Green Standard for Energy and Environmental Design(G-SEED) has been implemented for the realization of sustainable development and resource-saving and eco-friendly buildings from 2002. Studies about the green buildings are made actively and is being developed through constant revision. However, study results of green building have not been fully reflected in the standard. Therefore, this study analyzes the previous studies about G-SEED for school facilities and check the degree of to reflect the problems and improvements suggested in previous studies. This study will be a reference of future revision Substantial problems and requirements are not reflected in revision standard. Proposed improvement requirements are classed as to improve the items(establish specific standards, supplementation), strengthen standards(designate the prerequisite items), propose a new evaluation method, add new items. delete exist items and adjust the score. Therefore, future revision of G-SEED for school facilities should reflect the results of previous studies.

Based on basic studies on the current status index of BF certification application for school facilities according to the BF certification implementation, this study sought to improve the direction of the different BF certification evaluation indexes for school facilities by investigating and analyzing the status of BF Reservation Certification for elementary schools. A comparative analysis of the status and evaluation indexes of 30 elementary schools in the Gyeongsang region that included indicators of external and internal facilities, sanitary facilities, guidance facilities, and other facilities indicated that school facilities are insufficient to discriminate based on criteria and thus need to be updated for accurate grading. For school facilities that are open for anyone to use, quality improvement should be induced by improving standards and adjusting points for items that earn middle and lower grades.

도시에 불투수면적이 증가하고, 기후변화가 극심해져감에 따라 홍수 및 열섬현상과 같은 도시의 물 문제가 발생하고 있다. 이를 해결하기 위한 정책의 일환으로 우리나라의 녹색건축인증제도(Green Standard for Energy and Environmental Design, G-SEED)에서는 물순환 관리를 평가하고 있다. 하지만, 현재 G-SEED의 평가방법을 살펴보면 빗물관리시설의 설치 정도로 평가하고 있고, 강우 특성 또한 고려되고 있지 않다. 그러므로 본 연구에서는 G-SEED의 빗물관리 및 이용 항목에 대해 수문 모델을 통해 효과를 정량화함으로써 성능에 따라 평가할 수 있는 방법을 제안하였다. 빗물관리 항목에서는 유출저감률을, 빗물이용 항목에서는 빗물이용률을 평가지표로 선정하였고, 각 평가인자를 산출하기 위하여 개념모델을 적용하였다. 빗물이용시설의 경우 초기우수배제장치 용량과 필터 효율에 따른 빗물유입량의 변화와 급수인원에 따른 수요량 변화를 고려한 수문모델을 개발하였고, 수요량과 빗물저장조 용량에 따른 유출저감률과 빗물이용률을 알아보기 위해 MATLAB을 이용하여 모의해보았다. 또한, 옥상녹화의 경우에는 강우, 저류, 증발산, 유출을 고려한 수문흐름모델을 적용하였고, 토층의 두께와 배수(저장) 층의 용량에 따라 모의하여 평가기준을 선정하였다. 제안된 수문모델의 검증을 위하여 서울대학교 기숙사와 35동 옥상녹화의 실측데이터를 비교하였고, 적용성 평가를 위해 RMSE(Root Mean Square Error)와 NSE(Nash-Sutcliffe Efficiency)를 이용하였다. 본 연구에서 제안된 방법을 통해 빗물관리시설의 수문학적 성능에 따른 평가가 가능해질 것이며 설계자와 건축가들로 하여금 실질적인 효과를 내는 시설을 설치하게끔 유도할 수 있을 것이다.

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.

Recently, there are effects such as commercial investment and introducing new technology by introducing a BTL project. As a result, School's conditions are getting better and Numbers of certified schools are increasing, because the Green Building Certification Criteria was created in 2002 and expanded to schools in March, 2005. But the certificated schools just get the minimum score for certificate level 'good' about 65 points and there is no certificated school level 'very good'. The users of school stay in long time in the facility cause of the unique function of school. It means Indoor Environment Quality Criterion of the school is very important than any other criteria. Therefore, this study aims to analyze the indoor environment factor for the plan of the certificated school by green building rating systems. And this study also wants make the basement of a substantial technical application and development of the criteria in the plan for sustainable green school.

Green roof in Korea has been recognized as part of landscape area and local governments enacted municipal ordinance for supporting green roof thereby assisting part of expenses spent for green roof within a range of budget for buildings which are eligible for the green roof support of existing buildings. However, it is necessary to enforce a regulation of mandatory green roof for new buildings in order to expand green roof application and provide a variety of assistances such as subsidy payment, tax relief, and mitigation of floor area ratio-related regulation as done in other advanced nations. In particular, LEED(Leadership in Environmental and Energy Design) in the USA applies additional point directly for green roof in terms of the reduction in heat island effects. For example, the following items are beneficial to have additional points: habitat preservation or restoration, external space, rainwater management, reduction in outdoor water usage, minimum energy performance, and optimum energy performance. In addition, the BREEAM(Building Research Establishment Environmental Assessment Method) in the UK specifies green roof as one of assessment items to be complied in terms of diversity of species. As such, LEED and BREEAM reflect direct and indirect effects of green roof on assessment criteria, which suggest a direction to green building certification criteria in Korea where only additional points are given for green roof according to soil depth.

The present duration of 5 years in the Korea Green Building Certification(G-SEED) should be re-set taking into account with the needs for renewal of re-certification criteria. This study methods is to analyze the differences between the characteristics of the certification system of green building of domestic and foreign and to seek the improvement to derive the problem of detailed evaluation items of the examination. The purpose of this study is to identify some problems of re-certification criteria in the G-SEED System and to propose the renewal of certification system. Analysis of the rating criteria with a few re-certified examples of office buildings have been made. Some measures to improve the re-certification have been suggested as follows; (1) it is strongly suggested to establish re-certification rating systems that is not yet made, (2) the new criteria of re-certification bring into focus on whether buildings maintain the environmental performances of the initial status certified, and (3) thus the effective duration of re-certification needs to re-set flexibly in a way to confirm to the initial environmental performances and maintenance conditions certified.
