세계적인 에너지 및 온난화 문제로 이에 대한 개선은 필연적인 과제가 되었다. 그러나 기존의 대응은 건설단계와 운용단계의 에너지 소비절감에 집중되어 왔다. 상대적으로 유지관리 및 해체 폐기단계의 관리는 소홀하였다. 본 연구에서는 건설 전 생애주기에 걸쳐 각 건설단계 별로 발생하는 환경부하를 정량적으로 예측하여 평가하고, 각 공정별로 환경부하를 평가할 수 있는 시스템을 개발하였다. 또한 건설 전과정에서의 환경부하 평가 및 저감을 위한 객관적이고 신뢰성 있는 의사결정 모델을 제시하였다. 또한 프로그램의 현장 적용성을 검토하기 위해 실제 해체공사를 대상으로 시험평가를 실시하였다. 이를 통해 친환경 건설기술 개발에 일조하고 저탄소 녹색성장에 기여하고자 한다.

The study was conducted to determine greenhouse gas (GHG) inventories in grasslands. After 'Low Carbon Green Growth' was declared a national vision on 2008, Medium-term greenhouse gas reduction was anticipated for 30% reduction compared to Business As Usual (BAU) by 2020. To achieve the reduction targets and prepare to enforce emissions trading (2015), national GHG inventories were measured based on the 1996 Intergovernmental Panel on Climate Change Guidelines (IPCC GL). The national Inventory Report (NIR) of Korea is published every year. Grassland sector measurement was officially added in 2014. GHG removal of grassland soil was measured from 1990 to 2012. Grassland area data of Korea was used for farmland area data in the "Cadastral Statistical Annual Report (1976~2012)". Annual grassland area corresponding to the soil classification was used "Soil classification and commentary in Korea (2011)". Grassland area was divided into 'Grassland remaining Grassland' and 'Land converted to Grassland'. The accumulated variation coefficient was assumed to be the same without time series changes in grassland remaining grassland. Therefore, GHG removal of soil carbon was calculated as zero (0) in grassland remaining grassland. Since the grassland area increases constantly, the grassland soil sinks constantly . However, the land converted to grassland area continued to decrease and GHG removal of soil carbon was reduced. In 2012 (127.35Gg $CO_2$), this removal decreased by 76% compared to 1990 (535.71 Gg $CO_2$). GHG sinks are only grasslands and woodlands. The GHG removaled in grasslands was very small, accounting for 0.2% of the total. However, the study provides value by identifying grasslands as GHG sinks along with forests.

The international community is paying close attention to the climatic changes caused by the meteorological anomalies. In response to such phenomena, after the adoption of the United Nations Framework Convention on Climate Change in 1992, efforts to actively respond to the meteorological changes are proliferating all over the world; even in the Republic of Korea, the issue to tackle the meteorological changes has emerged as a top-priority national agenda. In the year of 2008, after the declaration of the low-carbon, green-growth paradigm by the government, the UNFCCC COP15 has announced a 30% reduction target of the emission of the greenhouse gases by 2020 as compared to the "Business As Usual, BAU" and has also confirmed, as a commitment plan to achieve reduction in the emission of greenhouse gases, the reduction target of greenhouse gases for all sectors, industries and years. (26.9% for buildings) Since the construction of the new apartment houses in the year of 2001, the "Building Energy Efficiency Rating", has been applied to newly constructed building complexes, built in 2010; the accumulated emission reduction has been evaluated at around 450,000toe and the accumulated carbon dioxide emission reduction is at $826,000tCO_2$ And through the prediction of these values under various scenarios (New construction, new construction / expansion of existing uses, when transferred to 1stgrade), the effects on the degree of reduction of greenhouse gases by the increased certification of the Building Energy Efficiency Rating are an alyzed and it is our aim to express the importance of the certification system capable of carrying out a quantitative evaluation of the building energy in order to establish the strategy to reduce the emission of carbon dioxide.

