| 摘要该文提出一种基于建筑信息模型（building information modeling，BIM）数据标准工业基础类（industry foundation classes，IFC）的绿色性能分析数据转换与共享方法。首先，通过分析IFC标准与常用绿色性能分析数据格式gbXML的结构及其对绿色性能信息的描述机制，建立了二者主要信息元素之间的映射关系；并提出了IFC向gbXML的自动转换方法，实现了绿色性能分析数据的转换与共享。最后，将上述方法在实际案例中进行了测试验证。结果表明：该方法实现了IFC向gbXML的自动转换，支持不同参与方与应用之间绿色性能分析数据的交换与共享，有效降低了信息重复建模成本，提高了效率。 | |||

| Abstract：An IFC-based data conversion algorithm was developed to automatically convert BIM model data to gbXML format for building performance information sharing. The IFC and gbXML data were mapped and related in an automatic conversion algorithm. The algorithm was validated with different project data sets to show that the algorithm allows performance information sharing among different stakeholders by eliminating reworking of the data models and improving efficiency. | |||
