes, were set up for this pu ...
Automated shading systems have the potential to exploit daylight in buildings to save energy of artificial lighting and cooling loads and improve occupants'f visual comfort. This paper investigates the daylighting performance of automated Venetian blinds b ...
For some time the building industry has been in need of a comprehensive reference that describes new and innovative technologies for utilizing daylight in buildings and assesses the performance of these systems. This information is of particular benefit to ...
