This paper presents in depth analysis of the actual energy consumption structure of a science and engineering university campus in southern China. It also clarifies for the first time the hourly energy consumption characteristics of such campus buildings in this area. Firstly, the measurement meters were installed on the power circuits of 11 different buildings in the campus to obtain hourly end-user energy consumption data from Sep.1
st 2009 to Aug.31
st 2010. Then examination of energy consumption unit according to the different buildings has been analyzed base on the measured data. Furthermore, the energy consumption of buildings with different usages has been evaluated; the analysis was performed for different days and different load periods. Finally, a detail of energy consumption unit was discussed and constructed based on it.
From the analysis, variation of daily energy consumption unit structure of different usage buildings and the whole campus is clearly indicated. The energy consumption of the research laboratory buildings accounted for 58% of the whole campus' energy consumption. The average daily energy consumption unit of the library was the highest. Among the proportion of the total energy consumption for the whole campus, the cooling consumption accounted for 52% with 72.18 MJ/(m
2•a), electricity consumption of lighting and electrical socket accounted for 23% with 32.01 MJ/(m
2•a). The maximum value of hourly average electricity consumption unit for the whole campus in each month was recorded at 12:00 Oct. 2009 with 24.08 kJ/(m
2•h) and the maximum value of hourly average cooling consumption unit was recorded at 16:00 Oct. 2009 with 71.14 kJ/(m
2•h) respectively. The energy consumption unit in different load period was listed to indicate which building and which period consumed more energy. In particular, this study we aim to find out peak energy unit of the different buildings, in order to make a proposal for energy conservation measures to reduce peak energy amount of the whole campus to the greatest possible extent.
