Understanding building-occupant-microbiome interactions toward healthy built environments: A review

Shuai Li, Zhiyao Yang, Da Hu, Liu Cao, Qiang He

《环境科学与工程前沿(英文)》 2021年 第15卷 第4期 doi: 10.1007/s11783-020-1357-3

摘要: Abstract • The built environment, occupants, and microbiomes constitute an integrated ecosystem. • This review summarizes research progress which has focused primarily on microbiomes. • Critical research needs include studying impacts of occupant behaviors on microbiomes. Built environments, occupants, and microbiomes constitute a system of ecosystems with extensive interactions that impact one another. Understanding the interactions between these systems is essential to develop strategies for effective management of the built environment and its inhabitants to enhance public health and well-being. Numerous studies have been conducted to characterize the microbiomes of the built environment. This review summarizes current progress in understanding the interactions between attributes of built environments and occupant behaviors that shape the structure and dynamics of indoor microbial communities. In addition, this review also discusses the challenges and future research needs in the field of microbiomes of the built environment that necessitate research beyond the basic characterization of microbiomes in order to gain an understanding of the causal mechanisms between the built environment, occupants, and microbiomes, which will provide a knowledge base for the development of transformative intervention strategies toward healthy built environments. The pressing need to control the transmission of SARS-CoV-2 in indoor environments highlights the urgency and significance of understanding the complex interactions between the built environment, occupants, and microbiomes, which is the focus of this review.

摘要:
安全气囊是有效的汽车乘员安全防护装置,但是乘员可能因为气囊点火展开时的巨大能量而受到意外伤害。本文从减少气体发生剂用量的角度对一种新型管式安全气囊进行设计;为研究新型气囊的刚度与防护效果,挑选3 种类型的假人进行计算机仿真;之后,针对第50 百分位假人进行多目标优化分析。结果显示,新型气囊的静态体积约为普通气囊的1/3,并且在气体发生剂用量至少减少30% 的情况下,每种假人的损伤值均能够满足法规要求。优化分析后,复合损伤指标(Pcomb)概率下降22%,且充气量最优解减少32%。本文结果表明,在减少气体发生剂用量的情况下,新型管式安全气囊在乘员防护方面仍具有较大的潜力。

Digital twin for healthy indoor environment: A vision for the post-pandemic era

《工程管理前沿(英文)》 2023年 第10卷 第2期   页码 300-318 doi: 10.1007/s42524-022-0244-y

摘要: Indoor environment has significant impacts on human health as people spend 90% of their time indoors. The COVID-19 pandemic and the increased public health awareness have further elevated the urgency for cultivating and maintaining a healthy indoor environment. The advancement in emerging digital twin technologies including building information modeling (BIM), Internet of Things (IoT), data analytics, and smart control have led to new opportunities for building design and operation. Despite the numerous studies on developing methods for creating digital twins and enabling new functionalities and services in smart building management, very few have focused on the health of indoor environment. There is a critical need for understanding and envisaging how digital twin paradigms can be geared towards healthy indoor environment. Therefore, this study reviews the techniques for developing digital twins and discusses how the techniques can be customized to contribute to public health. Specifically, the current applications of BIM, IoT sensing, data analytics, and smart building control technologies for building digital twins are reviewed, and the knowledge gaps and limitations are discussed to guide future research for improving environmental and occupant health. Moreover, this paper elaborates a vision for future research on integrated digital twins for a healthy indoor environment with special considerations of the above four emerging techniques and issues. This review contributes to the body of knowledge by advocating for the consideration of health in digital twin modeling and smart building services and presenting the research roadmap for digital twin-enabled healthy indoor environment.

长大公路隧道火灾安全疏散性能化设计与分析

摘要:

基于性能化防火设计方法, 分析火灾条件下长大公路隧道内人 员疏散行为的特点,给出隧道内人 员疏散的安全判据,并结合某隧道 的结构及车流特征对人员疏散过程 进行了数值模拟研究,分析隧道在 正常通车和局部行车堵塞时,不同 火源位置、横通道间距与横通道宽 度对人员疏散时间及安全状态的影 响。结果表明,与建筑内人员疏散不 同,长大公路隧道内火灾的可用安 全疏散时间(ASET)与需要的安全疏 散时间(RSET)均为沿隧道长度方向 位置的函数。隧道内人员安全疏散 的时间曲线在各横通道疏散口出现 峰值,这主要是受到横通道通行能 力的限制,各疏散口人员集聚等待 所致。当隧道发生局部堵塞时,横 通道口需要的安全疏散时间显著增 加,危险性也急剧增大。隧道内人 员疏散的性能化防火设计应综合考 虑火源位置对人员载荷及疏散口位 置可用安全疏散时间的影响。该研 究为公路隧道火灾安全疏散设施的 优化设计提供依据。

摘要:

根据某大型超市的建筑设计方案以及人员分布情况,针对该超市各防火分区之间疏散楼梯分布不均 匀的问题,提出2种改进设计方案。一种是改进防火分区设置,在相邻防火分区之间设置共用楼梯,使得防火分区的疏散宽度分布更均匀,另一种是缩小相关防火分区的面积从而增加一个防火分区。采用EVACNET4进行计算机模拟,得到了3种疏散场景下人员疏散的时间。计算结果表明,当防火分区面积比较大时,疏散楼梯在防火分区四周均匀分布有利于人员疏散;共用楼梯的设置,既有利于人员疏散,又可以提高楼梯的利用率;适当减小防火分区的面积可以

摘要: This paper contributes an inclusive review of scientific studies in the field of sustainable human building ecosystems (SHBEs). Reducing energy consumption by making buildings more energy efficient has been touted as an easily attainable approach to promoting carbon-neutral energy societies. Yet, despite significant progress in research and technology development, for new buildings, as energy codes are getting more stringent, more and more technologies, e.g., LED lighting, VRF systems, smart plugs, occupancy-based controls, are used. Nevertheless, the adoption of energy efficient measures in buildings is still limited in the larger context of the developing countries and middle income/low-income population. The objective of Sustainable Human Building Ecosystem Research Coordination Network (SHBE-RCN) is to expand synergistic investigative podium in order to subdue barriers in engineering, architectural design, social and economic perspectives that hinder wider application, adoption and subsequent performance of sustainable building solutions by recognizing the essential role of human behaviors within building-scale ecosystems. Expected long-term outcomes of SHBE-RCN are collaborative ideas for transformative technologies, designs and methods of adoption for future design, construction and operation of sustainable buildings.
