摘要：

The energy supply in Japan faces challenges after the Great East Japan Earthquake. The electricity consumption and the energy consumption for cooling before and after this earthquake in a high-rise university with BEMS is investigated. Compared with the energy consumption in 2010, about 22% of the electricity consumption and 20% of the energy consumption for cooling is cut down in 2011. According to the hourly data for lighting, electric outlets, cooling systems, the load patterns for different energy consumption are studied. The results show that the load patterns before and after the earthquake are quite similar. Furthermore, the difference of energy consumption for cooling in similar climate conditionings in these two summers is pointed out, which illustrates the effectiveness of energy saving methods adopted. Compared with the contracted electricity demand, 15% of the peak electricity demand is cut down in the summer of 2011.
