Extreme weather events AMY weather file

Building performance simulation in extreme conditions is crucial for improving the resilience of buildings to withstand climate change-induced weather events. Using Actual Meteorological Year weather files instead of Typical Meteorological Year files allows for accurate estimation of building performance during such extreme conditions, enabling the assessment of vulnerabilities and areas that require improvement. The approach applies to both existing buildings needing climate change-resilient retrofits and new building designs that must be compatible with future climatic conditions. The intensification and frequency increase of these extreme weather events make developing adaptation and resilient-building measures imperative, involving understanding potential losses households may experience due to the intensification of extreme events. Addressing the knowledge gap caused by the absence of an AMY weather file dataset is essential for accurate BPS during past extreme climate change-induced weather events. This article introduces a comprehensive .epw format weather file dataset focusing on historical extreme weather events in Canada, encompassing a diverse array of past occurrences in various locations, allowing for better estimation of thermal performance.

极端工况下的建筑性能模拟，对于提升建筑抵御气候变化引发的极端气象事件的韧性至关重要。相较于典型气象年（Typical Meteorological Year, TMY）气象文件，采用实际气象年（Actual Meteorological Year, AMY）气象文件可精准估算此类极端工况下的建筑性能，从而实现对建筑脆弱点与需优化区域的评估。该方法既适用于需要开展气候变化韧性改造的既有建筑，也适用于需适配未来气候条件的新建建筑设计方案。当前极端气象事件强度加剧、发生频次提升，使得制定适应策略与韧性建筑措施迫在眉睫，其中需厘清极端事件加剧可能给住户带来的潜在损失。弥补因缺乏AMY气象文件数据集而造成的知识缺口，对于精准开展建筑性能模拟（Building Performance Simulation, BPS）以还原历史极端气候变化引发的气象事件至关重要。本文介绍了一套涵盖加拿大境内多区域历史极端气象事件的完整.epw格式气象文件数据集，囊括了该地区各类既往极端气象事件案例，可用于更精准的建筑热性能评估。
