Purpose: Medical center has consumed the energy about twice the average value of building types. So, many countries have tried sustainability and energy reduction for building types through eco friendly certificate. This study investigate the eco friendly building certificate and energy performance certificate focusing in UK and Korea, and search the characteristics of status and services of certificates. Methods: BREEAM openbook and EPC open data have been studied in UK, and green building performance certificate and EPC data in korea have been analyzed. Results: UK has eco friendly building certificate focusing on healthcare, and EPC shows the standard, benchmark reference value, so lead to the CO₂ emission reduction. Primary health center and hospital show the higher value due to the dwelling unit. like a patient bed. Korea doesn't have green building certificate yet on healthcare, and EPC shows not the reference data, but the primary energy consumption. Korean cases just like in UK, clinic, public health, and outpatient center show the lower value compared to medical center, nursing home and general hospital. Implications: In Korea, it is needed for energy efficiency to have reference data information like a standard and benchmarking value for new design and construction.

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 Green growth has been demanded in all industrial sectors due to environmental destruction and exhaustion of natural resources. Buildings have consumed 1/3 of the total energy and 40% of natural resources and have accounted for 50% of $CO_2$ emissions and 30-50% of waste materials. In 1991, BREEAM(Building Research Establishment Environmental Assessment Method) of the British BRE(Building Research Establishment) had begun reduction of $CO_2$ emissions and energy saving movements, in which all the countries around the world have participated. The Republic of Korea has taken part in this trend by declaring a "National Vision in the Green Growth" in 2008 and implementing regulations on "Low Carbon, Green Growth" in 2010. G-SEED(Green Standard for Energy and Environmental Design) based on GBCS(Green Building Certification System) has been actively promoted for its application. This study has limited its scope to G-SEED office buildings. It has conducted surveys of problems and assessment items of the G-SEED identified in the preceding study by the AHP(Analytic hierarchy process) method. The purpose of this study is to conduct a comparison analysis of problems and ranking of evaluation items recognized in the survey and to be presented as reference materials for G-SEED system improvements at its next amendments.

The building construction sector has been blamed as the main culprit of environmental contamination worldwide. So, there shall be some constructive alternatives in architectural engineering. As one of the alternatives, the LEED ("Leadership in Energy and Environmental Design") has been introduced since 1990s and has been well recognized in saving the resources and energy. "LEED" has also been introduced in Korea since 2002 but it has not put priority on the eco-friendliness of indoor space. In this study, the international and domestic green systems were analyzed and compared in order to restructure the checklist for indoor space. Using the restructured checklists, the questionnaire were sent to 180 people using 6 office buildings which passed the domestic "LEED" certification. LEED certification system put priority on the air quality and heating/cooling environment in its evaluation section and items. However, according to the results of the study, it was found that the people using the buildings were not satisfied enough with the air environment of buildings along with their other indoor environment items. This shows that even though the office buildings are designed according to the requirements of LEED, the buildings do not meet the occupier's needs. In addition, it showed that the evaluation items should be improved so that they are useful to enhance the satisfaction of the occupiers' needs. The paper could be useful in establishing standard for eco friendliness of indoor space of office buildings which pass the LEED certification as the basic data for increasing energy efficiency and working efficiency of occupiers of the buildings.

Purpose: Numerous researches about healthcare buildings have been performed however, they were mainly focused on convenience or healing condition for medical treatments. The hospitals consume energy and generate $CO_2$ as twice as the residential or commercial buildings do(Lim, et al., 2010a:154). The public regional hospitals are especially in serious conditions. They are more than 20 years old in average. Energy efficiency and environmental friendliness in the public regional hospitals are far behind ones in private sectors. Even though the ministry of health & welfare is supporting renovation of the builidngs and enhancement of the facilities every year, it is not integrated including sustainibility. In this study, we investigates current conditions of the regional public hospital in envrionment-friendly standpoint, especially focused on Chungcheong Province area Hospitals. Methods: we investigates current conditions of the regional public hospital in envrionment-friendly standpoint, especially focused on Chungcheong Province area Hospitals. The study was executed by qualitative and quantitative evaluations with site inspection, drawing analysis and interviews. Results: Through this study, we found that the Chungnam regional public hospitals can be environmentally improved by management plans and programs. Implications: Based on this analysis, Korean Green Building Certification for healthcare facilities will be developed in near future.

