Building modelers need simulation tools capable of simultaneously considering building energy use, airflow and indoor air quality (IAQ) to design and evaluate the ability of buildings and their systems to meet today’s demanding energy efficiency and IAQ performance requirements. CONTAM is a widely-used multizone building airflow and contaminant transport simulation tool that requires indoor temperatures as input values. EnergyPlus is a prominent whole-building energy simulation program capable of performing heat transfer calculations that require interzone and infiltration airflows as input values. On their own, each tool is limited in its ability to account for thermal processes upon which building airflow may be significantly dependent and vice versa. This paper describes the initial phase of coupling of CONTAM with EnergyPlus to capture the interdependencies between airflow and heat transfer using co-simulation that allows for sharing of data between independently executing simulation tools. The coupling is accomplished based on the Functional Mock-up Interface (FMI) for Co-simulation specification that provides for integration between independently developed tools. A three-zone combined heat transfer/airflow analytical BESTEST case was simulated to verify the co-simulation is functioning as expected, and an investigation of a two-zone, natural ventilation case designed to challenge the coupled thermal/airflow solution methods was performed.

使用协同仿真将多区域气流和污染物传输软件CONTAM与EnergyPlus耦合。

建筑建模人员需要能够同时考虑建筑物能源使用，气流和室内空气质量（IAQ）的仿真工具，以设计和评估建筑物及其系统满足当今苛刻的能效和IAQ性能要求的能力。CONTAM是一种广泛使用的多区域建筑气流和污染物迁移模拟工具，需要将室内温度作为输入值。EnergyPlus是一个著名的整座建筑能源模拟程序，能够执行传热计算，需要区域间和入渗气流作为输入值。就其本身而言，每种工具在解释可能严重依赖建筑气流的热过程的能力方面受到限制，反之亦然。本文介绍了使用联合仿真将CONTAM与EnergyPlus耦合以捕获气流和传热之间的相互依赖性的初始阶段，该仿真允许在独立执行的仿真工具之间共享数据。耦合是基于用于共同仿真的功能模型接口（FMI）规范完成的，该规范提供了独立开发工具之间的集成。对三区域组合传热/气流分析最佳案例进行了仿真，以验证协同仿真是否按预期工作，并且对旨在挑战热/气流耦合方法的两区域自然通风案例进行了研究。耦合是基于用于共同仿真的功能模型接口（FMI）规范完成的，该规范提供了独立开发工具之间的集成。对三区域组合传热/气流分析最佳案例进行了仿真，以验证协同仿真是否按预期工作，并且对旨在挑战热/气流耦合方法的两区域自然通风案例进行了研究。耦合是基于用于共同仿真的功能模型接口（FMI）规范完成的，该规范提供了独立开发工具之间的集成。对三区域组合传热/气流分析最佳案例进行了仿真，以验证协同仿真是否按预期工作，并且对旨在挑战热/气流耦合方法的两区域自然通风案例进行了研究。
