This study is purposed on applying to certifying environmental-friendly buildings about remodeling schools as an issue recently, keeping up a worldwide resource conservation movement. Application standard is directed, comparing with systems certifying green-schools in domestic and foreign policies. The following is the primary result of this study. First, on developing systems for certifying environmental-friendly buildings about remodeling schools, characteristics like ‘the phase of certifying essential lists and the diversity of certifying lists’, ‘developing departmentally into new-building, reconstruction, remodeling, existing-building in basic data’, ‘development of certifying existing-buildings as well as new-building’ in foreign systems should be developed appropriately for Korea. Next, not only reuse of the existing facilities but better assessment through diversification of classified contents in domestic system are carried out in comparing remodeling lists. Especially the primary list that is found out commonly limited lists certifying remodeling should be developed appropriately. Impossible lists getting certification should be applied to map out a concrete standard. Lastly, the range of certification should be diversified and developed sustainable like other systems for better assessment. Adding various lists suiting for Korea and departmentalizing score of phases and items in particular, for avoiding a needless collision between certification lists, absence of them. Above of all, basic direction about certifying environmental-friendly buildings about remodeling schools should be developed the only individual instrument, not for gaining it simply as a part of the environmental policy in Korea. This study has significance on vitalization of certifying environmental-friendly buildings, which performing primary environmental-friendly education facilities, based on its advance.

Due to the Climate change and resource shortage by global warming, various problems are rising and getting worse around the world. Many countries are doing the considerable efforts to reduce greenhouse gas emissions. The government of South Korea also plans to decrease greenhouse gas emission, the various pilot projects are underway, which includes obligation of energy efficiency 1st rating and greenhouse gas target management system of public buildings. In particular, luxurious government office buildings and energy-wasting public building have issued and emerged as a social problem. Energy efficiency improvement of the existing public office buildings are becoming an important issue recently. This study is proposed the step-by-step energy improvement model according to the building energy efficiency rate in order to reduce the energy consumption. To attain this end, I set up a base model by analyzing the current architectural conditions of the existing public office buildings and grasped the specific properties of building energy consumption through energy simulations. Furthermore, I suggested phased reduction prototypes for the reduction target of energy consumption by applying the methods of the zero energy building plan. This study is expecting that prototypes would give directions when it comes to planning the implementation policy of phased building plan factors, according the building energy consumption reduction goal in the existing public office buildings which are the subject of building energy target management system.

G-SEED has been introduced with the aim of reducing energy use and resources since 2002, as the system of certificating environmental friendliness of buildings to create comfortable environment. This study analyzed the changes of certification standard of G-SEED since the revision in 2016, comparing certification results of office buildings by grade, category and certification items between G-SEED 2013-2 version and revised version of 2016. Also, this study analyzed the average points and their standard deviation of certification items including both deleted items and newly added items and extracted items needed to be reviewed in the future revision. In the revision, G-SEED has been extended its certification system to involve existing buildings and Innovative Design categories newly introduced with revising the certification items and difficulties. In revised version of G-SEED, the certification grade appeared to change its acquisition ratio decreasing Green2 and increasing Green4, during Green1 and Green3 were similar in proportion. The average scores by categories appeared decrease in Energy and Environmental Pollution category and Materials and Resources category, on the other hand, Maintenance category appeared the highest increase in the average score. Otherwise, Land Use and Transportation, Water Circulation, Ecology, Indoor Environment categories appeared similar average scores both version of G-SEED. In addition, the Innovative Design which was newly introduced category, seems to expect gradual gaining high scores according to technology development in future, although its possession has shown lower scores in revised version.

Currently, the energy consumption rate in buildings is approximately 28.5% of the total energy consumption in Korea. Therefore the amount of the consumption of petroleum resourses is at a worrying level of the blackout. The system of the amount of the Architectural Energy Efficiency Grade [AEEG] is in force by the government to apply the technologies of the Emissions Trading System and the Target Management System to mitigate the Green House Gases for buildings according to the climate change. On the account the mitigation of the Green House Gases and the reduction of the energy, from the view of maintenance and management, for the new and remodeling buildings should be under consideration. The author wants to present the possible ways how to improve the AEEG for the existing buildings by trying to establish the foundation of the BEMs, and by confirming the potential of the energy savings.

