Caractérisation, analyse et modélisation des échanges énergétiques entre un mur végétalisé intensif et son environnement / Characterization, analysis and modelization of energy exchanges between a green wall and its environmentKenaï, Mohamed Amine 20 September 2016 (has links)
Ce travail de thèse vise à comprendre et analyser les échanges thermiques qui ont lieu entre un bâtiment et son environnement en présence de parois végétalisées « intensives ». Nous présentons dans ce manuscrit, une démarche numérique et expérimentale sur l’évaluation de l’incidence thermique de ces Murs Végétalisés (MV). Une plateforme constituée de trois prototypes identiques (3 mini-laboratoires thermiques) sous conditions climatiques réelles a été conçue et instrumentée. Dans un premier temps, deux écrans permettant une variation rapide et graduelle des taux de couvertures de 10 à 100% ont été ajoutés devant les prototypes. Ainsi, plusieurs séries de mesures ont été effectuées et des réductions significatives au niveau des températures et des flux de chaleur ont été enregistrées et interprétées. Cette démarche expérimentale avait pour premier objectif de mettre en oeuvre une occultation artificielle et donc maîtrisée. Un premier modèle a été développé sur la base de l’écriture des équations de bilan des échanges thermiques entre la paroi à occultation variable et son environnement climatique. Ce modèle confronté aux résultats fournis par l’expérimentation apermis de valider les approches théoriques au niveau des transferts radiatifs et convectifs. Dans un deuxième temps, le premier modèle qui a été développé dans ce travail a été adapté au cas d’une occultation « réelle » par de la végétation (lierre ou vigne vierge) puis validé expérimentalement. Il a été finalement implémenté dans un code de simulation thermique dynamique de bâtiment (TRNSYS), et ainsi l’incidence thermique des murs végétalisés simples (intensifs) a pu être évaluée à l’échelle réelle d’un bâtiment. Les résultats de simulations pour un climat tempéré montrent que la présence des plantes à feuilles persistantes a un impact négatif sur la demande énergétique hivernale. A l’inverse, en période estivale, les résultats montrent que les murs végétalisés ont un intérêt au niveau de la limitation des surchauffes. Leur présence réduit alors notablement la consommation énergétique nécessaire pour « climatiser » le bâtiment et améliore ainsi le confort thermique intérieur. / This PhD thesis aims to understand and analyse the heat exchanges that occur between a building and its environment in the presence of intensive vegetated walls. In this manuscript, a numerical and experimental approach to evaluate the thermal impact of green walls is presented. A platform composed of three identical prototypes (3 thermal mini-laboratories) under real weather conditions has been designed and instrumented. As a first step, two screens permitting a rapid and gradual variation of coverage rate from 10 to 100% were added to the prototypes. Thus, several series of measurements were performed and significant reductions in temperature and heat flow were recorded and interpreted. The primary objective of this experimental approach was to implement an artificial shading and thus controlled. A first model was developed based on the writing of heat exchanges energy balance equations between the wall with variable coverage rate and its climatic environment. This model confronted to the experimental results allowed the validation of the theoreticalapproaches at the level of radiative and convective heat transfer. Secondly, the first model that was developed in this work has been adapted to the case of a "real" occultation by vegetation (Ivy or Virginia creeper) then validated experimentally.It was finally implemented in a dynamic thermal simulation code (TRNSYS), and thus the thermal impact of green walls were evaluated at the real scale of a building. Simulation results in a temperate climate show that the presence of evergreen plants has a negative impact on winter energy demand. Conversely, in summer, the results show that green walls have an interest in limiting overheating. Their presence significantly reduces energy consumption needed to cool the building and improves the indoor thermal comfort.

Uhlíková stopa ve stavebnictví a její teoretická hodnota / The carbon footprint of the building industry and its theoretical valueHalama, Miroslav January 2018 (has links)
Presented theses dealing with the complex influence of human activity on the environment. Particularly provides the calculation of carbon footprint volume consumed during manufacturing of raw materials used for a normal and a low-energy house. The calculation of the energy performance certificate for both variants is also included. To evaluate of economical demanding investment to both mentioned houses including carbon dioxide disposal, the theoretical calculation of the price of carbon footprint equivalent has to be determined. The aim of this study is an investigation of carbon footprint in construction industry focusing on the production of carbon dioxide during the realization of a normal and low-energy house.

Simulace energetické náročnosti a reálné užívání budov / SIMULATION OF ENERGY PERFORMANCE AND REAL OPERATION OF BUILDINGSŠteffek, Libor January 2020 (has links)
This dissertation thesis primarily focuses on the experimental measurement of energy consumption of a given energy-passive family house as well as theoretical research in the field of energy calculations using computer simulations. The results of quasi-stationary and dynamic simulations, with varying computational and real-time climate data, are compared with experimental measurements. Using the dynamic calculation model, which was validated by actually measured data, the relationship between architectural design and the energy performance of the building was analyzed. The influence of selected different operating modes for heat consumption on heating, cooling, ventilation, and interior overheating is observed. The result of the mutual interaction of several input parameters of variant solutions provides the basis for optimization of the whole design.
