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、管道和在建筑物内供应热水的连接装置。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如嗜肺军团菌的生长，消毒副产物和其他有毒化合物的产生，低效的能源消耗和水的浪费。因此，热水系统的适当管理需要跨学科的方法来避免这种不利的结果。这笔赠款将支持一个混合研讨会的费用，包括虚拟会议和为期两天的面对面研讨会，重点是热水系统设计的创新。讲习班的目标是发展与水质、公共卫生、建筑科学和能源有关的跨学科知识的共同水平。现场研讨会将推进跨学科热水系统融合研究，重点关注水质、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。预期产出包括项目报告、同行评议的手稿，以及为潜在的未来研究促进跨学科研究合作。这笔赠款将支持一个虚拟/面对面混合研讨会的费用，该研讨会的重点是热水系统设计的创新，以同时满足水质、公共卫生和保护目标。研讨会的总体目标是确定科学来评估热水系统可以重新设计为有益的分布式处理应用程序，可以显着控制和改善下水管化学和微生物水质，同时在其设计寿命内保持热效率。本次研讨会旨在实现这一目标的具体目标包括：1)促进与热水系统的基本过程及其对住宅公共卫生的影响相关的跨学科知识交流；Ii)将热水系统重新设想为一系列减少污染物的处理和实践，而不是施加污染附加费的系统；iii)促进跨学科研究小组之间的网络连接，以促进与热水系统改进和创新有关的未来研究合作。本项目成果的传播将通过一份项目报告、同行评议的手稿和编制特定地区和热水系统特定文献的参考书目来实现。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识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.
