Energy efficiency measures on Beijing 's college and university campuses will greatly reduce emissions and save energy in the city , the municipality 's education authority said .
As about 100 colleges and universities take up energy conservation measures related to the heat-supply system , it is believed the city will save about 50 million cubic meters of gas during the winter .
"Many colleges are adjusting their heating system in accordance with the outdoor temperature ,wind power and sun illumination , so as to reduce gas consumption ," said Li Huayong , deputy director of the energy conservation and emission reduction office under the Beijing Municipal Commission of Education .
In addition , many colleges and universities also are lowering the indoor temperature in the teaching building at night and during winter vacation , when fewer people are around , to save energy , he said .
According to China Agricultural University , the campus saves about 15 percent of energy use a year thanks to the boiler improvements on campuses .
"The network of pipes , which is controlled by central computer and can achieve a high-level district heating system , will prevent unnecessary energy consumption ," said Zhang Jingyu ,deputy director of the energy management center of the campus .
"This alone can save some 400,000 cubic meters of natural gas every year , which is 900,000 yuan ($143,800)."
The city is also carrying out water and power-saving measures as well to further reduce energy consumption , according to Nan Bin , director of the heating supply office of the Beijing Municipal Commission of City Administration and Environment .
Campuses are among the major energy consumers , together with shopping malls , office buildings and hotels , and energy conservation enforcement at colleges and universities will greatly reduce emissions in the city , he said .
