Potential advantages in combining smart and green infrastructure over silo approaches for future cities

Yamuna KALUARACHCHI

《工程管理前沿（英文）》 2021年第8卷第1期页码 98-108 doi: 10.1007/s42524-020-0136-y

摘要： Cities are incorporating smart and green infrastructure components in their urban design policies, adapting existing and new infrastructure systems to integrate technological advances to mitigate extreme weather due to climate change. Research has illustrated that smart green infrastructure (SGI) provides not only climate change resilience but also many health and wellbeing benefits that improve the quality of life of citizens. With the growing demand for smart technology, a series of problems and challenges, including governance, privacy, and security, must be addressed. This paper explores the potential to transition from grey, green, or smart silos to work with nature-based solutions and smart technology to help change cities to achieve considerable environmental and socio-economic benefits. The concepts of grey, green, and smart infrastructure are presented, and the needs, benefits, and applications are investigated. Moreover, the advantages of using integrated smart, green nature-based solutions are discussed. A comprehensive literature review is undertaken with keyword searches, including journal papers, stakeholder and case study reports, and local authority action plans. The methodology adopts multimethod qualitative information review, including literature, case studies, expert interviews, and documentary analysis. Published data and information are analysed to capture the key concepts in implementing SGI systems, such as storm-water control, flood and coastal defense, urban waste management, transportation, recreation, and asset management. The paper investigates the elimination of silo approaches and the alleviation of the destructions caused by extreme weather events using these interdependent SGI systems supported by novel data-driven platforms to provide nature-based solutions to boost the health and wellbeing of the residents.

Quantitative analysis of impact of green stormwater infrastructures on combined sewer overflow control

Jinsong Tao, Zijian Li, Xinlai Peng, Gaoxiang Ying

《环境科学与工程前沿（英文）》 2017年第11卷第4期 doi: 10.1007/s11783-017-0952-4

摘要： Stimulated by the recent USEPA’s green stormwater infrastructure (GSI) guidance and policies, GSI systems have been widely implemented in the municipal area to control the combined sewer overflows (CSOs), also known as low impact development (LID) approaches. To quantitatively evaluate the performance of GSI systems on CSO and urban flooding control, USEPA-Stormwater Management Model (SWMM) model was adopted in this study to simulate the behaviors of GSI systems in a well-developed urban drainage area, PSW45, under different circumstances. The impact of different percentages of stormwater runoff transported from impervious surfaces to the GSI systems on CSO and urban flooding control has also been investigated. Results show that with current buildup, GSI systems in PSW45 have the best performance for low intensity and short duration events on both volume and peak flow reductions, and have the worst performance for high intensity and long duration events. Since the low intensity and short duration events are dominant from a long-term perspective, utilizing GSI systems is considered as an effective measure of CSO control to meet the long-term control strategy for PSW45 watershed. However, GSI systems are not suitable for the flooding control purpose in PSW45 due to the high occurrence possibility of urban flooding during or after high intensity events where GSI systems have relatively poor performance no matter for a short or long duration event.

Effects of green roof damping and configuration on structural seismic response

《结构与土木工程前沿（英文）》页码 1133-1144 doi: 10.1007/s11709-023-0959-9

摘要： Sustainable structures are critical for addressing global climate change. Hence, their structural resilience or ability to recover from natural events must be considered comprehensively. Green roofs are a widely used sustainable feature that improve the environment while providing excellent occupant amenity. To expand their usage, their inherent damping and layout sensitivity to seismic performance are investigated in this study. The soil of a green roof can serve as a damper to dissipate the energy generated by earthquakes or other dynamic events. Results of preliminary analysis show that a green roof soil can increase localized damping by 2.5% under both dry and saturated conditions. Based on these findings, nonlinear time-history analyses are conducted on a three-story building in SAP2000 to monitor the structural behavior with and without a green roof. The increased damping in the green roof soil is beneficial to the structural performance, i.e., it reduces the building displacement and acceleration by 10% and 12%, respectively. Additionally, certain configurations are more effective and beneficial to the structural response than others, which suggests the possibility of design optimization. Based on the findings of this study, new methods of modeling and considering green roofs in structural design are established.

Dynamic design of green stormwater infrastructure

Robert G. Traver, Ali Ebrahimian

《环境科学与工程前沿（英文）》 2017年第11卷第4期 doi: 10.1007/s11783-017-0973-z

摘要： This paper compares ongoing research results on hydrologic performance to common design and crediting criteria, and recommends a change in direction from a static to a dynamic perspective to fully credit the performance of green infrastructure. Examples used in this article are primarily stormwater control measures built for research on the campus of Villanova University [ , ]. Evidence is presented demonstrating that the common practice of crediting water volume based on soil and surface storage underestimates the performance potential, and suggests that the profession move to a more dynamic approach that incorporates exfiltration and evapotransporation. The framework for a dynamic approach is discussed, with a view to broaden our design focus by including climate, configuration and the soil surroundings. The substance of this work was presented as a keynote speech at the 2016 international Low Impact Development Conference in Beijing China [ ].

