| Popis: | 98 In recent years, governments and schools in Taiwan have cooperated to reduce electricity usage in order to fulfill the national “Energy-saving and Carbon-reducing measures”.The universities in Taiwan, which are the main users of electricity for educational purpose, are demanded to develop and achieve carbon neutral. National Pingtung University of Science and Technology (NPUST) was selected in this study as an example. The research collected activity intensity in the campus of NPUST, and defined the green house gas (GHG) emissions category. According to greenhouse gas quantitative methods, the greenhouse gas emissions were calculated and then a detailed list of greenhouse gas produced from the NPUST campus activity was developed. Finally, the solutions to reduce the NPUST greenhouse gas emissions and carbon offset were proposed. This study found that the power consumption on campus buildings accounts for more than 90% of campus GHG emission. After deducting carbon sequestration of the forest, the total emission in 2008 should be deducted 13111.17 tons of CO2e (or 20615.04 degrees of electricity). Thus, an equivilent amount of greenhouse gas needs to be offset in order to neutralize carbon in the campus. The calculated greenhouse gas indexes for NPUST campus are: 0.001160717 ton CO2e/m2 for school areas carbon intensity, 0.044359 ton CO2e/m2 for building carbon intensity, 1.125 ton CO2e/capita for per capita (including faculty and students), and 103.66 kWh/m2/yr for energy use intensity (EUI). Even though the EUI value of NPUST is below the government threshold value, the result of this research suggests that the school develops energy saving plans in order to cooperate the request of MOU (Minister of Education), which demands a negative electric growth each year. Due to the hot weather, there are numerous air conditioners on campus. Considering its high power consuming, an intelligent air conditioner regulation system is suggested. The use of such a system is predicted to reduce the highest percentage of carbon emission. Furthermore, if the electric supply of campus power can be replaced by green energy instead of thermal coal, the target of Carbon Neutral can be achieved. There are two electrical systems applicable to NPUST: combined heat and power and wind energy and photovoltaic system. |
