This paper demonstrates our researched methodology to translate a building information model into an object-oriented physical modeling(OOPM)-based building energy model (BEM) for building energy simulation. The proposed approach (BIMOOPMBEM) has been investigated by adopting a data modeling method to support seamless model translations including building geometry, materials, and building topology. The data modeling enables us to create a model view definition (MVD) containing a process model and a class diagram. The process model explains object-mapping between a BIM and an OOPM-based BEM (OOPMBEM) and enables the definition of required information during model translations. The class diagram represents the required information and object relationships to create a exchange model view to create BIM-based OOPMBEMs. The implementation of the wrapper and interface class in the exchange model view using Modelica and object-oriented programming language enables the developed system interface to automatically create BIM-based OOPMBEMs. In order to demonstrate and validate our approach, we conducted simulation result comparisons through a test case using (1) automatically created a BIM-based OOPMBEM from the system interface and (2) OOPMBEM manually created using adopted LBNL Modelica Buildings Library. Our implementation presented that BIMOOPMBEM enables a BIM to be translated into an OOPMBEM by automatically creating a BIM-based OOPMBEM and the directly reuse of original BIM data into building thermal simulation.

사용자의 공간 요구사항 중심의 평면계획에 대한 수요가 증가함에 따라 소형 주택시장이 지속적으로 성장하고 있다. 하지만 건축주는 공간 구성이나 비용 견적과 같은 근거를 기반으로 평면요구사항을 개진하는데 매우 제한적인 수단을 활용하고 있어 건축가와 같은 전문가들과의 소통에 많은 어려움을 겪고 있다. 본 연구의 목적은 스케치 정보 기반의 공간 요구사항을 BIM 모델의 3D 건물구성요소로 자동 변환하여 사용자의 공간에 대한 이해를 돕고, 초기 설계단계에서 예산 산정을 지원하기 위한 건물성능분석 정보를 제공할 수 있는 프레임워크 개발에 있다. 본 연구의 방법론은 프로세스 모델 개발, 프레임워크 구현 및 검증단계로 구성되었다. 프로세스 모델 개발은 프레임워크의 데이터 흐름을 묘사하고 프레임워크에 필요한 기능을 정의하는 단계이며, 프레임워크 구현은 프로세스 모델을 기반으로 시스템 인터페이스와 사용자 인터페이스를 개발하고, 이종 시스템 간의 연동 방식을 정의하는 단계이다. 검증단계는 개발된 프레임워크가 스케치 정보로 표현된 공간 요구사항을 BIM 모델의 벽, 바닥, 지붕과 같은 건물 구성요소 객체들로 자동 변환할 수 있는가를 검증하였다. 또한 프레임워크가 BIM 모델을 기반으로 재료 및 에너지 비용을 자동으로 산출할 수 있는가를 검증하였다. 프레임워크를 통해 사용자는 스케치 정보를 기반으로 3D 건물 구성요소를 효율적으로 생성할 수 있으며, 생성된 BIM 모델을 통해 공간을 이해하고 건물성능분석 정보를 제공받을 수 있다. The market for compact houses is growing due to the demand for floor plans prioritizing user needs. However, clients often have difficulty communicating their spatial requirements to professionals including architects because they lack the means to provide evidence, such as spatial configurations or cost estimates. This research aims to create a framework that can translate sketched data-driven spatial requirements into 3D building components in BIM models to facilitate spatial understanding and provide building performance analysis to aid in budgeting in the early design phase. The research process includes developing a process model, implementing, and validating the framework. The process model describes the data flow within the framework and identifies the required functionality. Implementation involves creating systems and user interfaces to integrate various systems. The validation verifies that the framework can automatically convert sketched space requirements into walls, floors, and roofs in a BIM model. The framework can also automatically calculate material and energy costs based on the BIM model. The developed frame enables clients to efficiently create 3D building components based on the sketched data and facilitates users to understand the space and analyze the building performance through the created BIM models.

