Most of the window use models developed for building energy simulations include physical environmental variables as drivers. Even though it is a common approach to include these variables, the validity of this approach can be questioned based on observations in the literature regarding the consistency and seasonality of the relationship between these variables and the window use. Additionally, it was questioned whether this approach could capture the inter-occupant diversity. To assess the extent of the uncertainties, modelling methods from the literature were applied to a case study. The results revealed that a large share of the variance in window use can be attributed to the season and the household-ID. This indicates that the window use varied across the year but was stable within one season, and that these behaviours differed significantly between households. Thus occupants interacted with windows according to seasonal habits, more so then according to momentaneous environmental conditions.

大多数为建筑能源模拟开发的窗户使用模型都包括物理环境变量作为驱动因素。尽管包含这些变量是一种常见的方法，但根据文献中关于这些变量与窗口使用之间关系的一致性和季节性的观察，这种方法的有效性可能会受到质疑。此外，有人质疑这种方法是否可以捕捉住户间的多样性。为了评估不确定性的程度，将文献中的建模方法应用于案例研究。结果显示，窗户使用的很大一部分差异可归因于季节和家庭 ID。这表明窗口使用在一年中有所不同，但在一个季节内是稳定的，并且这些行为在家庭之间存在显着差异。因此，居住者根据季节习惯与窗户互动，比根据瞬时环境条件更是如此。