The purpose of this study is to extract environment-friendly planning elements to apply in Korea by putting together and reclassifying four foreign environment-friendly certification systems related to regeneration spaces - LEED in USA, CASBEE in Japan, BREEAM in England and BEAM in Hong Kong - and analyze and evaluate domestic and foreign spaces which were certified as Environment-friendly spaces in order to offer plan guidelines to raise awareness of the importance of environment-friendly elements in regeneration spaces and to encourage them. The concept and the characteristics of green building were studied through documentary survey. In addition, green certification system of the present domestic new spaces and foreign regeneration spaces was studied and assessment tools for indoor regenerated spaces-related green certification system were developed. With checklists which are developed in this study, level of going green of foreign spaces certified environment-friendly was assessed. Based on the results of this study, conclusions are as follows. As a result of case research of spaces-certified green of Hong-Kong's existing buildings with a developed checklist, application of general assessment part was all alike, but that of detailed assessment part was different. However, Hong Kong showed superiority in lighting energy saving, separate collection of recyclable domestic waste, recycling by-product and management. In addition, Hong Kong applied eco-friendly planning elements maintaining buildings in their condition as possible as it could with management, use of green program, replacement with high efficiency lighting, monitoring system, installation of recycling bins and energy saving by attaching reflective film.

SWG(Smart Water Grid)는 한정적인 수자원을 효율적으로 이용하고 사용자 입맛에 맞춰 물을 안정적으로 공급하고자 하는 양방향 개념으로 수자원 분야에서 각광받는 실정이다. SWG의 성능을 평가하는 연구사례는 많지 않으며 현재 국내의 경우 실증단지를 구축하고 있는 단계이다. 그러므로 성능평가를 수행하기 위한 실측자료가 부재하므로 성능평가 지표선정에 활용 할 수 있는 자료가 제한적이다. 따라서 미국의 Leed, 영국의 BREEAM, 일본의 CASBEE, 호주의 Green Star의 인증 기준에서 수자원에 대한 항목과 기존의 IWA, World Bank, AWWA, JWWA, OFWAT 같은 해외 상수도 수행능 지표와 상수도 및 정수장 기술진단에서 제시하는 기준을 바탕으로 성능평가지표를 선정 보완하여 Water Facility Index, Smart Index, Optimum System Index로 분류하여 각 세부의 성능평가지표를 선정하였다. 선정된 지표는 AHP기법를 활용하여 1-4단계에 걸쳐 계층화를 실시하고 Bottom-up방식으로 4단계에서부터 1단계로 평가를 진행하도록 구성했다. 4단계에서는 계층 별 쌍대비교 결과를 바탕으로 중요도에 따른 가중치를 부여하고 차등 점수를 적용하며, 이는 3단계에서 필수적으로 만족해야하는 지표들을 설정하고 평가하기 위해 사용된다. 3단계에서는 지표평가 후 "보통" 이상의 점수를 획득해야 2단계로 진행할 수 있고, 2단계에서는 3가지 큰 지표를 설정 후 총점 기준 60%이상의 최소득점 기준을 만족해야 1단계로 진행할 수 있도록 구성했다. 이러한 절차를 바탕으로 마지막 1단계에서는 100점을 만점으로 하는 6단계의 최종성능을 평가하는 결과를 제시할 수 있다. 본 연구에서는 국외 성능평가 사례 중 SWG와 관련된 지표를 구성하여 성능평가를 수행할 수 있는 기법을 제안하였다. 향후 지속적인 연구 진행 결과와 실측자료를 수집하여 수정 및 보완이 수행될 예정이다.

An apartment complex is a building use with great potential to contribute to solving problems related to urban ecological environment and climate change. The first goal of this study is to grasp the current situation of application and limitations of the ecological area rate, which is a representative evaluation index used to evaluate the environmental performance of the external space of an apartment complex in Green Standard for Energy and Environmental Design (G-SEED). The second goal is to propose a prototype of the evaluation index for evaluating greenhouse gas (GHG) reduction performance in order to supplement the evaluation index for the environmental performance of the external space in terms of response to climate change. We analyzed 43 cases of apartment complexes certified according to G-SEED, which was enforced since July 1, 2010, and found application characteristics of each space type and the limitations of ecological area rate. We analyzed overseas green building certification systems such as LEED and BREEAM that derived implications for supplementing the limitations of ecological area rate, which is focused on the evaluation of soil and water circulation function, and set up a development direction of complementary measures. Through analysis of previous studies, relevant regulations and standards, and technical documents of the manufacturer, the heat island mitigation performance of the pavement and roof surfaces of the apartment complex and the carbon uptake performance of the trees in the apartment complex was selected as parameters to yield the GHG reduction performance of the external space of the apartment complex. Finally, a quantitative evaluation method for each parameter and a prototype of the evaluation index for the GHG reduction performance were proposed. As a result of applying the prototype to an apartment complex case, the possibility of adoption and applicability as an evaluation index of G-SEED were proved.
