The South Korean government plans for a 37 % reduction in CO2 emissions against business as usual by 2030. Subsequently, the Ministry of Land, Infrastructure and Transport declared a 26.9 % reduction target in greenhouse gas emissions from buildings by 2020 and established the Green Standard for Energy and Environmental Design (G-SEED) to help improve the environmental performance of buildings. Construction companies often work with consulting firms to prepare for G-SEED certification. In the process, owing to inefficient data sharing and work connections, it is difficult to achieve economic efficiency and obtain certification. The objective of this study was to develop an economic model to assist contractors in achieving the required G-SEED scores for materials and resources. To do this, we automated the process for material comparison and selection on the basis of an analysis of actual consulting data, and developed a model that selects material alternatives that can meet the required scores at a minimum cost. Information on materials is input by applying a genetic algorithm to the optimization of alternatives. When the model was applied to actual data, the construction cost could be lowered by 79.3 % compared with existing methods. The economical material selection model is expected to not only reduce construction costs for owners desiring G-SEED certification but also shorten the project design time.

This research aims to predict and analyze green building certification market of Korean Peninsula after unification. First, it analyzes prospected unification time period, then it forecasts number of new residential and non-residential buildings to be constructed based on estimated number of residences in short at the time in North Korea. There exists a good chance that North Korea's new building market forms similar to that of South Korea, as unification would thoroughly proceed which would result levels of economic culture social politics in quasi-equal state. Thus, assuming the ratio of residential and non-residential building against population is similar in both Korea's, the number against North Korea's house supplied population can be estimated. Based on the expected numbers in North Korea, number of proceeded Building Energy Conservation Plan, Building Energy Rating Certification, and Green Standard for Energy and Environmental Design (G-SEED) are predicted. The research shows certification market related to green building in united Korean Peninsula to be \660 billion over 10 years. Not only certifications to newly built buildings but also including existing buildings, this market is to grow to a considerable extent. As this would largely influence eco-constructive materials, energy plant/equipment, and other relevant markets as well, it would require to make thorough preparations. In sum, to stabilize green building market even before the unification, the research proposes the necessities of appropriate systems in consideration of North Korea, through in-depth discussions and establishment of technology and policy directions in green building sector, such as building energy management and emission reduction technology.

Song-do City is a newly constructed city built on land reclaimed from the seaside and the surrounding area. Its development involved a long process since the basic plans for reclamation of the publicly owned seaside area in Song-do were drawn up in September 1979. However, if we take a look at the overall status of the project as it is carried on at present, it is hard to deny that the project is trapped inside the same legal restrictions as are all other existing cities, which permits Song-do City to meet only very minimum standards. This study intends to analyze and assess the Song-do City's environmentally friendly construction and to rate its current development status, exposing any problems and offering alternative solutions. In this paper, the current state of constructions in Song-do City were reviewed. Then a quantitative analysis and assessment for the Song-do City constructions of apartments, complex buildings, office buildings, and school facilities were conducted by using green building certification criteria. Finally the synthetic results of environmental performance evaluation for Song-do city constructions and follow-up suggestions were described.

This study is lately stand on the basis of the importance for global warming and environment and accept changes of the paradigm of the 21st century. also it is to start architecturial access that suggest to solutions about environment, energy and health problems in high-rise residential architecture that lately the importance for global warming and environment. Spacially since 1990, high-rise residential architecture has developed into increase rapidly, and nowdays, this has become one of the new residence type. but this have diverse problems. For this reason, this building faced neccessary to improve living space and obtain to eco-friendiness and sustainability. Therefore, this study is focused to environment-friendly architectural certification in Korea and other countries, aims to suggest planning and technical elements from this system. Through 11 cases of high-rise residential architecture certified sustainable certification system, this study drew out tendency and charateristics of main strategy elements. These analysis will express informations of current level and also suggest to direction for improvement in quality of high-rise residence.

The seriousness of greenhouse gas exhaustions and energy use of the building has increased, the world is making an effort with many requests and the consultation for sustainable development. For this reason, Green Building Certification Criteria has been implemented to reduce environmental load, high-performance and environmentally friendly in the United States, the United Kingdom and Germany. In response to the global trend like this, the Korean Government has induced the eco-friendly construction and sustainable development to implement the G-SEED (Green Building Certification Criteria of Korea) in 2002. However, in spite of the many authentication result, G-SEED has been pointed out that it needs for improve in the evaluation system of Apartment sector which accounts for more than 40% of the authentication. Therefore, the purpose of this study is to suggest improvements in the evaluation system. To achieve this, this study have selected for LEED, BREEAM, DGNB of comparison target, drawn improvements through comparing transition process in G-SEED.

Until now, measures for energy saving in buildings have been tried. Because particularly the role of buildings area is very important for implementing national greenhouse gas reduction targets and Green growth. But, lack of business linkages between each sector or the interest and participation of private sector are not enough. In addition, relevant personnel to do had not been systematized. It is expected that certification services will be increased according to the activation of Building Energy Efficiency Rating System and expansion of the target buildings so Government must be prepared to expand of certification system by training Professional staff. In this study, the basic data for the introduction of obligation of Building Energy Efficiency Rating System is suggested through analysis of the operating and laws system of Building Energy Efficiency Rating System along with efforts of Government for diffusion low energy buildings.

G-SEED's evaluation of existing buildings is an important point because the energy consumption and CO2 emissions of existing buildings are continuously increasing due to the aging of buildings over time. However, as G-SEED certification is concentrated on new buildings and the standards are not yet available, we will make improvements to evaluate the existing buildings of G-SEED. In order to improve G-SEED for EB, two research procedures were carried out. First, LEED EBOM and LEED for NC compare and analyze evaluation items and methods, and LEED EBOM focuses on evaluation of existing buildings. Second, we analyzed the certification evaluation contents of eight domestic LEED EBOM accredited buildings and obtained items that can be applied or need to be applied when revising G-SEED for EB. LEED EBOM is focused on improving the performance and utilization of data that track and manage the energy and environmental effects of building operations. As a result of the case analysis, the evaluation of G-SEED for EB requires quantitative evaluation items such as environmental management of buildings, energy performance status of building, improvement plan and improvement of performance according to tracking value. Although G-SEED for EB is not structured yet and there are few cases of certification, it is expected that quantitative evaluation of existing buildings will be made through continuous research.

Presently, various building certification systems are being enforced in Korea. However, people are in confusion and have an aptitude to waste time and money because these certification systems for buildings have very similar criteria. After investigating the foreign certification systems and domestic certification systems for the building, it is required that some of similar building certification systems are integrated.
