▲ The solar generation facilities fo the 2nd Engineering Building
On Oct. 17, UOS reported that UOS had accomplished a 15 percent reduction in energy consumption by installing energy-saving facilities for about nine months from the beginning of this year to September. The amount of electricity used was 12,925 megawatthour (Mwh), which is now compared to 15,210 Mwh used during the same period last year. This success was largely due to large solar generation facilities on the rooftops of nine buildings. They are the largest scale among universities in Korea and have a generating capacity of 353 kilowatt (kW). The facilities generate a total of 479 Mwh every year which is three percent of total energy use in UOS. This system can cut expenses by 380 million won annually and has as much of an effect on reducing carbon dioxide emissions as the oxygen produced by 220,000 pine trees.
In addition to this, high efficiency LED Lighting accounts for 92 percent of the whole campus lighting in UOS. Compared to general light, this can save 2,710 Mwh annually. And this ratio is already much higher than any other public institution?s goals. With these efforts, UOS could reduce amount of electricity used steadily and achieved three percent energy self-sufficiency. In future, UOS sets a goal to achieve six percent energy self-sufficient.
In fact, energy consumption at universities has emerged as a major issue recently. According to the Seoul Institute, energy consumption by the city was down 1.8 percent but universities in Seoul increased 32 percent during the period from 2007 to 2011.
That is why UOS is playing an active and leading role with the city of Seoul by creating a Green Campus. Making a Green Campus involves not only renovating or changing facilities but also encouraging the participation of the university community.
Ahn Jong-kyeong (Dept. of Public Administration, '11) said, “On first floor of the University Center, I saw a graph depicting energy consumption. However, except for this, I could not see any other facilities or understand how UOS pays attention to energy consumption. I think that posting a graph of energy consumption in every building is good thing for students.” Now it is our turn to show what we can do.
