Workshop on innovation in hot water system design to meet simultaneous water quality, public health, and conservation objectives

热水系统包括热水器、管道和连接的装置，以在建筑物内供应热水。这些系统需要性能要求和风险权衡的复杂相互作用，同时提供适当温度、压力、化学和微生物水质的热水，以保护人类健康。热水系统的不当操作可能导致管道病原体的生长，如嗜肺军团菌、消毒副产品和其他有毒化合物的产生、低效率的能源消耗和水的浪费。因此，热水系统的适当管理需要采取跨学科的方法，以避免这种不利后果。这笔赠款将资助一个由虚拟会议和为期两天的面对面讲习班组成的混合讲习班的费用，讲习班的重点是热水系统设计方面的创新。研讨会的目标是发展与水质、公共卫生、建筑科学和能源相关的各学科的共同知识水平。面对面的研讨会将推动跨学科热水系统融合研究，重点是水质、能源效率，以及通过控制军团菌和其他病原体保护人类健康。预期的产出是一份项目报告、同行评审的手稿，以及促进未来潜在研究的跨学科研究合作。这笔赠款将支持虚拟/面对面混合研讨会的费用，该研讨会侧重于热水系统设计的创新，以满足同时实现水质、公共健康和保护目标。研讨会的总体目标是确定科学，以评估热水系统可被重新设计为有益的分布式处理应用程序的假设，这些应用程序可显著控制和改善下管道化学和微生物水质，同时在其设计生命周期内仍保持热效率。为实现这一目标而举办的讲习班的具体目标包括：i)促进与热水系统有关的基本过程及其对居民公共健康的影响方面的跨学科知识交流；ii)将热水系统重新设想为减少污染物的一系列处理方法和做法，而不是征收污染物附加费的系统；iii)促进跨学科研究人员团体之间的网络联系，以便今后开展与热水系统改进和创新有关的研究合作。该项目成果的传播将通过项目报告、同行评议的手稿和编写特定地区和热水系统特定文献的书目来实现。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。

Hot water systems include water heaters, pipes, and connected fixtures to supply hot water within buildings. These systems require a complex interplay of performance requirements and risk trade-offs, while supplying hot water of appropriate temperature, pressure, chemical, and microbiological water quality to protect human health. Improper operation of hot water systems can lead to the growth of plumbing pathogens like Legionella pneumophila, production of disinfection byproducts and other toxic compounds, inefficient energy consumption, and water wastage. Proper management of hot water systems thus requires a cross disciplinary approach to avoid such adverse outcomes. This grant will support costs for a hybrid workshop consisting of virtual meetings and a two-day in-person workshop focused on innovations in hot water system design. The goal of the workshop is to develop a common level of knowledge across disciplines related to water quality, public health, building science, and energy. The in-person workshop will advance interdisciplinary hot water system convergence research focused on water quality, energy efficiency, and protection of human health through the control of Legionella and other pathogens. Expected outputs are a project report, peer reviewed manuscripts, and facilitation of interdisciplinary research collaborations for potential future research. This grant will support costs for a blended virtual/in-person workshop focused on innovation in hot water system design to meet simultaneous water quality, public health, and conservation objectives. The overall goal of the workshop is to identify the science to assess the hypothesis that hot water systems can be reengineered as beneficial and distributed treatment applications that significantly control and improve downpipe chemical and microbial water quality while still maintaining thermal efficiency through their design life. The specific goals of this workshop designed to achieve this goal include a focus on i) facilitating interdisciplinary knowledge exchange related to the fundamental processes involved in hot water systems and their impact on residential public health; ii) reimagining hot water systems as a series of treatments and practices that reduce the contaminants rather a system that exerts a contamination surcharge; and iii) catalyzing networking between groups of interdisciplinary researchers for future research collaborations related to hot water system improvements and innovation. Dissemination of results from this project will be achieved through a project report, peer reviewed manuscripts, and compilation of a bibliography of area-specific and hot water system specific literature.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
