Due to the global warming, the restriction for emitting the green-house gas is strengthened and a main ingredient of the green-house gas is carbon dioxide ($CO_2$). In order to reduce the amount of $CO_2$, the low-carbon and long-life of the construction and the construction materials management system based on the radio frequency identification (RFID) technique have been actively studied in the construction field. The conventional construction management system based on RFID only focuses on the study and experiment for managing the used amount and location of the construction materials in the construction stage, but it does not consider the study for the status management system for the recycling materials in the construction stage or the building deactivation. In this paper, we propose the effective RFID system for managing the status of the construction materials during the construction stage or the building deactivation. Employing RFID with the frequency of 900MHz, the proposed system consists of the reader unit, communication unit, and memory unit, and its tags are attached in the surface or inside of the construction materials.

In October 2009, the Ministry of Land Transport and Maritime Affairs noticed 'Environment-friendly housing construction standards and performance' to build energy saving environment-friendly housings (Green Homes) for the reduction of energy consumption and carbon dioxide emission. In this study, the $CO_2$ emissions were evaluated during the life cycle of the existing apartments which were built in 1980's and Green Home apartment. $LCCO_2$ was evaluated by dividing the life cycle into three stages which are construction, maintenance and destruction stage. $CO_2$ emission from the materials for improving insulation performance was estimated by Input-output analysis. As a result, in 40 year-life cycle of $84\;m^2$ apartment, 400.68 T-$CO_2$ was emitted from 1980's apartment, on the other hand 231.02 T-$CO_2$ was emitted from Green Home apartment.

The advancements of the society aggravate ecological problems, and it is at a point where our living environment is under a serious threat. To resolve such problems, environmental friendly design concepts are evolving through various naming conventions such as conservation of global environment, environmental symbiosis, friendly environmental, nature-friendly, environmental friendly type, green building and eco-construction. Accordingly, in this research, for the purposes of healthy living environmental construction, nature as the subject of its design and highly praised as a new design arena, floral art design theory and its functions, as well as its examples are explored. With the Information available, I was able to confirm that, in interior decorating, floral art design is used as a tool for expressing environmental friendly space, and gradually its necessity and the scope of its application have been broadened. Therefore, utilization of floral art design is to fabricate environmental friendly interior space; and it is expected as a substitute for accomplishing green amenity, and its study should continue for the years to come.

This study aims to understand the environmental impact reduction of green buildings that are certified by Green standard for energy and environmental design(G-SEED). To ensure this end, this study assessed and compared the environmental impacts(global warning, ozone layer depletion, acidification, and eutrophication) of a G-SEED-certified elementary school building(green building) and an uncertified elementary school building(traditional building) using the life cycle assessment methodology. This study considered the environmental impacts from the material manufacturing, material transportation, on-site construction, and operation during 40 years. The comparison of the environmental impact intensity of two buildings showed that the green building generated much more environmental impacts than the traditional building. For example, the global warming potential of the green building was approximately 12.5% higher than of the traditional building since the global warming potential of the green building was 3.751 $t-CO_2eq./m^2$ while that of the traditional building was 3.282 $t-CO_2eq./m^2$. It signifies that the G-SEED doesn't guarantee the reduction of the environmental impacts in terms of four impact categories. Therefore, the G-SEED should be complemented and improved to achieve the environmental impact reduction.

The Basic Act on Low Carbon Green Growth is particularly important because it establishes the basis for climate change policies and replaces Sustainable Development as a directive idea for all environmental policies and regulations. But there still remain some legal and administrative task to shape the relationship with other laws and international codes. This study aims to propose the fact that the Leadership in Energy and Environmental Design should be involved at the Basic Act.

The government encourages adoption of Rahmen structure design to ensure efficient management of national resources. However, in comparison with bearing-wall structure, Rahmen structure requires higher unit construction cost and present challenges in terms of securing adequate floor area ratio and floor height. That is why project clients have been disinterested in adoption of Rahmen structure design. Therefore, we have attempted to find factors having influence on decline of project viability for Rahmen structure. This study will be utilized as a basic reference study for promotion of Green Frame design which is a composite PC structure already developed.

A Green Frame is a composite Rahmen precast concrete structure that utilizes the advantages of the steel frame and the reinforced concrete. Compared to bearing wall structure, the precast concrete structure may raise construction cost If the precast concrete members are produced in plant. Thus, if the precast concrete members can be produced in site, the cost-effectiveness and quality shall be increased. Various site conditions must be considered and reviewed to ensure a space for the in-situ production. Therefore, this study focuses on the basic study on the arrangement of in-situ production module of composite precast concrete members.

Sustainability is becoming more and more important in our everyday lives. Thus, it is apparent that more sustainable initiatives are incorporated in a building design concept to reduce operation costs and environmental impacts. However, will the construction cost go up if the building is going green - especially if it is a tall building? This is the question on everyone's mind. In the following paragraphs, we will look into a case study of a skyscraper in Nanning, China. That 411-metre skyscraper, Nanning China Resources Centre East Office Tower, is currently under construction. Designed to LEED-CS Gold standards, the building has adopted a number of sustainable design elements and operation practice, which indeed only accounts for a small percentage of the total construction cost.

The bearing wall apartments which occupy the majority of multi-residential apartment buildings built in Korea, are known for having limited architectural plan flexibility, posing challenges in terms of maintenance and remodeling. The economic losses and environmental issues resulting from the reconstruction of bearing wall apartments are now accumulating to the extent that they are becoming a national concern. Multi-residential apartment buildings, which are now the dominant form of residence in Korea, must accommodate diverse customer needs and changes in life style. A new concept of Rahmen structure with architectural flexibility is Green Frame. GF multi-residence housing is expected to reduce construction costs and shorten the construction schedule by overcoming the shortcomings of conventional bearing wall apartments. This goal is consistent with the national policies that target the reduction of resource and energy consumption. In addition, GF will be established as a core contributor to achieving a reduction in $CO_2$ emissions, which will enable the sustainable growth of domestic construction industry, and address the low-carbon green growth drive implemented by the government.
