에너지성능지표(EPI)를 대상으로 한 개방형BIM기반 건축인허가 개선방향 제시
김인한,김민찬,최중식,Kim, Inhan,Kim, Minchan,Choi, Jungsik 한국건설관리학회 2015 한국건설관리학회 논문집 Vol.16 No.6
세계적으로 환경오염문제가 대두되면서 국내에서도 정부와 민간차원에서 친환경건축을 위한 노력이 활발히 진행 중이다. 하지만 건축물의 친환경 성능 및 친환경 관련 법규 및 기준 등에 대한 평가환경은 2차원기반의 수작업을 통한 평가로 진행되기 때문에 시간, 비용, 노동력 등이 많이 소요되며 평가의 정확성 및 효율성을 확보하기 어렵다. 따라서 본 논문에서는 개방형BIM기반으로 친환경건축 관련 인허가 업무의 개선을 목적으로 친환경건축 관련 인허가 조건 중 에너지성능지표 평가항목과 IFC포맷의 데이터와 연계를 통한 평가방안 모색하고 발생하는 문제점에 대한 대안을 제시하며 이를 반영한 평가프로그램의 활용으로 평가 프로세스를 제시함으로써 개방형BIM기반으로 에너지성능지표의 평가를 자동화하는 방안을 제시한다. 본 연구에서 제시된 방안을 친환경건축 관련 인허가 업무에 적용함으로써 업무절차의 간소화와 자동화를 통한 시간, 비용, 노동력의 절감을 기대할 수 있으며 설계변경 시 요구되는 절차가 단순화되어 업무의 생산성과 효율성이 향상되며 검토과정과 결과 값의 투명성과 검토의 정확성과 신뢰도를 확보 할 수 있을 것으로 기대한다.

Building Information Modeling (BIM) has been adopted in variety domain of construction industry. In this circumstances, interest of BIM model quality has been increased. In many countries, automated building code checking system by Industry Foundation Classes (IFC) has been developed and studied to use web based building permission systems. IFC is international standard of BIM format. However, the data structure of IFC does not include all of objects and properties about national building codes. In this paper, we developed the information specification between IFC data structure and national building code to increase interoperability. First, we drew the criteria from literature review to analyze the building code. And then, we analyzed building code and sorted objects and properties for automated building code checking. After that we made mapping table between the sorted data and IFC specification. Using the mapping table, we developed pre-specification about building codes information that does not exist in IFC specification. And the defined information can be used to develop the BIM modeling guide and national building permission system. The pre-specification support increasing the interoperability between user and automated building code checking system. Increasing thee interoperability makes improvement accuracy and reliability about result of automated building code checking.

개방형BIM기반 2D도면 자동 생성 프로그램 개발에 관한 연구

Especially for resolving BIM data compatibility issue, as one of recently raised BIM technology issues, has also been improved by using open BIM, representatively using IFC (Industry Foundation Classes) format. As shown in many case studies, usefulness of BIM technology is increasing day by day, and the IFC-based open BIM technology is essential in recent AEC projects where the productive collaboration is of importance. One of current problems in actual projects is that there is a conflict between conventional ways and newly developed BIM ways. Using both conventional and new technologies leads construction workers to having more work loads, consequently the efficiency and productivity of on-site workers have been decreased. Thus, it is strongly necessary to facilitate 3D BIM models to extract and generate 2D precision drawings in automation, especially using open BIM technologies. Some native BIM authoring tools have limitations in there automatic generation of 2D drawings, and there is no standardized mechanism to generate 2D drawings from heterogeneous applications. For this reason, this paper aims to develop an automated stand-alone program to generate 2D drawings in automation using IFC file, totally independent from various BIM authoring tools. By using the application described in this paper, any type of general drawings such as plan, section and elevation can be extracted without additional efforts. The development approach described in this paper, based on the open BIM technologies, has a strong impact to the current process especially in the perspective of enhancing productivity when we need to find out a trade-off in-between conventional and new approaches.

개방형BIM기반 건축 자동 법규검토를 위한 내·외부 공간 및 필로티 구조 자동 판별 알고리즘 개발
김인한(Inhan Kim),이아진(Ahjin Lee),이세진(Sejin Lee),김지영(Jiyoung Kim),최중식(Jungsik Choi) (사)한국CDE학회 2021 한국CDE학회 논문집 Vol.26 No.4
Various efforts are being made to commercialize BIM in Korea. Conformity assessment is used as a way to improve BIM data quality. When code checking, the use or the space is limited first. Thus, the importance of spatial classification increased, and the names of spaces were coded. However, there were cases where spaces with the same name were external and internal (e.g., Balcony), which could not be distinguished by spatial classification codes. Therefore, an automatic identification algorithm for internal and external space was developed and verified. Additionally, the piloti structure among the external spaces has clear conditions, so we developed the automatic identification algorithm for piloti structure using automatic identification algorithm for internal and external space. It is expected that it will be used when conducting research that automatically calculates areas.
