| Traditional farm buildings require a lot of energy to build and operate,thus China is focusing on finding innovative farm building models to save energy and cut down on consumption.Combining near-zero energy consumption technology with light steel structure farmhouse and creating near-zero energy consumption oriented light steel assembly farmhouse can significantly reduce China’s energy use for buildings,enhance China’s energy infrastructure,and maintain national energy security.It can also advance sustainable societal development and realize economic recycling development,which is crucial for the creation of new societal structures.In this thesis,we looked at the general situation of rural houses in Xuzhou,the envelope structure,and energy consumption,looked into the current issues with rural houses in Xuzhou,and finally proposed a solution appropriate for rural houses in Xuzhou,on the basis of which we finally showed the viability and economy of the technology in design practice.To solve the aforementioned issues,a study on the nearzero energy focused design of a light steel constructed farmhouse in Xuzhou is conducted in this thesis.The following are the primary research findings:Firstly,in the preliminary survey,it was determined that the construction techniques and energy-saving technologies used in earlier farmhouses were comparatively inefficient,which contributed to their high energy consumption.Next,the research on households,houses,and energy consumption in Xuzhou rural areas was used to analyze the main issues in the current farmhouse construction process.Secondly,to understand the prospective needs of the villagers and connect the theoretical analysis of rural housing in Xuzhou with the fundamental tendencies in spatial development,a factual survey of housing in rural regions of Xuzhou City was carried out.Ultimately,a collection of representative typical residential floor designs appropriate for Xuzhou’s rural regions is created based on the needs of the villagers.Next,optimized light steel assembled farm buildings are acquired in order to provide fundamental techniques and information for their ideal design.Thirdly,this thesis focuses on the impact of energy consumption during the cooling and heating seasons as well as the overall energy consumption of rural homes.To avoid the formation of thermal bridges and enhance the airtightness of the outer envelope,the problems with thermal bridges and the outer envelope of the light steel constructed farmhouse should first be addressed;the thermal climate of the Xuzhou farmhouse was examined using Climate Consultant software,and design parameters were chosen and quantified using Design Builder.Then,using SPSS software,an orthogonal test with an extreme difference analysis was performed to determine the weights of energy consumption during the cooling and heating seasons as well as the total amount consumed.This allowed researchers to identify the best solution for the cooling and heating seasons as well as the entire year,and it also allowed researchers to combine solar energy utilization technology to effectively use the available energy for the Xuzhou area’s near-zero energy goals.This will serve as a benchmark for the light steel-assembled farmhouse in Xuzhou’s near-zero energy consumption criteria.Lastly,a plot in Xuzhou City,Jiangsu Province is used as a practical case to implement the design scheme of the Xuzhou area light steel constructed near-zero energy home,along with the simulation technology,demonstrating the viability of the strategy system and enhancing its practicality. |
