With the rapid growth of the campus building area, energy consumption of campus buildings has taken up a large portion in social energy consumption. To facilitate the construction management of economical campuses, we calculated and systematically researched of campus building energy consumption benchmarks using the theoretical methodology of building energy consumption baselines. We collected a great volume of energy consumption data, and used the SPSS statistical software to research on classification of campus construction. We proposed a method of classifying public teaching buildings based on their functions and air conditioning systems. Then, we calculated the energy consumption baseline of campus buildings using the quartile method. Finally, we obtained three kinds of baselines about low, average and high level energy consumption, respectively, and also put forward a correction method for these building energy consumption baselines.
