Moisture is a dominant agent in the degradation of building components. To assess degradation phenomena in building envelopes, hygrothermal simulations are performed. The hygrothermal behaviour of building envelopes depends on the outdoor climate conditions. Therefore, it is important to use climate data near the location of interest when running hygrothermal simulations. There are no appropriate climate data for hygrothermal simulations of Belgian cities. Therefore, we created two types of climate files for Brussels, i.e. the capital of Belgium. This paper presents the climate data that are selected based on the framework developed by Vandemeulebroucke et al. The first climate file is a long-term 30-year climate file. Using this climate file is the most reliable, but computationally expensive. This climate file is recommended for academics having sufficient computational power. The second file is a Moisture Reference Year (MRY), which is one year of climate data that represents the 90th percentile of moisture stress on building envelopes. The MRY is selected based on a climate index that is critical for many applications, i.e. the free wind-driven rain load. The reference year is called a generic climate-based MRY. The latter climate file is recommended for building consultants or academics performing very large studies, as it requires less computational power at the cost of a lower level of detail.
水分是建筑构件降解的主要因素。为了评估建筑围护结构中的降解现象，进行了湿热模拟。建筑围护结构的湿热行为取决于室外气候条件。因此，在运行湿热模拟时，使用感兴趣地点附近的气候数据非常重要。对于比利时城市的湿热模拟，没有合适的气候数据。因此，我们为比利时首都布鲁塞尔创建了两种类型的气候文件。本文介绍了根据范德默勒布罗克等人制定的框架选择的气候数据。第一个气候文件是一个为期30年的长期气候文件。使用这个气候文件是最可靠的，但计算成本很高。建议有足够计算能力的学者使用此气候文件。第二个文件是湿度参考年（MRY），它是一年的气候数据，代表建筑围护结构上湿度应力的第90百分位数。MRY是根据对许多应用至关重要的气候指数，即自由风致雨荷载来选择的。该参考年称为通用的基于气候的MRY。后一种气候文件推荐给进行非常大型研究的建筑顾问或学者，因为它需要较少的计算能力，但细节程度较低。
