친환경 저에너지 중점의 건축설계의 중요성이 점점 커져가고 있다. 또 한편으로는 좀 더 미시적인 관점의 에너지 절약 설계 기법이 요구되고 있다. 이러한 분위기 속에서 에너지 시뮬레이션의 필요성이 점차 증가하고 있으며, 특히 BIM 기반의 에너지 시뮬레이션은 높은 효율성으로 인해 주목받고 있다. 하지만 BIM의 데이터는 아직까지는 미시적인 에너지와 관련된 파라메터가 적용되어 있지 않다. 따라서 본 연구는 조도 센서에 의한 조명 제어 시뮬레이션을 통해 센서 조명 파라메터의 생성 필요성에 대해서 연구하고자 한다. 연구는 BIM을 통해 생성된 데이터를 바탕으로 조도 센서를 설치하고 조도 시뮬레이션을 통해 센서등의 스케줄 데이터를 생성하였다. 그리고 이렇게 생성된 스케줄 데이터를 바탕으로 에너지 시뮬레이션을 실시하여 소비전력의 감소율을 확인하였다. 연구에 따르면 조명에 따른 열부하량과 소비전력량이 각각 20%이상 감소하는 것으로 나타났다. 따라서 센서 조명 파라메터는 미시적인 에너지 절약 설계를 위해서 BIM 데이터 내에 생성될 필요가 있다고 판단된다. 본 연구는 센서 조명 파라메터의 생성에 국한된 것이 아니라, 이와 같이 미시적인 변인들을 검토하고 BIM 데이터 내에 적용할 필요가 있음을 밝히기 위해 수행되었다.

설계단계에서 작성된 BIM모델은 후속 단계 전환을 통한 사전검토 및 공정관리 등에 활용될 수 있다. 그러나 실제 BIM적용 사례들의 경우 설계단계와 시공단계의 활용 목적성 등의 차이로 인해 설계단계의 모델의 활용이 아닌 시공단계에 적합한 새로운 모델을 작성하는 등 추가 작업이 요구된다. 따라서 본 연구에서는 시공단계에서 재작성 없이 설계단계 BIM모델의 재활용 방안으로 객체 분할을 제안하며, 이를 위해 객체의 기본요소인 정점 데이터를 기반으로 분할 면을 생성하여 객체 분할에 활용하는 방법론을 제시한다. 또한 실제 BIM모델에 적용 및 분할 객체의 4D CAD 시스템 연동과 기존 분할 방법과의 비교를 통해 활용성을 검증한다.

About 30% of the total annual energy consumption on the earth is used in the architectural activities, including construction, maintenance management, and demonstration of a building. Also, 40% of the natural resource consumption, 50% of $CO_2$ emissions, and 20%~50% of industrial waste emissions are produced from a building. Unfortunately, the percentage of its energy consumption is staidly increasing year by year, about 8% every year, and it recently causes a sustainable architectural concept to come to the fore globally. Indeed, the importance of the sustainable architecture is increasingly becoming a worldwide trend. BIM(Building Information Modeling) is considered a new paradigm and a powerful method in building design, construction and maintenance. BIM has characteristics similar to a building's systems. All of the components in a model have a parametric relationship to each other. Understanding and capitalizing on these interrelationships typically takes numerous iterations that span multiple projects. Optimizing the integrated strategies and technologies for a high-performance, sustainable design requires a continual look at understanding how they work together to deliver the best potential. Throughout all of these concepts, we are going to be using a variety of tools that revolve around a BIM model. Some of the tools will require a heavier use of BIM than others, but all of them will utilize the model geometry you've created as part of your design. This study presents importance and validity of energy performance analyzation in the pre-design phase for the sustainable architecture with the support of Building Information Modeling (BIM) technology.

Reinforcing bars, a major component of the pre-fab structure, adheres to the existing on-site assembly method and attempts to develop and commercialize the technology of the pre-assembly method, but the effect is insignificant. Welded Wire / Bar Mat (WBM) has various advantages such as commercialization of rebar through machine manufacturing to improve workability, but it is different from the existing design and the construction method is different from the previous one. Therefore, to maximize the advantages of WBM and improve productivity, manufacturing, transportation, and construction from the design stage should be considered based on BIM from the initial design stage. In this paper, the concept of the design support system for the WBM was established based on the use of BIM in concrete reinforcement and the preliminary research on the WBM. WBM conversion design was performed for the existing prefabricated members, and based on this, the exchange format and system of the master prefabricated model with the WBM design data were set up. As a result of the pilot test, it was found that the traditional reinforcing bar information extracted from the master prefab model has transmitted 100% accurately. As for the WBM information, 100% of the information on the straight reinforcement was transmitted and represented, and the information on the bent reinforcement was found to have a 90% recall in the master BIM tool.

