International Maritime Organization (IMO) proposed the Energy Efficiency Operation Indicator (EEOI) in 2005 and the Energy Efficiency Design Index (EEDI) in 2008 so as to address emission concern and regulation. Likewise, Ship Energy Efficiency Management Plan (SEEMP) and Greenhouse Gas (GHG) monitoring and management are also becoming an issue lately. This paper introduces the energy efficiency design index (operation indicator) monitoring system (EDiMS) software can continuously monitor $CO_2$, $NO_x$, $SO_x$, and PM values emitted from ship. The accurate inventory of ships GHG can be obtained from base of emission result during the engine shop test trial and the actual monitoring of shaft power and ship speed. In addition, the ability to store all exhaust emission and engine operation data can be applied as the useful tool of the inventory work of air pollution and ship energy management plan for the mitigation or reduction of ship emissions.

[Purpose] Recently, skyscrapers have sharply increased throughout the world, including South Korea. Although a skyscraper has its own merit such as the landmark of a city, it also has various problems like massive energy consumption. This study is aimed to establish the concept of environment-friendly skyscraper and propose a plan to realize skyscraper after analyzing the architectural, facility and environmental friendly elements of skyscrapers. [Method] This study lists up skyscrapers over 40 floors and 200 meters high. Upon 10 constructed buildings, it analyzes their basic plans and the green building technologies applied to them and suggests effective and environment-friendly architectural plan. [Result] This study examined the distinctions of the layout, shape, facade, and floor plan plane of 10 skyscrapers and found out specific techniques to be used for the use plan of natural energy, plan for saving resources and reducing wastes and a plan for environmental architecture and system.

The purpose of this study is to develope energy eco-audit evaluation scheme for the sustainable energy management at schools in accordance with education for sustainable development. Energy eco-audit evaluation scheme was developed through critical review of preexisting evaluation methods, consensus searching for the process from field. The results of this study are as follows. The school energy eco-audit evaluation scheme has three criteria: data collection, energy program, and environmental review. First, criteria of data collection includes general affairs, school building construction, and energy use. Second, criteria of energy program stresses school administration system such as the democratic decision-making process and structures. Third, criteria of environmental review includes reporting process and preparing teaching/learning materials for sustainable energy management. In conclusion, school energy eco-audit evaluation scheme could find a new way to achieve extended effect for sustainable energy management in school. It also could continue to seek opportunities to raise their awareness of energy issue and environment. School committee and whole school are involved to continue to implement present action plan and prepare updated plan in order to reduce environmental impact in school. By doing so, it would be possible to play important role in both school administration and education for sustainable development.

국내의 건물부문 에너지 소비량은 전체 소비량의 약 25%를 차지하고 있으며, 생활수준의 향상, 세대수의 증가 등에 기인하여 선진국 수준으로 지속적인 증가추세를 보일 것으로 전문가들은 예측하고 있다. 한편 정부는 2009년부터 녹색뉴딜사업의 일환으로 국토 에너지 수자원 건물 등의 각종 기본정보를 체계적으로 일원화시키고 통합 DB를 구축하는 녹색국가 정보인프라 사업을 추진 중에 있다. 특히 건물과 관련해서는 에너지 절약과 온실가스 저감 대책 마련에 효율적으로 대응하기 위한 수단으로, 건물단위의 에너지 소비량 관리를 기본 골자로 하는 건물 에너지 통합관리시스템 구축을 강구중에 있다. 본 연구에서는 국가 건물에너지 통합관리시스템 구축(이하, 통합관리시스템)에 요구되는 추진계획 및 로드 맵 작성을 목적으로, 기존 에너지 소비량 관련 자료 조사 및 전문가 면담 등의 분석을 통하여 통합관리시스템의 목표와 계획 수립에 따른 단계별 전략과제와 핵심과제를 도출하고자 한다. 나아가, 건물부문의 에너지 및 온실가스 통계 마련과 관리를 위한 통합관리센터의 구축과 운영방안 수립에 활용할 수 있는 방안을 제시하여 향후 녹색뉴딜 사업의 육성을 도모하고자 한다.

