住宅建筑物的渗透和通风率随建筑类型、天气条件和织物开口的操作而变化。生成良好的通风估计对于建模、仿真和性能评估非常重要，因为它对能耗有重大影响。可以采用物理试验来估计渗漏，但在大多数情况下，这是繁琐和不切实际的。本文应用热平衡方法的能源监测数据，估计一个参数，描述了在真实的家庭住宅的通风和渗透率的组合。这些估计值与公布的值进行比较，并提出了一个模型，该模型描述了作为用户行为（开口控制）和风速变化的函数的换气率。该文件表明，它是可能的，以估计合理的空气交换率从这样的数据。
Infiltration and ventilation rates in domestic buildings vary with construction type, weather conditions and the operation of openings in the fabric. Generating good estimates of ventilation is important for modelling, simulation and performance assessment as it has a significant impact on energy consumption. Physical tests can be applied to estimate leakage, but this is cumbersome and impractical to apply in most cases. This paper applies a heat balance approach to energy monitoring data to estimate a parameter that describes the combined ventilation and infiltration rates in real family homes. These estimates are compared with published values and a model is presented that describes the air change rate as a function of user behaviour (control of openings) and varying wind speed. The paper demonstrates that it is possible to estimate plausible air change rates from such data.
