创建建筑性能仿真模型非常耗时，需要大量专业知识和建筑专业知识。构建模型所需的资源总投资在很大程度上取决于考虑中的建筑的大小和复杂性，但一般来说，这项工作可以被视为四个步骤:收集必要的建筑信息，将这些信息转换为模拟程序所需的格式，解决出现的任何问题，并模拟建筑。如果建模者需要为分析过程使用多个模拟程序，那么很可能每个程序都必须重复大部分过程。 即使不需要额外的数据（不需要第一步），建模人员也可能需要将这些信息转换为每个模拟程序的不同形式，故障排除和模拟步骤需要了解正在使用的模拟程序。本文描述了一种“单一模型”方法，其中使用更复杂的EnergyPlus能量模型来生成不太复杂的CONTAM气流模型。这减少了在单个建筑上执行这两种分析所需的总体工作量。生成的气流模型功能齐全，适合用于参数模拟研究，但必要时，其详细程度不如目的- 建造的模型可能是。该过程使用一个基本能量模型，该模型由开源的OpenStudio能量建模工具集构建，然后使用OpenStudio软件开发工具包转换为简化的气流模型。本文介绍了一个污染物传输应用实例，即针对化学/生物极端事件的建筑物安全量化，并讨论了这种方法的优点和局限性，以及未来可能的应用。引用:ASHRAE论文CD:2014 ASHRAE冬季会议，纽约

The creation of building performance simulation models is time consuming and requires a great deal of expertise and building-specific knowledge. The total investment of resources required to construct a model strongly depends upon the size and complexity of the building under consideration, but in general the effort may be thought of as a four-step process: gather the necessary building information, convert this information into the format required by the simulation program, troubleshoot any issues that arise, and simulate the building. If the modeler needs to use more than one simulation program for the analysis process, then it is likely that much of the process must be repeated for each program. Even if no additional data are required (removing the need for the first step), the modeler will likely need to translate this information into a different form for each simulation program and the troubleshooting and simulation steps will require knowledge of the simulation program in use. This paper describes a "single model" approach, in which a more complex EnergyPlus energy model is used to generate a less complex CONTAM airflow model. This reduces the overall effort required to perform both analyses on a single building. The resulting airflow models are fully-functional and are suited for use in parametric simulation studies but by necessity are not as detailed as purpose-built models might be. The procedure uses a base energy model that is constructed with the open-source OpenStudio energy modeling toolset and then translated into a simplified airflow model using the OpenStudio software development kit. An example contaminant transport application, quantification of building security against chemical/biological extreme events, is presented and the advantages and limitations of this approach are discussed, along with possible future applications.
