1.1 本指南为室内空气质量（IAQ）模型的评估提供了定量和定性工具。这些工具包括评估整体模型性能以及识别特定缺陷领域的方法。还提供了选择模型评估数据集以及应用和解释评估工具的指导。该指南的重点是最终结果（即模型预测的室内浓度的准确性），而不是操作细节，如模型实施的难易程度或进行模型计算所需的时间。 1.2 尽管室内空气质量模型已经使用了一段时间，但技术文献中很少有关于评估此类模型的指导。本指南中的评估原则和工具来自过去与室外空气质量或气象模型相关的工作，这些模型的目标与室内空气质量模型相似，并有评估文献的历史 ( 1. ) . 2. 在使用这些工具评估室内空气质量模型方面存在一些有限的经验。 1.3 以国际单位制表示的值应被视为标准值。本标准不包括其他计量单位。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 =====意义和用途====== 4.1 使用本指南中描述的工具，寻求应用室内空气质量模型的个人应该能够( 1. )评估模型在特定情况下的性能，或( 2. )认识或评估其优势和局限性。 4.2 本指南也可用于识别需要进一步开发或改进的模型缺陷的特定领域。

1.1 This guide provides quantitative and qualitative tools for evaluation of indoor air quality (IAQ) models. These tools include methods for assessing overall model performance as well as identifying specific areas of deficiency. Guidance is also provided in choosing data sets for model evaluation and in applying and interpreting the evaluation tools. The focus of the guide is on end results (that is, the accuracy of indoor concentrations predicted by a model), rather than operational details such as the ease of model implementation or the time required for model calculations to be performed. 1.2 Although IAQ models have been used for some time, there is little guidance in the technical literature on the evaluation of such models. Evaluation principles and tools in this guide are drawn from past efforts related to outdoor air quality or meteorological models, which have objectives similar to those for IAQ models and a history of evaluation literature ( 1 ) . 2 Some limited experience exists in the use of these tools for evaluation of IAQ models. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 Using the tools described in this guide, an individual seeking to apply an IAQ model should be able to ( 1 ) assess the performance of the model for a specific situation or ( 2 ) recognize or assess its advantages and limitations. 4.2 This guide can also be used for identifying specific areas of model deficiency that require further development or refinement.
