The requirement of sustainability in the field of building industry pushes many countries to make green building assessment systems. Korea has also made a green building assessment system, named GBCS (Green Building Certification System) and started to implement the GBCS in 2002. During 10 years of operation, GBCC has been upgraded in the structure of the criteria. The types of buildings to assess have been expanded and there are seven building types for the assessment nowadays. However, the structure of the operation system needs to be considered. The main bodies for the assessment process are the governing body by the government (MLTM & MOT), eleven certification bodies (seven of them are recently nominated by the government) and a newly established operational body. For establishing objectivity of the certification result, we need a proper process such as QA(Quality Assurance) System during the certification process. This research investigates the operation processes of BREEAM(Building Research Establishment Environmental Assessment Method) and CSH(Code for sustainable Homes), and they are compared with the operation process of GBCC. The role of the operational body and the relationship among the governing body (the government), the operational body (KICT) and eleven certification body are investigated. Finally the operational process of GBCC with the adaptation of QA(Quality Assurance) is suggested.

현재까지 목포항의 효율성을 분석하고 우리 나라의 다른 주요 무역항만과 비교하여 항만의 개발 방향을 개선한 연구는 많지 않다. 본 논문에서는 Malmquist Productivity Index (MPI)와 함께 DEA (Data Envelopment Analysis) 모형을 사용하여 목포항을 중심으로 우리나라 주요 무역항만의 효율성과 생산성을 측정한다. 첫째, 항만의 기술적 또는 운영 규모에 따라 어떤 항만이 효율적이거나 비효율적인지, 그리고 몇 년 동안 어떤 항만이 생산성을 유치할 수 있는지 파악하고자 한다. 둘째,이 연구는 어떤 항만의 그룹이 효율성 점수가 높거나 낮은지 분류하는 데 Fuzzy C-means (FCM) 클러스터링 방법을 적용한 후 목포항의 개선 방안을 제시하고 자 한다. Until now, there have been few studies analyzing the efficiency of the Port of Mokpo and comparing it with other seaports in the country to identify the future direction of development for the port. In this paper, we use the data envelopment analysis (DEA) model in combination with the Malmquist Productivity Index (MPI) to measure the efficiency and productivity of major ports in Korea, focusing on the Port of Mokpo. First, the study identifies which ports are efficient or inefficient based on technical or operational scale. Second, by using the MPI to overcome the shortfalls of the DEA model, the study can compare a port’s performance across the years and evaluate the productivity of a port during the research period. Moreover, this study also applies fuzzy C-means (FCM) clustering to classify port groups based on the size of their infrastructure and their efficiency scores. Finally, it is possible to find ways to enhance the efficiency and future direction of development of the Port of Mokpo.

Ice Rink is energy intensive building type. Concern of energy saving from buildings is one of very important issues nowadays. New and renewable energy sources for buildings are especially important when we concern about energy supply for buildings. Among new and renewable energy sources, use of seawater for heating and cooling is an emerging issue for energy conscious building design. The options of energy use from sea water heat sources are using deep sea water for direct cooling with heat exchange facilities, and using surface layer water with heat pump systems. In this study, energy consumptions for an Ice Rink building are analyzed according to the heat sources of air-conditioning systems; existing system and sea water heat source system, in a coastal city, Kangnung. The location of the city Kangnung is good for using both deep sea water which is constant temperature throughout the year less than 2℃, and surface layer water which should be accompanied with heat pump systems. The result shows that using sea water from 200m and 30m under sea lever can save annual energy consumption about 33% of original system and about 10% of that using seawater from 0m depth. Annual energy consumption is similar between the systems with seawater from 200m and 30m. Although the amount of energy saving in summer of the system with 200m depth is higher than that with 30m depth, the requirement of energy in winter of the system with 200m depth is bigger than that with 30m depth.

Many countries have tried to make green building assessment systems, since the importance of sustainability in building industry has been recognized. As leaders of global green building assessment technologies, UK and USA have made their own green building assessment systems, named BREEAM and LEED. Korea has also made a proper building assessment system, named GBCS(Green Building Certification System) and started to implement the GBCS in 2002. BREEAM and LEED have been upgraded as the requirement of society for building industry has been changed. GBCS has also been upgraded and became effective in July 2010. The new system was improved, but still need to be looked carefully for a better performance. The goal of this research is to compare and analyze the three green building rating systems; GBCS, LEED and BREEAM. This study is focused on the suggestions for upgrading GBCS.

The issue of indoor air quality is very important as well as that of energy efficiency for building operation. However, the two issues, indoor air quality and energy consumption, are conflict each other. A proper air quality in a building requires enough ventilation, which leads to increase heating and/or cooling loads. Minimum amount of ventilation for acceptable indoor air quality is very important for solving both indoor air quality and energy efficiency problems. In order to get the targets, ventilation systems usually use automatic control systems. This paper looks at the different automatic control systems for ventilation to get a reasonable indoor air quality. Two similar sized buildings in Busan were chosen to compare the appropriateness of control systems for ventilation. Then the monthly energy consumption of those buildings for a year were investigated. With a similar indoor air quality, energy consumptions for ventilation systems are different according to the automatic control systems. The result might be useful to select an automatic control system for energy efficient ventilation with acceptable indoor air quality.

Recently, alternative energy resources have emerged considerably due to the high oil prices and environment problems. Deep sea water that is one of the natural energy sources can be one of the attractive solutions to reduce the environment problems, and there are already a few examples in some developed countries. In this study, cooling system of deep sea water using heat exchangers of two hotels, located in near Haeundae Bay in Busan, have been analyzed on the quantity of electricity and gas use comparison between existing cooling system and deep seawater cooling system by using E-Quest simulation program. The results of the study showed that the Hotel A approximately saves 370 millions won per year, and the Hotel B saves 248 millions won per year. It means that the cooling system by using deep sea water has great worth to reduce the ratio of fuel sources.

Indoor air contains a complex mixture of bio-aerosols and non-biological particles. Increases in allergic sensitization, the onset of asthma, asthma attacks and bronchia hyper reactivity has been correlated to increased level of specific, biologically based species in building dusts. The improvement of IAQ (Indoor air quality) through the control of bio-aerosol is very important, but it is not well recognized in Korea except those in special facilities such as hospitals and clean rooms. In this study, indoor bio-aerosol measurements are presented from typical elementary schools In Busan, Korea. The education enthusiasm and standards are very high but environmental conditions of classrooms are comparatively low. Since children in classrooms are weak from diseases, classroom where they live for hours should be comfortable and safe. The study of indoor bioaerosol contaminant is new in Korea, and need to have further research since bioaerosol contaminant can cause disease to many people. This study shows the relationships between bioaerosol contaminants and other indoor environmental factors in elementary school classrooms. Also this study can be used as a basic data for improving classroom IAQ conditions.
