Analysis of Key Factors of Energy Consumption in University Teaching Buildings

In response to the goals of improving energy efficiency and achieving dual carbon, this study focuses on high-energy-consuming university teaching buildings, aiming to identify the key factors affecting their energy consumption and to provide a reference for related energy conservation work. The study selected four building cases with the same basic parameters and set up the control and experimental groups using the control variable method. The effects of geographical location, building type, and enclosure structure were discussed, respectively. The annual energy consumption was simulated and analyzed by professional software. The results show that the three factors have a significant impact on the energy consumption of the teaching building, and the role of the envelope is the most prominent, followed by the geographical location, which has a relatively small impact on the building type; At the same time, heating and refrigeration related energy consumption accounts for the highest proportion of the total energy consumption, which is the core link of energy consumption regulation by various factors. This study clarifies the roles of various factors in the energy consumption of teaching buildings, provides clear guidance for targeted implementation of energy-saving measures in the design, transformation, and operational management of university teaching buildings, and helps reduce energy consumption in these buildings.
