In this rapidly changing environment in 21st century, countries around the world interact closely with one another to respond to changes. Universities are not an exception in this trend. As the home of knowledge, universities are exercising more influence on the state and local communities than before as well as being asked to come up with new requirements to respond to such changes. The study aims to derive new concept of sustainable green campus planning based on theories and researches of university facilities planning and campus planning to respond to university's needs for sustainable growth, enhanced competitiveness and globalization. Through the case study of green campuses, this study analyzes the types and characteristics of green campuses, and redefines the elements of its architectural planning. Design elements drawn by centered architectural design are classified, and this research presents the new concept of campus planning by using this classified elements. This is a new concept of campus planning application as a prototype, and in the further study, a variety of examples and detailed sector research is required.

Recently, as the environment issue has been stand out, people's interests in energy consumption of the building have been increased as well. Especially, university has been classified as the one of the main causes of excessive energy consumption. Therefore, domestic and foreign universities are trying to build a green campus in an attempt for sustainable development. Since early 2000s, foreign universities have been aware that one of the main causes of global warming is an excessive consumption of energy in universities. Accordingly, they adopted various energy management programs for the conservation. Ultimately, enforcing energy conservation and using alternative energy resulted in lower expense and it was a great help for the universities. On the other hand, excessive consumption of energy in domestic universities has been considered as serious, which led them to become the second main energy consumers in 2010. However, it seems people do not truly recognize the impotance of energy management, therefore, relatively little attention has been paid to this matter. Based on Leadership in Energy & Environmental Design(LEED) rating systems for on-campus building operation and maintenance, this research suggests the evaluation standard to effectively analyze the energy management activity with the best practices conducted in foreign universities and to solve the problem of campus facilities management in domestic universities. The result shows that domestic universities do not have a designated task force for effective energy management and the lack of energy professionals hinders for the long term development. Therefore, domestic universities should recognize the seriousness of the excessive energy consumption and develop low carbon green campus through proactive management practices since this is very essential for domestic universities to get more competitive in this global era.

Recently severity of ecological adaptation and climatic change due to global warming grows larger. According to the fourth report of IPCC in 2007, emission quantity of the earth greenhouse gas(GHGs) generated by activity of mankind increased with 80% since 1970. And it is forecasted that worldwide greenhouse gas will be increased with 25~90%(corresponding to $CO_2$) between 2000 and 2030. This increment of greenhouse gas($CO_2$) is expected to raise average temperature of the earth with the maximum $6.4^{\circ}C$, and sea surface with 59cm in 2090. Like this, destruction of environment by greenhouse gas is regarded as universal problem threatening the existence, not only the problem of one nation. Consequently, systematic correspondence to the global warming at the aspect of energy consumption is also needed in Korea. From the analysis result of 'Statistics of Energy Consumption' published by Green Korea in 2007, energy consumption increment of domestic universities was higher as many as 3.7 times than 22.5% of the whole energy consumption increment in our country. This says to be the direct example which shows that universities are huge sources of greenhouse gas emission. New constructing and enlarging buildings of each universities within campus are the most major reason for such a large increment of energy consumption in universities. The opinion that the possibility of causing energy waste and efficiency reduction is raised by increased buildings of universities has been propounded. That is, universities should make concrete goal and the plan for reducing emission of green house gas against climatic change, and should practice. Accordingly, there is the meaning that 2 aspects of environment-friendly design characteristics, that is application of energy utilizing technology, material usage of energy efficiency-side and environment-side, and introduction of natural element in the environmental aspect, were analyzed for facilities of university campus designed in environment-friendly point of view from initial stage of plan, and direction of environment-friendly design of university facilities in the future was groped in order to grasp environment-friendly design tendency of internal and external University facilities based on this analysis of this paper.

This study examined the composition and spatial characteristics of the Illinois Institute of Technology (1939-1959) campus by Mies van der Rohe. Studies of the Mies' architecture has been focused mostly on "universal space", structural rationality for a single building. Therefore, it is interesting to study an IIT campus through which Mies composed public space dealing with several buildings together. To determine the relationships with his previous works and the design intentions for IIT campus, this paper studied his preliminary sketches, perspective drawings etc.. By doing so, the paper presents the following conclusions. First, Mies composed the IIT campus with simple linear buildings as walls to create the "flowing space" through the campus. Secondly, the IIT campus could become the "neutral frame" integrating the campus with urban space. Third, Mies also created an open, continuous public space in the center of the campus that allows protective, quiet seclusion for the students.

Green campus means the environmentally-conscious universities that are trying to increase campus sustainability by reducing carbon emissions, expanding eco-friendly activities. This study was carried out to compare the recognition level on green campus between Korea and Japan universities. For investigating the recognition level of students and faculties on green campus, the questionnaire surveys were conducted by personal interviews in Korea and Japan, separately. The 40% and 68% respondents in Korean A and B universities, respectively, pointed out the energy issue as one of the serious environmental problems while the corresponding ratio among Japanese respondents was 44% and 34%. The participation intention for green campus movement in Japanese universities was higher than Korean universities. The 70% or 52% of Korean students in A and B universities, respectively, replied that they did not participate the green campus movement. It is needed to strengthen the educational program to achieve the sustainability of campus in Korea.

Since the Paris climate agreement, reducing greenhouse gases has been the most important global issue. In particular, it is necessary to reduce fossil fuels in the mobility sector, which accounts for a significant portion of total greenhouse gas emissions. In this paper, we investigated the economic feasibility of green mobility energy supply chains, which supply hydrogen as fuel to hydrogen vehicles based on electricity from renewable energy sources. The design and operation costs were analyzed by evaluating nine scenarios representing various combinatorial possibilities such as renewable energy generation, hydrogen production through water electrolytes, hydrogen storage and hydrogen refueling stations. Simulation calculations were made using Homer Pro, widely used commercial software in the field. The experience gained in this study could be further utilized to construct actual hydrogen energy systems.

It has been stand high in estimation to converse from Carbon dioxide to Dimethyl Ether in new alternative fuel energy division in 21C, especially Using of DME in point of view of transportation fuel has been discussed of a new clean energy which is very lower of exhaust gas than gasoline and diesel energy. In this paper it is used ZSM-5 and I developed new catalyst by addition of cerium to control acidity. The new catalyst was proved high conversion rate, when it was conversed from methanol to DME, there wasn't any additional material except DME and water, and I overlooked reaction temperature, reaction time, amount of catalyst, amount of added cerium, effect of water content in methanol, reaction temperature by making change of reaction time. I have conclude that conversion rate to DME was increased as increased of catalyst amounts. The best catalyst condition of without additional product was treated poisoning from ZSM-5 to 5% cerium and new catalyst was not effected in purity of fuel methanol.
