Flood damage functions are important tools used to estimate potential damage to the built environment from various types of flood‐related hazard events (e.g., hurricanes, riverine flooding). Oftentimes these damage estimates are used to determine the feasibility of flood protection or mitigation projects or to plan for future disasters. While existing standardised functions are used to estimate potential economic loss for residential buildings, functions can be customised to assess the environmental impacts of flood damages for specific building designs. This study presents a methodology for customising functions to estimate the carbon footprint of flood‐related building repairs. Unlike regular home repairs, which are based on material life expectancy, flood repairs are dependent on the severity of the flood hazard (i.e., flood depth) and probability of hazard occurrence within the lifespan of a building. To demonstrate the methodology, customised functions are developed for a case study home design in Saint Petersburg, Florida.

自定义洪水破坏功能以估算与洪水相关的房屋维修的碳足迹

洪水破坏功能是重要的工具，可用于评估各种类型的与洪水有关的灾害事件（例如，飓风，河流洪水）对建筑环境的潜在破坏。通常，这些损害估计数用于确定防洪或减灾项目的可行性或计划未来的灾难。使用现有的标准化功能来估算住宅建筑物的潜在经济损失时，可以对功能进行定制以评估特定建筑物设计的洪水破坏对环境的影响。这项研究提出了一种定制功能的方法，以估算与洪水有关的建筑物维修的碳足迹。与基于材料预期寿命的定期房屋维修不同，洪水维修取决于洪水灾害的严重性（即，洪水深度）和建筑物使用寿命内发生危险的可能性。为了演示该方法，针对佛罗里达州圣彼得堡的案例研究房屋设计开发了定制功能。