A nuclear energy has been one of the most important sources to securely supply electricity in South Korea. Its weight in the national electricity supply has kept increasing since the first nuclear reactor was built in 1978. The country relies on the nuclear approximately 31.4% in 2012 and it is expected to increase to 48.5% in 2024 based on the long-term electricity supply plan announced by the Korean government. However, Fukushima disaster due to 9.0 magnitude earthquake followed by the tsunami has raised deep concerns on the security of the nuclear power plants. The policy makers of the country are much interested in analyzing the cost structure of the power supply in the case that the nuclear is diminished from the current supply portion. This research uses a stochastic model that aims to evaluate the long-term power supply plan and provides an extensive cost analysis on the changes of the nuclear power supply. To evaluate a power supply plan, the research develops a few plausible energy mix scenarios by changing the installed capacities of energy sources from the long-term electricity supply plan. The analyses show that the nuclear is still the most attractive energy source since its fuel cost is very much stable compared to the other sources. Also the results demonstrate that a large amount of financial expenditure is additionally required every year if Koreans agree on the reduction of nuclear to increase national security against a nuclear disaster.

The effective energy management method will provide the significant advantage to the residential customers under real time pricing plan since it can reduce the electricity charge by controlling the energy consumption according to electricity rate. The earlier studies for load management mainly aim to minimize the electricity charges and peak power but put a less emphasis on the human comfort dwelling in the residence. The discomfort and displeasure from the energy management only focusing on reduction of electricity charge will make the residential customer reluctant to enroll the real time pricing plan. In this paper, therefore, we propose optimal load control strategy which aim to achieve not only minimizing the electricity charges but also maintaining human comfort by introducing "the human comfort coefficient." Using the human comfort coefficient, the energy management system can reflect the various human personality and control the loads within the range that the human comfort is maintained. Simulation results show that proposed load control strategy leads to significant reduction in the electricity charges and peak power in comparison with the conventional load management method.

IMO에서는 선박온실가스 규제를 위해 2013년부터 현존선의 선박에너지효율관리계획인 SEEMP (Ship Energy Efficiency Management Plan)의 시행을 강제화하고 있다. SEEMP에서 권고하는 에너지절감기술 가이드라인은 크게 하드웨어적인 장비의 탑재 및 개조 또는 소프트웨어적인 기술을 통한 연료유 절감효과로 구분된다. 신조선의 경우 하드웨어적인 기술구현이 용이하지만 현존선의 경우 운항상 제약으로 인해 소프트웨어적인 에너지 절감기술 구현이 적용되고 있다. IT기반의 선박에너지절감 시스템 성능평가를 위해 해상시험을 수행하였고, 시스템 적용 전후의 항차데이터를 이용하여 연료유 절감효과를 비교 분석 하였다. 또한, SEEMP에서 자발적인 사용을 권고하고 있는 선박 경제운항 지표 (EEOI, Ship Energy Efficiency Operation Indicator) 분석을 통한 성능평가 결과를 제시하였다.

Major accidents at nuclear power plants generate huge amounts of radioactive waste in a short period of time over a wide area outside the plant boundary. Therefore, extraordinary efforts are required for safe management of the waste. A well-established remediation plan including radioactive waste management that is prepared in advance will minimize the impact on the public and environment. In Korea, however, only limited plans exist to systematically manage this type of off-site radioactive waste generating event. In this study, we developed basic strategies for off-site radioactive waste management based on recommendations from the IAEA (International Atomic Energy Agency) and NCRP (National Council on Radiation Protection and Measurements), experiences from the Fukushima Daiichi accident in Japan, and a review of the national radioactive waste management system in Korea. These strategies included the assignment of roles and responsibilities, development of management methodologies, securement of storage capacities, preparation for the use of existing infrastructure, assurance of information transparency, and establishment of cooperative measures with international organizations.