Finance infrastructure through blockchain-based tokenization

Yifeng TIAN, Zheng LU, Peter ADRIAENS, R. Edward MINCHIN, Alastair CAITHNESS, Junghoon WOO

《工程管理前沿（英文）》 2020年第7卷第4期页码 485-499 doi: 10.1007/s42524-020-0140-2

摘要： The infrastructure finance gap has long-standing implications for economic and social development. Owing to low efficiency, high transaction costs, and long transaction time, conventional infrastructure financing instruments are considered to be major contributors to the increasing mismatch between the need for infrastructure development and available financing. Implemented through smart contracts, blockchain tokenization has shown characteristics that are poised to change the capital stack of infrastructure investment. This study analyzed the first SEC-compliant energy asset security token, ZiyenCoin, from the perspective of the key participants, relevant regulations, and token offering procedures. Results show that tokenization can improve infrastructure assets liquidity, transaction efficiency, and transparency across intermediaries. Conventional infrastructure financing instruments were compared with blockchain tokenization by reviewing the literature on infrastructure finance. The benefits and barriers of tokenizing infrastructure assets were thoroughly discussed to devise ways of improving infrastructure financing. The study also found that the potential of tokenization has not yet been fully realized because of the limited technical infrastructures, regulation uncertainties, volatilities in the token market, and absence of the public sector. This study contributes to the present understanding of how blockchain technology can be implemented in infrastructure finance and the role of tokenization in the structure of public–private partnership and project finance.

《工程（英文）》 2016年第2卷第4期页码 414-425 doi: 10.1016/J.ENG.2016.04.014

摘要：

预计到2020 年，中国的绿色投资需求将达到每年1.7 万亿~2.9 万亿元人民币( 折合2740 亿~4680 亿美元)。对经济需求的评估已经提供给了众多的行业，包括可持续能源、基础设施建设( 包括环境保护)、环境修复、工业污染控制、能源和水资源效率以及绿色产品。中国的绿色财政的背景已经在讨论之中，覆盖了城镇化、气候改变、基础设施交互以及工业模式的转变。很多基础设施建设的融资发生在城市中，聚焦在《国家新型城镇化规划(2014—2020 年)》下的公平、环境保护以及生活质量问题。中国在建筑行业已经实施了很多成功的政策，但是中国的建筑节能仍有相当大的提升空间。中国目前正在追求低碳的增长战略，这与中国的整体环境和生活质量目标一致。到2020 年之后，中国作为一个生态文明国家的未来将建立在一个中央基础设施政策的实施上，这个政策就是《中国2050 高比例可再生能源发展情景暨路径研究》。以《循环经济发展战略及近期行动计划》为例，中国绿色工业转型的关键一步涉及节约材料的工程系统，以此减少甚至清除废料。为了更好地理解中国经济在其绿色转型中的改变，以及释放其巨大的潜在资金来源，有必要对中国所有的基础设施部门进行更加全面的研究，尤其是货运铁路的基础设施和港口。要清理土壤和地下水中的环境污染残留物，以及减少工业污染，都需要巨大的投资。电力行业摒弃煤炭的转型将会避免一些工业治理成本。工程师在计划、设计和构造中国新绿色基础设施中的贡献，也同样会在理解了宽松的政策环境以及土地利用、基础设施和环保成效间的相互作用后更进一步。

On water security, sustainability, and the water-food-energy-climate nexus

Michael Bruce BECK, Rodrigo VILLARROEL WALKER

《环境科学与工程前沿（英文）》 2013年第7卷第5期页码 626-639 doi: 10.1007/s11783-013-0548-6

摘要： The role of water security in sustainable development and in the nexus of water, food, energy and climate interactions is examined from the starting point of the definition of water security offered by Grey and Sadoff. Much about the notion of security has to do with the presumption of scarcity in the resources required to meet human needs. The treatment of scarcity in mainstream economics is in turn examined, therefore, in relation to how each of us as individuals reconciles means with ends, a procedure at the core of the idea of sustainable development. According to the Grey-Sadoff definition, attaining water security amounts to achieving basic, single-sector water development as a precursor of more general, self-sustaining, multi-sectoral development. This is consistent with the way in which water is treated as “first among equals”, i.e. privileged, in thinking about what is key in achieving security around the nexus of water, food, energy and climate. Cities, of course, are locations where demands for these multiple resource-energy flows are increasingly being generated. The paper discusses two important facets of security, i.e., diversity of access to resources and services (such as sanitation) and resilience in the behavior of coupled human-built-natural systems. Eight quasi-operational principles, by which to gauge nexus security with respect to city buildings and infrastructure, are developed.
