| Abstract: | As a huge energy consumer, China's energy-saving situation is urgent, while the building plays an important role in the whole country's energy conservation. As residential building accounts for a considerable capacity of building construction, the energy consumption of residential building has great guiding significance and research potential. Therefore, studying the influence of construction parameters and HAVC settings on energy consumption, and research the measures of optimizing residential building design, has already become a meaningful topic. In this dissertation, a typical residential building that has 6 floors and a total of 36 households is taken as a study case. Three cities in China are selected as research locations: Beijing, Shanghai, Guangzhou that located in the cold zone, hot summer and cold winter zone, hot summer, and warm winter zone, respectively. The research method of this dissertation is software simulation. This study explores the impact of construction parameters like wall configuration, window material, and window-to-wall ratio, as well as HAVC settings such as indoor air temperature set-point. This dissertation is trying to seek a more optimal design of residential buildings in different climate zone, therefore reducing cooling energy consumption. This dissertation collects and analyzes the previous study results, summarizes some factors that influence the cooling energy consumption of the residential building. Based on this, the construction parameters and air conditioning settings that affect the cooling energy consumption of residential buildings are chosen as the object. Firstly, the background and significance of the research object are introduced, as well as reviews and summarizes the research results of previous literature. Secondly, this dissertation explores the impact of construction and HAVC setting on cooling energy consumption, including four aspects such as indoor air temperature set-point, insulation thickness of the exterior wall, window-to-wall ratio, and window material. Finally, this study has researched the effect degree of these influence factors on cooling energy consumption, therefore summarizing a more optimal design to realize the aim of energy-saving in different climate zones. In this dissertation, the effects of these parameters on cooling energy consumption were researched for three cities in different climate zones in China, namely, Beijing, Shanghai, Guangzhou. The simulation and cooling energy consumption calculations were accomplished by DeST, which was developed by Tsinghua University. With this software, annual cooling energy consumption with different building parameters can be obtained. This dissertation makes a comprehensive assessment and comparison of research results in the following chapters. The result indicates that these parameters influenced cooling energy consumption with various degrees, the importance order is indoor air temperature set-point>window-towall ratio>window material>insulation thickness. This research also includes comparison in three cities, the change degree of cooling energy consumption in Guangzhou is always highest, while Beijing has the highest energy saving rate. |