Green technologies of buildings are spreading for saving resource and energy consumption during life cycle of buildings. However, selection of optimized the technologies for applying projects is needed a lot of time and costs. Therefore prioritization is necessary to apply the technologies for buildings. An evaluation of economic value for the technologies is significant for prioritization of the technologies, however, the current evaluation system of economic value for technologies is not reflected the accurate features of the technologies. Green technologies have the objectives for reducing the emission of CO2 and saving the cost during the whole lifecycle of buildings. Thus the evaluation of economic feasibility for green technologies is needed to include the economic value from improving the environment. This paper developed the economic evaluation method integrated with LCC and LCA to accurately analyze the economic value for green technologies. Moreover, this paper drew the priority of the technologies by conducting case studies with the integrated method and analyzing the results with AHP. The conclusion of case studies, Green technologies is worth more if to include the economic value from improving the environment. Then in analysis of priority, Green intelligent component technologies were rated the highest. The conclusion of the study is able to utilize the supporting tool for making decision to select the optimized technologies for the projects and precedence study for developing future research of prioritization for green technologies. The future study for improving the developed method will supplement the various evaluation factors and apply the detailed weight to analyze the priority of green technologies.

Humanity is facing a number of serious issues associated with increased energy consumption and environmental pollution. Various studies/guidelines concerning sustainable building construction have suggested solutions to these disastrous problems, including: net-zero energy buildings, the green building certification system, and others. Sustainability pursues three expected effects: environmental, social, and economic merits. Korean Green Building Council (K-GBC) has also announced the Korean Green Building Certification System (K-GBCS) since 2003 based on sustainability. Some positive social and environmental aspects of the K-GBCS have already been reported. However, it is somewhat difficult to verify its economic merits, which are crucial to ensuring the validity of the K-GBCS. This research aims to verify the economic merits of the eco-friendly Korean-style condominiums accredited by K-GBCS. Following this, the expected economic effectiveness of K-GBCS will be examined in terms of sustainability. The underlying assumption is that the potential economic effect should reflect the actual economic merits, and should reflect the value of the housing in particular. According to the analysis of the variance, it can be concluded the value of green certified buildings is statistically higher than the value of non-certified buildings. Furthermore, it was also observed that this tendency was more dominant in Gyeonggi Province than in the City of Seoul. This may be caused by one of the variables: the proximity to downtown. In future studies, this variable should be studied in greater detail.

Purpose: As the concerns for the environment are gradually prioritized, increasing interests of environment-friendly buildings are drawn. The Green Standard for Energy & Environmental Design (G-SEED) has been strengthened. However, there are no specific assessment criteria that reflect the special situation of healthcare facility. UK, US and Japan have green building certifications specially designed to evaluate sustainable healthcare facilities. This study has been started in order to provide basic information for developing assessment criteria for healthcare facilities in Korean Green Standard for Energy and Environmental Design. Methods: In this study, we investigated three foreign green building certifications and compared their assessment system and criteria for healthcare buildings. Results: Each of the three foreign certification standards showed the difference in the system, but all contained the contents specific to healthcare facilities. Evaluation items were affected by regional cultural environment and also medical environment. Patient safety and integrative planning were the most important assessment contents. Implications: Based on this analysis, Korean Green Standard for Energy & Environmental Design for healthcare facilities will be developed.

It is undeniable that urban greenspace is the soul of a city. Conventional urban greenspace such as parks, community gardens, playgrounds etc. located within a city reduce the negative effects of pollution, play a major role in the survival of the urban ecosystem, and promote healthy lifestyles. Today, 55% of the world's population lives in urban areas, which is expected to increase to 68% by 2050. Projections show that urbanization and the gradual migration to urban areas combined with the fast growth of the world's population, could add another 2.5 billion people to urban areas by 2050 and almost 90% of this increase will take place in Asia(UN, 2018). As a result, many plots in the cities are and will continue to be occupied with buildings to provide residential support to the increased population. This will dangerously decrease urban greenspaces. Moreover, worldwide, food crisis, energy crisis, and social crisis is posing a great threat to the existence of mankind. Additionally, the COVID - 19 has introduced a new lifestyle where from work culture to community configuration has drastically transformed. In this scenario, residential buildings will have to serve more than just providing privacy and shelter. As urban greenspaces are being occupied by concrete residential buildings, these buildings will have to compensate for the percentage of urban green they are destroying and the issues they are imposing in the process. The goal of this thesis is to design, architecturally define and, categorize comprehensive 'sustainable Greenspace'(S.G.S) for the multi-family housing scenario. These will be different than the conventional green (veranda, rooftop green) we commonly see in residential buildings. An old, dilapidated apartment building will be the target of remodeling to fulfill the purpose of this thesis.
