다양한 이해관계자들이 참여하게 되는 현재 건설산업에서 표준 포맷을 사용한 Building Information Model (BIM) 데이터 교환은 건물 전 생애주기에 걸쳐 관련 실무자들에게 보다 효율적인 업무 환경을 제공해 줄 수 있다. 하지만, 설계 프로그램에서 Industry Foundation Class (IFC) 포맷의 파일을 사용하여 건축물 에너지 분석으로 데이터 교환 시 BIM 정보에서 추출된 자재 정보를 에너지 분석 도구에서 직접 사용할 수 없어 추가적인 데이터 입력 작업이 필요한 실정이다. 이에 따라 본 연구에서는 건축물 자재에 관련하여 에너지 분석 엔진인 DOE-2 의 기본 라이브러리에서 사용하고 있는 자재 라이브러리와 매칭될 수 있도록. IFC 파일에서 추출된 건축물 자재 표기명을 에너지 분석 프로그램의 자재 라이브러리 표기명과 자동으로 매칭 시키는 온톨로지를 구축하였다. 본 연구는 에너지 분석 시 분석 과정의 효율성 및 분석 결과에 대한 객관적인 신뢰도를 향상시키고, 건설사업에서 온톨로지 활용에 대한 개념연구로서 그 의의가 있다고 할 수 있다.

Automated rebar fabrication, which requires effective information exchange between model designers and fabricators, has brought the integration and interoperability of data from different sources to the notice of both academics and industry practitioners. Industry Foundation Classes (IFC) was one of the most commonly used data formats to represent the semantic information of prefabricated components in buildings, whereas the data format utilized by rebar fabrication machine is BundesVereinigung der Bausoftware (BVBS), which is a numerical data structure exchanging reinforcement information through ASCII encoded files. Seamless transformation between IFC and BVBS empowers the automated rebar fabrication and improve the construction productivity. In order to improve data interoperability between IFC and BVBS, this study presents an IFC extension based on the attributes required by automated rebar fabrication machines with the help of Information Delivery Manual (IDM) and Model View Definition (MVD). IDM is applied to describe and display the information needed for the design, construction and operation of projects, whereas MVD is a subset of IFC schema used to describe the automated rebar fabrication workflow. Firstly, with a rich pool of vocabularies practitioners, OmniClass is used in information exchange between IFC and BVBS, providing a hierarchy classification structure for reinforcing elements. Then, using International Framework for Dictionaries (IFD), the usage of each attribute is defined in a more consistent manner to assist the data mapping process. Besides, in order to address missing information within automated fabrication process, a schematic data mapping diagram has been made to deliver IFC information from BIM models to BVBS format for better data interoperability among different software agents. A case study based on the data mapping will be presented to demonstrate the proposed IFC extension and how it could assist/facilitate the information management.
