Large outdoor fires present a risk to the built environment. Examples often in the international media reports are wildfires that spread into communities, referred to as Wildland-Urban Interface (WUI) fires. WUI fires have destroyed communities throughout the world and are a growing problem in fire safety science. Other examples are large urban fires, including those that have occurred after earthquakes. Over the past several decades, fire safety science research has spent a great deal of effort to understand fire dynamics within buildings. Research into large outdoor fires, and how to potentially mitigate the loss of structures in such fires, lags behind other areas of fire safety science research [1]. Fire spread in large outdoor fires is incredibly complex, involving the interaction of topography, weather, and fuels. At the same time, common characteristics between fire spread in WUI fires and urban fires have not been fully exploited. Once a wildland fire reaches a community and ignites structures, structure-structure fire spread can occur under similar mechanisms as in urban fire spread. On June 11, 2017, a workshop, sponsored by the International Association for Fire Safety Science (IAFSS), was held. Seven panelists from around the world presented regional overviews of the large outdoor fire problem related to the built environment in their respective regions. Presentations explored common characteristics between these fires and were arranged as: European View, Asian View, North American View, South American View, and Oceania View. A significant discussion outcome of the workshop was the desire of the participants to make this topic a permanent working group under the umbrella of the International Association for Fire Safety Science (IAFSS). So far, this has been done for only one other topic, the Measurement and Computation of Fire Phenomena (MaCFP) working group [2], supporting modeling, a far more well-characterized and studied topic in fire safety science. Due to structure and organization of the workshop, it was apparent that large outdoor fires and the built environment encompass far more than only wildfires, and the working group will address problems with key phenomenological shared characteristics relevant to both urban fires, and wildland-urban interface (WUI) fires. Overall, the workshop was considered a fruitful endeavor and clearly highlighted that much needs to be done in this research area, as it is far behind the well-studied topics that have been around in fire safety science for decades. Many next generation researchers attended and were encouraged to work in this area, as research impact is possible. Amanuscript has been submitted to the official journal of the IAFSS to

大型室外火灾和建筑环境：IAFSS 常设工作组的目的和目标


大型户外火灾对建筑环境构成风险。国际媒体报道中经常出现的例子是蔓延到社区的野火，称为荒地-城市界面（WUI）火灾。 WUI 火灾摧毁了世界各地的社区，并成为消防安全科学中日益严重的问题。其他例子包括大型城市火灾，包括地震后发生的火灾。在过去的几十年里，消防安全科学研究花费了大量的精力来了解建筑物内的火灾动态。对大型室外火灾以及如何潜在地减轻此类火灾中建筑物损失的研究落后于消防安全科学研究的其他领域[1]。大型室外火灾的火势蔓延极其复杂，涉及地形、天气和燃料的相互作用。与此同时，WUI火灾与城市火灾的火势蔓延的共同特征尚未得到充分利用。一旦野火蔓延到社区并点燃建筑物，结构间火灾蔓延可能会在与城市火灾蔓延类似的机制下发生。 2017年6月11日，由国际消防安全科学协会（IAFSS）主办的研讨会举行。来自世界各地的七位小组成员介绍了各自地区与建筑环境相关的大型户外火灾问题的区域概况。演示探讨了这些火灾之间的共同特征，并按以下顺序排列：欧洲视图、亚洲视图、北美视图、南美视图和大洋洲视图。研讨会的一个重要讨论成果是与会者希望将该主题成为国际消防安全科学协会 (IAFSS) 旗下的常设工作组。 到目前为止，这只是针对另一个主题，即火灾现象的测量和计算 (MaCFP) 工作组 [2]，支持建模，这是消防安全科学中一个更加充分表征和研究的主题。由于研讨会的结构和组织，很明显，大型室外火灾和建筑环境不仅仅包括野火，工作组将解决与城市火灾和荒地与城市界面相关的关键现象学共同特征的问题（WUI）火灾。总体而言，该研讨会被认为是一次富有成效的努力，并明确强调该研究领域需要做很多工作，因为它远远落后于消防安全科学几十年来经过充分研究的主题。许多下一代研究人员出席并被鼓励在这一领域工作，因为研究影响是可能的。Amanuscript 已提交至 IAFSS 官方期刊
