随着建筑信息模型（BIM）工具的发展，管道单元的非几何属性，例如尺寸、流量和压力损失，可以直接导出。 BIM 已应用于众多建筑项目中。然而，使用工业基础等级 (IFC) 数据检查机械、电气和管道设计的性能数据并不清楚。在本研究中，介绍了根据 IFC2x3 规范的风管系统、元件、分配端口和用户定义的 IFC 属性集 (Pset) 的 IFC 定义。根据通风系统的设计准则，提取了摩擦损失、风道速度和扩压器颈部速度的三个校核规则。通过搜索风管单元与相关分配口之间的连接关系，提出了一种通风系统风管单元的排序算法。此外，关键路径是通过比较从不同散流器到 AHU 的路径长度来确定的。因此，提出了基于IFC的风管设计性能数据检查。还提供了一个案例研究。结果表明，关键路径上风管元件的性能数据满足设计标准，并计算了通风系统的总压损失。
With the development of Building information modelling (BIM) tools, the non-geometric attributes of duct elements, such as size, flow rate, and pressure loss, can be exported directly. BIM has been used in numerous building projects. However, there is no clarity in checking the performance data in mechanical, electrical, and plumbing design using the Industry Foundation Classes (IFC) data. In this study, the IFC definitions for duct system, element, distribution port, and user-defined IFC-property set (Pset) according to the IFC2x3 specification are introduced. Based on the design criteria for ventilation system, three checking rules for friction loss, duct velocity, and the diffuser’s neck velocity are extracted. A sorting algorithm for duct elements in the ventilation system is proposed by searching the connections between duct elements and the related distribution ports. Furthermore, the critical path is determined by comparing path lengths from different diffusers to the AHU. Therefore, the IFC-based performance data checking for the duct design is proposed. A case study is also presented. The results show that the performance data of the duct elements in the critical path meet the design criteria, and the total pressure loss of the ventilation system is calculated.
