基于IFC 与gbXML 标准的建筑信息模型与绿色建筑分析软件互操作性测试与评估

绿色建筑和建筑节能是建筑行业可持续发展的重要因素，然而建筑信息模型(BIM) 软件种类繁多、数据标准各异、软件之间的数据传递经常丢失信息。为解决不同软件之间的“信 息孤岛”问题和互操作性问题，分析了基于工业基础类标准(IFC)和gbXML 标准的绿色建筑模型 的结构框架，选取BIM 建模软件ArchiCAD 和绿色建筑性能分析软件Ecotec,对基于IFC 和 gbXML 标准的软件之间的互操作性进行了测试和评估，确定了建筑信息模型在交互过程中的问 题。针对相关问题本文提出了减少IFC 标准中的信息冗余、提高IFC 标准领域层对绿色建筑信 息的支持、提高资源层对相关信息定义的针对性等建议。

IFC and gbXML Based Test and Evaluation for the Interoperability BetweenBIM Modeling Software and Green Building Performance Analysis Software

Green building and building energy conservation are important factors in the sustainable development of the construction industry. However, BIM (building information modeling) has a wide range of software and various data standards, and loss of information is frequent during the data transfer. Thus solving the “information island” problem and the interoperability issues between different software is the key for BIM application. This paper first analyzes the green building framework based on IFC (industrial foundation classes) and gbXML standards, and chooses BIM modeling software ArchiCAD and green building performance analysis software Ecotec to test and evaluate the interoperability, so as to identify the problems of BIM data standards and BIM tools in the process of BIM data transfer. The paper provides specific improvement methods and suggestions to solve the problems, including reducing the information redundancy for IFC formats, increasing the support to green building area in the IFC standard, and improving the accuracy for the definition of green building information in the IFC resource layer.
