Analysis of Factors Affecting Energy Consumption in Student Dormitories

Against the backdrop of accelerated construction and green development concepts in university campuses, energy analysis of campus buildings can effectively provide a reference for improving the problem of excessive energy consumption, promoting the green and low-carbon transformation of campuses, and facilitating green and low-carbon development. Therefore, multi-dimensional research on building energy consumption is of great significance. This paper takes the student dormitory buildings of a certain university in Nanchang as a case study, using Revit software for simplified digital modeling and annual building energy simulation analysis. For dormitory buildings, the paper analyzes the effects of different factors on energy consumption from multiple dimensions, including building orientation, geographical location, and internal components, and proposes relevant reasons. The results show that different factors have significant differences in their impact on dormitory energy consumption. Rotating the building orientation 90 degrees clockwise increases cooling energy consumption by over 38%, and the best energy consumption performance observed when the wall thickness is 300mm. Furthermore, the total energy consumption and heating/cooling demand structures differ significantly among Nanchang, Beijing, and Hainan due to climatic differences. The research findings provide ideas and methodologies for university building design and contribute to China's "dual-carbon" goals.