Dweller's safety is one of the most important factors for the evaluation of building performance. The process of conventional safety design which is normally performed by the codes and designer's experiences is not enough to check the whole possibilities of unexpected accidents in the built environment. It means that the dwellers might be always exposed by the dangerous situation which should have been removed in the architectural design process. In order to solve this problem, this study intends to introduce a rule-based performance evaluation technology based on BIM(Building Information Modeling). The proposed technology focuses on the real time evaluation of dweller's safety in the ordinary life in the designed building alternatives and uses a commercial BIM tool as a design and evaluation platform.

BIM(Building Information Modeling) is considered a new paradigm and a powerful method in building design, construction and maintenance. However, it is still hard to implement environmental performance analysis using BIM in design stages. This study aims to reveal practical problems and evaluate interoperability between building design information and performance analysis with case studies. Three case studies are performed using two environmental analysis programs (IES/VE, EnergyPlus) and BIM-based architectural design programs (Revit, GoogleSketchUp) in this paper.

The application of the BIM for the KEPCO' new headquarters in Naju involved alternative approaches and accompanied many trials-and-errors as the project adopted new targets and purposes that were not used in Korea before. In particular, for a large BIM-based project, clearly defining the BIM-including the objective, scope and the outcome-is critical for a project owner. For a successful implementation, project owners should improve the utilization of the BIM. Against this background, this research examines the case of the BIM application for the KEPCO' new headquarters in Naju, identifies its effects and problems, and proposes how to improve application of the BIM for public projects. The improvement in the BIM application can be divided into several stages: project order, design development, construction, and post-construction maintenance. In the initial stage, it is important to fully discuss the project planning among participants, and clarify the goal, scope, expected outcomes and role of the BIM. In the design stage, the level of detail (LOD) for the 3D model should be defined in consideration of information use in the stages of estimation and construction. In the construction stage, the scope of project that is managed based on the processing and use of the BIM data should be clearly given and understood. After construction is complete, measures should be sought to use the BIM for maintenance, and corresponding requirements and outcomes should be provided. The analysis is expected to provide basic data for successful implementation of BIM-based public projects, by assisting project owners and involved parties in enhancing work in different stages of a project.

BIM(Building Information Modeling)은 원칙적으로 건설 전 생애주기에 걸쳐 활용되어야 그 효과를 극대화 할 수 있으나, 아직은 계획 및 설계단계에 비하여 공사단계에서는 그 활용도가 상당히 낮은 수준이었다. 최근 대형 국책사업이 발주, 시공되면서 효율적인 공사관리를 위한 방법으로 3D 성과품 검토나 4D 공정관리 등 BIM기법 중 일부가 도입되고 있다. 본 연구에서는 토목시설물의 공사단계에서 BIM 활용방안에 대하여 제시하였다. 토목공사의 종류별, 관리 분야별 BIM 활용방안에 대하여 논의하고, 서울 지하철 919공구에 실제로 적용하여 그 효용성에 대하여 분석하였다. 특히, 현장에 구축된 BIM 기반의 웹 공사관리 시스템은 공사중, 현장과 본사를 비롯해 발주처와 감리단 등 다수의 공사 주체들이 BIM을 보다 효과적으로 사용하도록 함으로써, BIM의 공사단계 활용성을 높일 뿐만 아니라 유지관리 단계까지 확장하여 이용될 수 있다.

It seems obvious that the spatial information of existing architectural heritage will be re-structured utilizing BIM technology. In the future to be able to implement such task, a new system of classification of spatial information, which fit to the structural nature of architectural heritage is necessary. This paper intend to suggest the conceptual model that can be the base of establishing new classification system for architectural heritage. For this study we reviewed researches related to classification system of architectural heritage (CS-AH) and BIM based architectural heritage (BIM-AH), first. As a result, we found that CS-AH is focused on building elevation and type, and BIM-AH is biased on the Library and Parametric Modeling. Second, we figured out a relationship between the CS-AH and BIM-AH. From this analysis, we found that BIM-AH is biased on Library and Parametric since the building elevation and type was focused on CS-AH. This review suggests a potential of the 3D CS-AH to expand the range of research for BIM-AH. At last, we suggest the three concept of classification are: 1)horizontality-accumulation relationship, 2)structure-infill relationship, 3)segment-member relationship. These three concept, together as one system of classification, could provide useful framework of new classification system of spatial information for architectural heritage.
