Evaluation of environmental impacts of buildings in China

Abstract : The 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.
