The introduction of strategic environmental assessment (SEA) has strengthened and extended the value of environmental impact assessment (EIA) as a foundational tool for sustainable development. In particular, SEA helps to overcome the limitation of project EIA as a 'stand alone' approach, applied relatively late in the decision making cycle. SEA is applied to policy, plan and programme (3P) proposals, when major alternatives are open and systematic consideration can be given to their environmental effects. This process also corresponds to options appraisal of development proposal to find the best practical outcome having regard to all potential impacts. There are imperatives for sustainable development (SD) that are shaping future directions for EIA and SEA internationally, regionally and locally. There is a shift toward more integrative approaches of using EIA and SEA as sustainability tools in cooperated environmental management system (EMS). Korea has established and applied EIA for over twenty years for various projects. Given its coverage, the current EIA system is SEA exclusive. The Prior Environmental Review System (PERS), which is a SEA-type of system, was applied in the late 1990s, mainly for various developing planning programs. The current PERS has been modified as a SEA type system, but in general, policy is not going to be covered.

Environmental issues have become gradually important around the globe, which has increased society needs for the environment-friendly construction. In an effort to realize the environmental protection and energy efficiency, the British BREEAM has been developed, which is followed by the USA LEED, Japanese CASBEE and other national certification systems based on their own conditions. In this end, the Republic of Korea has implemented its own certification system named GBCS(Green Building Certification System) in 2002, and now actively promoted the G-SEED(Green Standard for Energy and Environmental Design) after GBCS modifications and amendments. The purpose of this study is to identify possible problems to be encountered in the process of the G-SEED for office facilities and to provide relevant solutions. In this end, three office facilities have been selected, which had obtained the G-SEED. This study has analyzed reasons of change of assessment scores between the preliminary certification and the main certification phases, has identified problems through in-depth interviews with practicing professionals(design, construction, eco-friendly consulting firm) and then has reached a conclusion for improvements. This study will be possibly used as reference materials for improvements of the green building certification system, and further detailed studies on respective parts will be required for improvements.

The new paradigm called 'Low Carbon Green Growth' involved in reducing greenhouse gas is on the rise as a critical issue worldwide. The essential of Kyoto protocol issued in 1997 is to achieve the sustainable economic growth environments by converting existing production system to eco-friendly one. The protocol imposes the liability to reduce greenhouse gas to the countries joined to it. The paradigm is directly involved in the energy consumption and environmental pollution caused by construction activities. Value Engineering which are mainly applied in the design phase in practice is a measure to improve the value of a constructed facility by analyzing and/or appraising the functions and costs of it. However, an appropriate method which assesses eco-friendliness of constructed facility has not been propose by researchers. This paper proposes a method which assesses the performance involved in eco-friendliness of constructed facility using Value Engineering (VE) in the design phase. The method estimates the environmental cost relative to the amounts of energy consumption and environmental pollution occurred over the entire project life cycle. The database called "Life Cycle Inventory DB", which stores information about the amounts of environmental pollution, is used. The algorithm which retrieves the amounts of environmental pollutions from the DB and converts them into environmental costs is developed. The algorithm is implemented into a system which quantifies the eco-friendliness of constructed facility in the design phase using VE.

In 1991, the ministry of Gov't. Administration and Home Affairs set up a minimum of one sewage disposal plant in each province. By 1995, 264 models of the capillary infiltration method were set up in 331(78%) villages and the contact oxidation method was set up in 52 places. Since the Gov't. sent a letter to each responsible officer across the country stating their disapproval of the capillary infiltration method, the environmentally friendly sewage disposal system has not been diffused. The current model(mechanical sewage disposal) being used, in agricultural and fishing villages, costs too much for maintenance and operation(\50,000 per capita per year). In particular, because of the difference in sewage characteristics of agricultural and fishing villages from urban sewage, the efficiency of the disposal system is very low. Also, because of the growing need for more disposal plants, the Gov't. is looking for cheaper alternatives. This study has analyzed 2 kinds of sewage disposal. The first is used widely in agricultural and fishing villages in Germany. The second is used widely in similar areas of Korea. It has intended to analyze the characteristics, merits and defects of the sewage disposal water plants and pebbles model which is used widely in Germany and developed compatibly for Korea.

This study is focused on the operation of truck with conscious for environmental logistics system to reduce empty truck movements, and to control running empty truck. With the logistics function, road transport represents the biggest environmental threat. Using nonrenewable natural resources, contributing to air and noise pollution, trucks are environmentally unfriendly. Any steps to reduce transport activity will help minimize negative impact. In particular, noxious emissions must be reduced, but in the long term more environmentally friendly vehicles are required.

The applicability of rice husk fiber as a raw material for eco-friendly pulp mold was evaluated in this study. The higher demand of environmental friendly packaging material resulted in the more interest for the natural fiber based pulp mold. The rice husk which is an abundant agricultural byproduct in Asia could be defiberized by an alkaline digestion process. The changes in the pulp mold making process and the properties of pulp mold by the addition of the rice husk were investigated. The addition of rice husk fiber to the pulp mold made with OCC or UBKP resulted in the increase in drainage at the pulp mold forming process. In case of UBKP pulp mold, the addition of rice husk fiber increased the drying efficiency after pulp mold forming since the structure of pulp mold became more bulkier by the addition of the rice husk fiber. Those results showed the rice husk fiber could be applied to the pulp mold manufacturing as one of the eco-friendly natural fiber resources.

The purpose of this study is to suggest a direction for eco-friendly healing space design for healthcare facilities in the future. Theoretical review and case study on the concept of sustainable design, spatial expression and behavioral affordance were used as research method. Through these reviews, the 3 elements of the total healing environment -physical, psychological and social- have correspondence with elements of spatial expression; Refuge, Flow, Prospect and Void. And these are related to the eight kinds of Behavioral affordance which are subdivided into WORK&STUDY, REST, CIRCULATION, VISUAL SEQUENCE, SOCIAL EXCHANGE, REFRESHMENT, COMMUNITY and MEDITATION. And the concept of sustainable design consists of 6 principles ; Natural system, People, Place, The cycle of life, Energy & natural resources and Process. Through correlation analysis of behavioral affordance and 6 principles, the result of this study presents that the physical elements of the total healing space was mainly associated with the principles of people, place and the cycle of life. Psychological element was related to principle of natural system, human, place and process. And social element was associated with the principles of human, place and process. According to this analysis, the case study of four low-rise eco-friendly medical facilities was undertaken. Sustainability was evaluated in total healing environmental through this case study.