전 지구적으로 이산화탄소 증가에 따른 지구 온난화가 화두로 떠오른 지는 30년이 넘었다. 최근 정부는 저탄소 녹색성장 기본법 시행령을 발표하고 이산화탄소증가를 방지하기 위한 세계기후변화 협약 등 에너지 절약과 이산화탄소 배출 감소에 대한 노력을 지속적으로 실행하고 있다. 하지만 대다수의 도시들은 에너지 절약관점에서 계획되지 않기 때문에 새롭게 계획되는 도시는 장기적인 관점에서 '지속가능한 도시개발'을 위해 능동적 에너지 절약형 도시구조로의 전환이 필수적이다. 본 연구는 4차산업혁명의 시대에 새로운 국가 비전인 지속 가능한 에너지 자립형 친환경 주거단지의 새로운 프로토타입을 설정하고 향후 하고자 한다. 에너지 자립형 단지계획과 단지계획요소의 정량적 표준화에 대한 연구를 진행하고자 한다.

As landscaping building roofs and concrete structures increase gradually for low carbon green growth policy of government, But waterproofing membranes of those structures are effecting by root penetration of landscape plant. 80, we progressed study about test method for fast evaluating root resistance of waterproofing materials jointly with Tokyo Institute of Technology. The result of the study is as follows: (1) The penetrating load of the needle at the displacement speed of 1mm/min was measured for various membrane to basis and lap joints of membrane, the load force was $3{\sim}50$ N by material variously. (2) According to the test method of deriving rhizomes of bamboo grass to basis and lap joints of membrane, there were no penetrated membrane until present, but need persistent observation. (3) Test method of deriving rhizomes of bamboo grass to basis and lap joints of membrane can shorten from period of 2 years to 1 year for testing. Because rhizomes of bamboo grass can grow from May to September, test is possible in same period.

At the product design and development stage, the main criteria selecting a design alternative were performance aspect as well as cost aspect of a product. Ongoing new paradigm shifts such as low carbon green growth, climate change mitigation, sustainable society development urged considering environmental aspect of a product at the product design and development stage. Up to recently, only cost aspect except performance of a product was considered at the railway vehicle design process. Therefore, it is needed to develop a method that may consider environmental aspect of a product at the railway vehicle design process. Lee (2011) proposed that a method of an integration assessment of environmental aspect and cost aspect based on GHG emission instead of based on monetary value. This study conducted that apply the method of Lee (2011) to design alternative selection process of a railway vehicle. From the integrated view of environmental and cost aspect, the reference product and design alternatives are assessed and compared.

As a public transit playing an important role in the era of high gas prices, subway corresponds the national strategy 'Low carbon, Green growth'; accordingly, passengers who would use the transportation are steadily increasing. Subway operators are required to provide subway users with services based on higher-quality system, safety, convenience & high reliability level. Furthermore, as the legally allowed maximum life time of EMUs is extended, it is necessary to localize & standardize the parts of EMUs. This paper presents a modelling of systematic EMU(SR001) manufacturing technique which enables us to reflect passenger and subway operator's demands in the whole EMU manufacturing process from the initial design phase to its completion by making full use of the know-how based on subway operators' experiences. SR001 enabled SMRT's staffs to participate in the EMU design & its equipment manufacturing; consequently, it realized the innovative system which meets passengers' requirements. Moreover, the process lead time was reduced dramatically. The result of this research will be helpful in providing useful guidelines for railway industry policy and development making in Korea.

Since the "Low Carbon, Green Growth" as a social requirements is attracted public attention, the policies and investments of the railway which have been less estimated than road is re-considered. Since the starting the commercial service (2004. April), the KTX have been operated successfully while transport passengers over 100million for years. And also the project for development of KHST (Korea High Speed Train ; G7) had been accomplished with a good result, the first trainset of KTX-II which base on G7 project was manufactured and testing now. On the other hand, the world's technology of the high speed train is more faster, and changing to a distributed traction system. To catch up the world's leading technology, the HEMU(High-speed Electric Multiple Unit) project will secure new technology and aims to promote the technology of domestic high-speed train. The authors indicates the result of detail review such as a curve, slope of the track and electrical dead section of the catenary to test at 400kph and also the performance simulation of the developed rolling stock in this paper. As the result, the authors devise the test scenario to perform a maximum speed test (stability at max. speed, acceleration & deceleration etc) with the restricted conditions such as track length, track available time etc by considering above result.
