  • Over the world, social demands and concerns of energy and resource depletions and environmental conservation have resulted in many researches and applications on sustainable development and construction. In order to support these demands and concerns, international green building certification systems such as LEED(Leadership in Energy and Environmental Design) and BREEAM(Building Research Establishment Environmental Assessment Method) were developed. In Korea, the green building certification system was introduced in 2000 and widely applied to all types of new buildings in order to induce the diffusion of sustainable buildings on May, 2010. This paper investigates the importance of assessment criteria on multi-unit apartment projects among certification rating systems using the AHP(Analytic Hierarchy Process) method and suggests a new direction on certification assessment standards. For applying the AHP method, the survey of staffs in green building certification consulting companies and architectural design companies was conducted via e-mail. As a result, criteria like energy, indoor environment, land use, pollution control, and ecological environment among 9 main ones turned out important on assessing green building certification at multi-unit apartment projects, while criteria like water resource, transportation, maintenance management, and material and resource did relatively unimportant.

  • The concern of green building has been increased with an environmental problem or a rising oil price by industrialization. Therefore offices, schools and some buildings are expected to acquire the green building certification increasingly, but the information such as a process of green building certification, the state of certificated buildings, a score as specific clauses on green building certification is to seek. For not only school facilities make an effect to an student's learning achievement, but is the place where adolescents in a period of growth almost spend their life, eco-friendly school facilities is absolutely required. For this reason, systematizing the information related with the green building certification is to be needed in school field as well Therefore the effort to systematize certification management of eco-friendly school and provide information of certificated building, certification application procedure and sources related with certification for convenience is needed. Also reference material to decrease an inefficient time and expenses and to systematize certification evaluation is be able to beneficial. On the study, for such as the purpose above-mentioned, as the appraisal standard with 12 selected schools randomly is arranged. Based on the assessed scores table, features or something in common as a cause of the score change between preliminary and main certification is to be classified and anaylized.

  • 국내 건설산업은 에너지와 자원의 사용 및 오염물질 배출과 같은 환경 부담을 줄이고 쾌적한 환경을 조성하기 위한 목적으로 건축물의 환경성을 평가하는 녹색건축 인증제도를 시행하고 있다. 하지만 인증획득 절차의 시간이 오래 걸리고 과정이 복잡하며 인증 항목별로 자재의 경제성을 고려할 수 없는 점으로 인해 실무에서는 인증에 어려움을 겪는 문제점이 있다. 따라서 본 연구에서는 녹색건축인증의 문제점을 해결하기 위해 녹색건축 인증제도 인증 항목 중 실내공기 오염물질 저방출 제품의 적용을 그 대상으로 하고 생애주기비용 개념을 고려하여 자재 데이터베이스를 구축하였으며 경제성 평가의 최적화 기법으로는 유전 알고리즘을 활용하여 최적의 자재를 선정할 수 있는 경제성 평가모델을 개발하였다. 이를 실제 비주거용 건축물 사례에 적용하여 기존 비용과 비교한 결과 평균 74.5 %의 비용 절감률을 나타내어 본 모델을 녹색건축인증에서 경제적 효율성이 있는 도구로써 활용 가능할 것으로 판단된다.

  • Environmental problems caused by rapid industrialization and environmental issues have emerged worldwide. The Green Building Certification Policy has been introduced. The purpose of this study is to evaluate the environment-friendly planning factors in Environment-friendly Housing Certification. Six multi-family housing in Environment-friendly Housing Certification have been analyzed. The findings of this study are as follows. While outdoor planning factor is focused on building arrangement and ecological environment, its application in building material and environment plan is inadequate. In ecological environment, various green planting systems such as green zone and plant inhabitation area are utilized.

  • The awareness of ecological friendliness has been emerging in the recent years, and the application to housing is quite notable. The purpose of this study is to evaluate environment-friendly planning factor in Environment-friendly Housing Certification. For this purpose, this study has analyzed 5 multi-family housing in Environment-friendly Housing Certification. The findings of this study are as follows: The application of environment-friendly planning factor in interior space are limited. Most of plans are located in south. The variability of floor plan is not applied but the built-in storage is well-applied. Environment-friendly finishing material and the garden-style balconies was applied in a passive way. This analysis showed current status of planning factor of unit apartment in Environment-friendly Housing Certification and proved basic information for future direction.

  • Purpose: The green building certification system in Korea was introduced in 2002 and developed as an improvement version of the G-SEED(Green Standard for Energy and Environmental Design) system in 2013. This study conducts surveys targeting architectural designers and users on significance of certification assessment criteria for apartment buildings on the G-SEED system and examines the differential views between the two groups on assessment criteria. Method: First, The AHP(Analytic Hierarchy Process) method was used to find importance of assessment criteria and then the importances were compared with weighted points on the certification standard. Second, the t-test was used to investigate differential views between designer and user groups on certification assessment criteria based on drawn importances. Result: (1) While designer group considered land use and transportation, energy and environmental pollution, and water circulation management as more important, user group did material and resource, maintenance management, ecological environment, and indoor environment as more important. (2) Based on t-test results, sustainable energy, water circulation system, site management, habitat, acoustical environment, and light environment were found to be different on importance between the two groups.

  • 현재의 친환경인증평가 과정은 전통적 수작업에 의한 평가방법으로 많은 시간과 인력을 필요로 하며 평가자의 경력과 주관에 따라 평가 결과에 영향을 끼치게 된다. 이러한 문제점의 해결방안중의 하나로 평가과정을 시스템화하여 평가에 대한 객관성을 부여함으로써 평가결과에 대한 신뢰성을 높일 수 있으며 처리과정의 오류방지나 시간 절약등의 효과를 높일 수 있는 방안이 필요하게 되었다. 따라서 현재 건축설계에 도입되고 있는 BIM 방식의 설계정보를 이용하여 자동화된 친환경인증평가 시스템의 구축 가능성을 타진하고 가능한 분야에 대한 평가시스템을 구축함으로써 친환경인증평가 시스템화의 기반을 마련하고자 하였다.