최근 건설프로젝트는 기존의 노동집약적 현장생산 방식이 아닌, 공장 생산 기반의 현장 조립 방식인 모듈러 건축물에 주목하고 있다. 모듈러 건축 공법은 기존 방식에 비해 공기 단축효과가 높고, 해체 및 재사용이 용이해 임시 주거시설을 중심으로 적용되고 있다. 그러나 모듈러 공법 실현을 위한 초기 투자비용에 대한 부담으로 인해 국내의 모듈러 건축시장은 아직 활성화되지 못하고 있다. 이에 본 연구에서는 모듈러 건축물이 가지고 있는 경제적 부담에 대한 대안으로서 시장의 수요에 따라 이동 가능한 모듈러 건축 방식에 대하여, 기존의 건축 방식과의 생애주기비용 비교를 통해 경제적 효과를 분석하고자 한다. 본 연구에서 분석의 대상으로 삼은 RC 공법과 모듈러 공법의 이동형 모델의 경제성 평가 결과, 단기적인 측면에서는 RC공법이 빠른 수익률을 달성하였지만 건물의 전 생애주기 측면에서는 이동 가능한 모듈러 건축 방식의 경제성이 보다 큰 것으로 나타났다. Construction industry pays attention to modular construction recently which based on factory production not on labor intensive site production. Since modular construction has high time shortening effect and easiness of demolition and recycling, it has been applied to the temporary residential building. Domestic modular construction market are not activated yet, however, due to the high initial cost to realize modular construction. This study proposes demand-sensitized movable modular building in order to reduce the financial burden. The study compares between RC method building and Modular building which moves building when the demand falls off from Life-Cycle Cost's viewpoint. As a result of the economical evaluation, RC method achieved profits faster than Modular model, but Modular model's gross earnings during the life-cycle are much bigger than RC method. In other words, the result means that the market-sensitized movement of the modular building would be an economci choice in Life-Cycle Costing aspect.

공병찬(Kong, ByungChan),정운성(Jeong, WoonSeong) 대한건축학회 2023 대한건축학회 학술발표대회 논문집 Vol.43 No.2

This research aims to develop a framework to efficiently create a Object-Oriented Physical Model(OOPM) based on Building Information Modeling using Functional Mock-up Interface, which facilitates the integration of simulation models created from diverse simulation tools. The framework development consists of two phases: the process model development and the framework implementation. The prototype retrieves the design information for energy simulation from the Building Information Model to create a Functional Mock-up Unit(FMU). The FMU is then integrated with the pre-defined OOPM model in the co-simulation environment to create the OOPM analytical model. The simulation results of the OOPM analytical model confirmed the accurate translation of thermal properties and material information for walls.

Recently, there have been a growing number of cases using precast concrete construction methods to efficiently carry out construction projects. In order to efficiently carry out PC construction, it is necessary to establish a production plan of PC components that effectively reflect various design alternatives during the initial design stage. Because the production plan of PC components is based on productivity of PC members, the use of PC production simulations that can effectively predict productivity for design alternatives is necessary. Therefore, this paper propose a method to efficiently generate design alternatives which is necessary to perform to production simulations using parametric modeling techniques and BIM.

This paper presents the development of the framework to create Virtual Reality (VR) interactive model using BIM and deep learning technique. The goal is to support the non-expert’s decision-making process required in the footprint development, and to facilitate efficient communication between experts and non-experts such as architects and owners. The proposed framework consists of following steps: development of a process model, framework implementation, and validation. The findings in the validation step present that the framework is effective in the qualitative spatial evaluation such as spatial modification using the furniture layout, and efficient in the quantitative spatial evaluation through the estimation of the direct material cost and the annual electric and gas energy consumption.

Recently, the fourth industrial revolution has a great influence on the development of many industries as well as the construction industry. Various technologies related to the industrial revolution 4.0, such as AI and big data, have gained much attention. However, little has been known about the importance and preparedness of stakeholders of the construction industry in Korea for the industry 4.0 technologies so far. This study revealed how the stakeholders perceive and prepare for industry 4.0 using a survey. In addition, collaboration potential score for each technology was calculated to find technologies with high potential for collaboration. Result is that the importance of the technologies was evaluated high in overall, but the preparedness and implementation in university education or business was evaluated low. Technologies with high potential for industry-university collaboration are AI/big data and 3D printing/3D scanning. This study can contribute to the training of industry 4.0 experts and improving preparedness, which would enable the innovation and application of industry 4.0 technologies in the construction industry.
