Résumé
Methodologies developed for the analysis, improvement and optimization of energy systems must take into account not only energy use (exergy consumption) and financial resources expended (economics), but the scarcity both present and future of all resources used as well as any pollution and degradation of the environment which may occur. Along these lines, parallel works which take some or all of the above factors into account have recently been published by Frangopoulos (1991, 1992) and von Spakovsky (1991, 1992). What follows is Part II of a series of two papers. They represent an attempt to combine certain aspects of these works into a global methodology

Énergie primaire
Une source d’énergie primaire est une forme d’énergie disponible dans la nature avant toute transformation. Si elle n’est pas utilisable directement, elle doit être transformée en une source d’énergie secondaire pour être utilisable et transportable facilement. Dans l'industrie de l'énergie, on distingue la production d'énergie primaire, de son stockage et son transport sous la forme de vecteurs d'énergie et de la consommation d'énergie finale.
Energy system
An energy system is a system primarily designed to supply energy-services to end-users. The intent behind energy systems is to minimise energy losses to a negligible level, as well as to ensure the efficient use of energy. The IPCC Fifth Assessment Report defines an energy system as "all components related to the production, conversion, delivery, and use of energy". The first two definitions allow for demand-side measures, including daylighting, retrofitted building insulation, and passive solar building design, as well as socio-economic factors, such as aspects of energy demand management and remote work, while the third does not.
Transition énergétique
La transition énergétique désigne à la fois l'évolution passée de la répartition des énergies consommées sur la planète (bois, hydroélectricité, charbon, pétrole, gaz naturel, nucléaire, etc.) et, pour l'avenir, l'objectif politique et technique d'une modification structurelle profonde des modes de production et de consommation de l'énergie. C'est l'un des volets de la transition écologique.

Absolute energy levels of liquid water from many-body perturbation theory with effective vertex corrections
Alfredo Pasquarello, Aleksei Tal, Thomas Bischoff
We demonstrate the importance of addressing the F vertex and thus going beyond the GW approximation for achieving the energy levels of liquid water in manybody perturbation theory. In particular, we consider an effective vertex function in both the polariz ...

The presentation delves into the significance of the concept of the Environment in Architecture, examining whether the term could be construed as a constant or a variable. Supported by a series of examples from the Alpine context, it seeks to illuminate th ...
