Building energy analysis tools are available in many forms that provide the ability to address a broad spectrum of energy-related issues in various combinations. Often these tools operate in isolation from one another, making it difficult to evaluate the interactions between related phenomena and interacting systems, forcing oversimplified assumptions to be made about various phenomena that could otherwise be addressed directly with another tool. One example of such interdependence is the interaction between heat transfer, inter-zone airflow, and indoor contaminant transport. To better address these interdependencies, the National Institute of Standards and Technology has developed an updated version of the multi-zone airflow and contaminant transport modeling tool, CONTAM, along with a set of utilities to enable coupling of the full CONTAM model with the TRNSYS simulation tool in a more seamless manner and with additional capabilities that were previously not available. This article provides an overview of these new capabilities and applies them to simulating a medium-size office building. These simulations address the interaction between whole-building energy, airflow, and contaminant transport in evaluating various ventilation strategies including natural and demand-controlled ventilation. Practical application: CONTAM has been in practical use for many years allowing building designers, as well as indoor air quality (IAQ) and ventilation system analysts, to simulate the complex interactions between building physical layout and HVAC system configuration in determining building airflow and contaminant transport. It has been widely used to design and analyze smoke management systems and evaluate building performance in response to chemical, biological, and radiological events. While CONTAM has been used to address design and performance of buildings implementing energy conserving ventilation systems, e.g. natural and hybrid, this new coupled simulation capability will enable users to apply the tool to couple CONTAM with existing energy analysis software to address the interaction between IAQ considerations and energy conservation measures in building design and analysis. This article presents two practical case studies using the coupled modeling tool to evaluate IAQ performance of a CO2-based demand-controlled ventilation system under different levels of building envelope air tightness and the design and analysis of a natural ventilation system.

使用耦合能量、气流和 IAQ 软件 (TRNSYS/CONTAM) 评估建筑通风策略。

建筑能源分析工具有多种形式，能够以各种组合解决广泛的能源相关问题。这些工具通常彼此孤立运行，因此难以评估相关现象和相互作用系统之间的相互作用，迫使对各种现象做出过度简化的假设，否则这些现象可以直接用另一种工具解决。这种相互依赖的一个例子是热传递、区域间气流和室内污染物传输之间的相互作用。为了更好地解决这些相互依赖关系，美国国家标准与技术研究院开发了多区域气流和污染物传输建模工具 CONTAM 的更新版本，以及一组实用程序，以更无缝的方式将完整的 CONTAM 模型与 TRNSYS 仿真工具耦合，并具有以前不可用的附加功能。本文概述了这些新功能，并将其应用于模拟中型办公楼。这些模拟在评估各种通风策略（包括自然通风和需求控制通风）时解决了整个建筑能源、气流和污染物运输之间的相互作用。实际应用：CONTAM 多年来一直在实际应用中，允许建筑设计师以及室内空气质量 (IAQ) 和通风系统分析师模拟建筑物理布局和 HVAC 系统配置之间的复杂相互作用，以确定建筑气流和污染物输送. 它已被广泛用于设计和分析烟雾管理系统以及评估建筑性能以应对化学、生物和放射事件。虽然 CONTAM 已用于解决实施节能通风系统（例如自然和混合）的建筑物的设计和性能，但这种新的耦合模拟功能将使用户能够应用该工具将 CONTAM 与现有能源分析软件耦合，以解决 IAQ 考虑因素之间的相互作用建筑设计和分析中的节能措施。本文介绍了两个实际案例研究，使用耦合建模工具评估不同建筑围护结构气密性水平下基于 CO2 的需求控制通风系统的 IAQ 性能以及自然通风系统的设计和分析。
