This paper presents an algorithm to translate building topology in an object-oriented architectural building model (Building Information modeling, BIM) into an object-oriented physical-based energy performance simulation by using an object-oriented programming approach. Our algorithm demonstrates efficient mapping of building components in a BIM model into space boundary conditions in an object-oriented physical modeling (OOPM)-based building energy model, and the translation of building topology into space boundary conditions to create an OOPM model. The implemented command, TranslatingBuildingTopology, using an object-oriented programming approach, enables graphical representation of the building topology of BIM models and the automatic generation of space boundaries information for OOPM models. The algorithm and its implementation allow coherent object-mapping from BIM to OOPM and facilitate the definition of space boundaries information during model translation for building thermal simulation. In order to demonstrate our algorithm and its implementation, we conducted experiments with three test cases using the BESTEST 600 model. Our experiments show that our algorithm and its implementation enable building topology information to be automatically translated into space boundary information, and facilitates the reuse of BIM data into building thermal simulations without additional export or import processes.

This study presents a Building Information modeling (BIM) to Building Energy modeling (BEM) translation framework (BIM2BEM) through the integration of BIM with object-oriented physical modeling (OOPM) for building thermal simulation to support sustainable building design. A Model View Definition (MVD) is used as a data modeling methodology to assist BIM2BEM, and an application of BIM2BEM is demonstrated by visualizing energy performance in BIM. The framework of BIM2BEM is made of a system interface between BIM and OOPM-based BEM (ModelicaBEM). The interface consists of the following two major phases: (1) pre-processing BIM models to add required thermal parameters into BIM and generate the building topology, and (2) translating BIM to ModelicaBEM automatically and running the thermal simulation. Finally, a case study was conducted to demonstrate and validate the simulation results. The MVD enables efficient model translation consisting of a process model and a class diagram. The process model demonstrates the object-mapping process from BIM to ModelicaBEM and facilitates the definition of required information during the model translation process. The class diagram represents the object information and object relationships for producing the software tool for automatic model translation. In order to demonstrate and validate the approach, simulation result comparisons have been conducted for three test cases, each having two models: (1) the BIM-based Modelica model (ModelicaBEM) generated using the framework, and (2) the model manually created using Lawrence Berkeley National Laboratory's Modelica Buildings library. The results show that the framework: (1) enables BIM models to be translated into ModelicaBEM models, (2) enables system interface development based on the MVD for thermal simulation, and (3) facilitates the reuse of the original BIM data for building energy simulation without an import/export process. The visualization application enables visualizing build

OOPM: An object-oriented multimodeling and simulation application framework

引用

SIMULATION 1998年第6期70卷 379-395页

作者： Cubert, RM Fishwick, PA Univ Florida Dept Comp & Informat Sci & Engn Gainesville FL 32611 USA

OOPM, or object-oriented physical Multi-modeling, is an application framework for modeling and simulation under development at the University of Florida. It extends object-oriented program design with visualization and a definition of system modeling that reinforces the relationship model to program. Model authors interact with OOPM via graphical user interface, which captures model design, translates models to simulation programs, controls model execution and provides output visualization. Distributed Model Repository facilitates collaborative and distributed model definitions and model reuse. Translator converts model definition to a simulation program in C++, then compiles and links this simulation program, adding run-time support and creating an executable which runs under control of Scenario to provide output visualization using Virtual Reality modeling Language. A variety of model types may be freely combined through heterogeneous multimodeling, which is the basis fro geometry and dynamic behavior models.
