Pei, Long. "Evaluation of environmental impacts of buildings in China." Electronic Thesis or Diss., Université Paris sciences et lettres, 2020. http://www.theses.fr/2020UPSLM068.
Full textThe urbanisation process in China brings a high pressure on the environment. The highest potential to reduce these impacts corresponds to decisions made during the building’s design phase, which can be supported by numerical simulation. This thesis is dedicated to the study of three boundary conditions related to the energy and environmental performance evaluation of buildings in China: - The ground: a ground coupled heat pump model is proposed integrating a fast calculation ground heat exchanger model for a large-scale boreholes field. This model can be used to improve the energy performance of the system in the design and operation phases. - The microclimate: a site-specific weather file generation method which can provide local hourly air temperature is proposed, accounting for the urban heat island effect. The effects of the microclimate on the building’s energy performance are quantitatively investigated. - The background system for life cycle assessment: the effects of the spatial and temporal variation of the electricity production mix in China on the environmental impacts are investigated. The environmental database is adapted to the Chinese national and local context. The results show that the environmental impacts of buildings could be more reasonably evaluated by considering these three boundary conditions

Full textThis thesis deals with the thermal and energy analysis of a geothermal ventilated fonudation. Similarly to earth-to-air heat exchangers (EAHE) this foundation enables, according to the season, to preheat or to cool down the air for the hygienic air change. Considering the energy consumption constraints and the buildings users thermal comfort desire, these systems appears to be relevant. The principle of this foundation is simple: to force the air to circulate in a hollowed beam buried into the ground (1 to 3m depth) so that it takes advantage - via convection - to the thermal inertia of the ground. The difference lays on the fact that the channel is not a plastic or aluminium pipe but it a part of the building structure, namely the reinforced concrete foundation. This induces a significant space gain, usually devoted to the pipe burying. From a thermal point of view, the foundation exchanges heat with both the soil beneath the building, and with the soil exposed to the weather thermal loads. Furthermore, the depth - imposed by structural and economical purposees - is lower than that of traditional EAHE. In addition to the fact that concrete is a porous material, the humidity content may strongly influence the thermal performance of the foundation. The current work thus proposes to study the complex thermal behaviour of this foundation in two ways. The first is experimental: an retirement home equipped with two foundation has been intensively instrumented and data recorded over more than one year. The other is numerical: two models validated against the experimental data have been developed. The first is intended to be a designing tool, the second a tool to allow a fine comprehension of the physical phenomenon and take into account coupled heat and moisture transfers
