Analysis of Energy Consumption Structure of a Science and Engineering University Campus in Southern China

Abstract

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 ����������������������������������������������������������������������������������������������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 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. . Keywords: A Science and Engineering University Campus in Southern ChinaIn former research in Japan, various works have been reported on the verification of energy conservation through investigations of the energy consumed in the entire campus. Watanabe 2) carried out research to clarify the actual conditions of energy consumption of a school building in Tohoku area.Lee 3) proposed an optimal energy consumption system and how to make a comfortable educational environment and evaluation of perimeter annual load by energy conservation techniques. On the other hand, the introduction of the Combined Gas-steam System (CGS) on campus was also being discussed considering the issues of fossil fuel resource depletion and global warming. exists that is based on field studies of actual operating system, especially on detailed data analysis of the energy consumption structure and energy consumption unit [7][8][9] .In China, universities can be regarded as small cities due to their large size, numbers of students, and the various activities taking place in campuses.According to statistics by the Chinese Ministry of Education in 2010, the numbers of universities in China were 2,305, the total numbers of students were 24.26 million, and the floor area was over 656.11 million m 210) . There is great potential for energy conservation if it is expanded to all univers...

Methodology of Measurement and Calculation of Building Energy Management System in University Campus

“…While considering the different measurement of buildings with same usage, the energy consumption amount of the whole campus can be calculated and forecasted. The energy consumption amount of the whole campus for daily, monthly and yearly is illustrated in Eq.4-6 [10][11].…”

Economic Evaluation of Environment-Friendly Streetlights on a University Campus: Using a Field Survey in Korea

“…The Kyoto Protocol on Climate Change (the Kyoto Protocol), which has been in effect since 2005, enforces mandatory GHG emissions reduction on 38 developed countries 16) ; the Kyoto Protocol also has introduced the emissions trading system to encourage flexible implementation. Emissions trading is, put simply, a system that allows countries to buy and sell the right to emit GHG emissions.…”

Effect Evaluation of Introduced Building Energy Management System in University Campus

“…According to statistics by the Ministry of Education in 2009, the number of universities in China was 2166, the total number of students was 22.85million, and the floor area was over 600 million m 2 [1]. The potential to developing energy conservation have great opportunity if it can be expanded to all the university campuses in China.…”
