Urbanization is one of the major events in the 21st century has caused rapid growth in the global construction area, which resulted in high consumption of building resources and long term environmental impacts. Analyzing the resource consumption of public buildings and identifying the key factors that affect the consumption of building resources is therefore important for the development of targeted policies. In this paper, we analyzed each branch of the People’s Bank of China based on energy, water, and land resource consumption as well as the structure of energy consumption. Based on resource-consumption indicators, we divided 31provincial administrative into four resources consumption levels; of these, 65% were in the middle or low resource consumption levels. Medium-sized institutions had the highest energy consumption level and more balanced energy consumption structure. Energy consumption per capita, water consumption, and utilization rate of small-sized institutions were low. To reduce resource consumption by public institutions, construction of large-sized institutions should be limited.
