university buildings energy consumption monitoring system energy use characteristic energy use behavior influencing factors
To better understand energy conservation in university buildings,this paper analyzes the energy consumption status and the influencing factors of energy use behavior in a typical science and engineering university in the hot-summer and cold-winter zone in China. Based on the database of the 2013-2016 yearly energy use collected from energy consumption monitoring system(ECMS),the current energy consumption data of both the whole university campus and its typical buildings are analyzed to explore the energy consumption characteristics of the different buildings with typical functions,such as teaching building,dormitory building,R&D building,etc. Besides,the energy consumption peak contribution factor is explored to analyze the building’s proportional contribution to campus-wide energy consumption peak,and the correlation analysis between seasonal factors and energy consumption is conducted accordingly. The energy consumption and monthly average temperature method is used to quantify the impact of student behavioral factors on energy consumption in one case study. The results indicate that the typical energy consumption level of the university campus buildings is 44.79 kW·h/m2,and the‘best practice’ value is 32.44 kW·h/m2. There are significant differences of the energy characteristics among different functional buildings,in which the chemical laboratory building contribute most to the campus peak both in the cooling and the heating season. The students’ energy use behavior in this case study has a greater impact on campus building energy use,accounting for more than 60%.
