Analysis of school building energy consumption in Tianjin, China

Abstract

In order to investigate the characteristics of school building energy consumption, energy consumption of 17 schools in Tianjin have been counted and discussed. Based on the statistics, the results indicate that the average comprehensive energy consumption of school per unit area is 121.81 kWh/(m2 a), the average energy consumption per person is 36 kWh/(p a) and the average electricity consumption is 36.07 kWh/(m2 a) in 2007. It is found that the energy consumption per unit construction area is lower than the average energy consumption of public buildings, which is 257.61 kWh/(m2 a) in 2015.The main reason is that the quality of the thermal environment is poor and the running time of school is short. However, the school’s total energy consumption is large and we should pay more attention to it. At the same time, we point out the problems of the school energy consumption in Tianjin based on the statistics and proposed energy-saving reforms.
