The building basic information, form of cold and heat sources, and energy consumption of 40 public buildings in Tianjin, China have been collected and analyzed. The total construction area is 3846155.18m2. In 2014, the total comprehensive energy consumption is 59343.23tce, the total power consumption is 15673.69×104kWh. The average comprehensive energy consumption is 15.43kgce/(m2.a), the average power consumption is 40.75kWh/(m2.a). The function of building, building envelope and illuminating system has obvious effect on building energy consumption which is significant for energy saving reconstruction of existing buildings. The energy consumption of hospital building is much higher than that of government office building and school building.
