Energy Consumption and Management in Public Buildings in China: An Investigation of Chongqing

摘要

Around 30% of the national energy consumption in China can be attributed to buildings, of which one-fifth is consumed within public buildings. In recent time, public buildings have been reckoned as the dominant objects for conducting energy efficient management. In order to obtain valuable information for the assessment of energy consumption status, an investigation was conducted in Chongqing-the youngest, largest and most dynamic municipal in China. A number of public buildings, including 28 governmental office buildings, 15 emporiums and 5 hotels, were selected for the investigation from the aspect of energy cost. Based on the collected data of electricity, water and gas, the characteristics of the energy consumption in each type of the public buildings are discussed, and the energy management in each type of public buildings is compared.
