This study measured the amount of electricity consumed by the vending machines installed on campus and aim to come up with measures to address excessive consumption of electricity. We chose 10 universities located in the city of Seoul and Gyeonggi province and measured electricity consumption of 10 vending machines installed in each university. We then calculated annual electricity consumption of the machines based on previously calculated electricity consumption of 100 samples. According to the result of the calculation, it is estimated that the machines studied on consume 700 KWh a year. This amount could translate into approximately 3,000 tons of annual carbon emissions and 640 million KRW in annual electricity bills. It was also found that there is a significant difference between ordinary vending machines and machines certified for being eco-friendly and energy efficient, in terms of electric power consumption. It is expected that, if the ordinary machines are replaced with the eco-friendly and high-efficient machines, 640 KWh of electricity, 300 kg of carbon, and 61,640 KRW in electricity bills would be saved, which means 28% saving in energy, emissions and bills. In conclusion, we determined that, as one of the ways to reduce electric power consumption and carbon emissions, old vending machines on campus could be replaced with eco-friendly and high-efficient machines.

This paper proposes autonomous speed control strategy for an Electric Vehicle on urban road. SNU campus road is used to reperesent urban road situation. Motor efficiency of driving on campus circulation road can be improved by controlling velocity properly. Given information of campus road, especially slope of road, acceleration is selected from candidate, considering consumed power, human factor and driving time. To apply urban situation, preceding vehicle is also considered. With preceding vehicle, acceleration is defined according to clearance and relative velocity. Acceleration is bounded in normal range. Proposed acceleration control method is activated with proper velocity range for campus circulation road. With acceleration control, motor efficiency becomes better than driving with constant vehicle. To evaluate the performance of proposed acceleration controller, simulation study is conducted via MATLAB.

In the 21st century numerous universities continue to have an interest in building a more sustainable campus. The concept related to sustainable development and sustainability is applied to new master plan of university or university building planning. The field of sustainable development can be conceptually broken into three constituent parts: environmental sustainability, economic sustainability and social sustainability. The realization of sustainable development will become when considered eco-friendly life of users, not only environmentally friendly technologies. This study aims to research the method of sustainable access to university building planning in Europe and Canada. First, certification and standards will focused on acquisition Green Building Certification. Then we look at trends of sustainability based on users and community through the system of prior consultation between university and users. For the desirable development of the sustainable campus, the sustainable planning of campus should be investigated with campus community, members and local residents considering the generation, the preservation, the maintenance of existing building.

With the increasing demand in the production of concrete, there is a need for adopting a feasible, economical and sustainable technique to fulfill practical requirements. Self-Compacting Concrete (SCC) is one such technique which addresses the concrete industry in providing eco-friendly and cost effective concrete. The objective of the present study is to develop a mix design for SCC with Crushed Rock Fines (CRF) as fine aggregate based on the plastic viscosity of the mix and validate the same for its fresh and hardened properties. Effect of plastic viscosity on the fresh and hardened properties of SCC is also addressed in the present study. SCC mixes are made with binary and ternary blends of Fly Ash (FA) and Ground Granulated Blast Slag (GGBS) with varying percentages as a partial replacement to Ordinary Portland Cement (OPC). The proposed mix design is validated successfully with the experimental investigations. The results obtained, indicated that the fresh properties are best achieved for SCC mix with ternary blend followed by binary blend with GGBS, Fly Ash and mix with pure OPC. It is also observed that the replacement of sand with 100% CRF resulted in a workable and cohesive mix.

As the environmental industry grew bigger and bigger, the corcern about environmental condition increased and the demand of environmental expert tended to be much more increased. A lot of universities therefore established environment-related departments on campuses and ended up with producing numerous students every single year. However, some problems such as followings were in this study. First, the industry cannot adopt all the students directly from universities due to their low capabilities in environment affairs. Second, the universities yield much more students than the industry can actually adopt. In order to yield the appropriate students meeting the expectation of the industry, it is necessary to permit no more new department established on campus and to adopt new environmental field such as environmental management, eco-auditing and also 3+1 lecture system focused on real affairs.
