Spatial-temporal patterns and influencing factors of the Building Green View Index: A new approach for quantifying 3D urban greenery visibility

建筑绿视指数的时空模式及影响因素:一种量化3D城市绿化可视性的创新方法


【摘要】

The vertical expansion of urbanization has increased the morphological heterogeneity of the urban landscape, affecting the physical and emotional wellbeing of urban dwellers by obstructing the view of greenery. In this study, multisource spatial data was used to calculate the Building Green View Index (BGVI). Baidu Street View (BSV) images were collected for comparison with the corresponding BGVI results. A random forest model was used to analyze the contributions and marginal effects of multiple influencing factors on BGVI. The results indicated that approximately 76.10 % of the sampled sites had a higher BGVI than the street view green view index, indicating buildings' superiority of visible greenery in height. The western edge of the research region frequently had the highest BGVI. Meanwhile, the hotspot regions were primarily located in the west, which was more consistent with the distribution of high value zones. The green area within the maximum visible distance, the maximum visible distance, and the average height were the most influential factors of BGVI according to marginal effects analysis with the highest IncNodePurity. As a quantitative measure of urban dwellers’ visual accessibility to green space, the BGVI will contribute to urban green planning and the development of landscape architecture.

城市化的垂直扩展增加了城市景观的形态异质性,通过遮挡绿化景观影响了城市居民的身心健康。在本研究中,使用多源空间数据计算了建筑绿视率(BGVI)。收集了百度街景(BSV)图像,并将其与相应的BGVI结果进行比较。采用随机森林模型分析了多个影响因素对BGVI的贡献及其边际效应。研究结果表明,大约76.10%的采样点的BGVI高于街景绿视率,表明建筑在高度上的可见绿化具有优势。研究区域的西缘经常具有最高的BGVI,而热点区域主要位于西部,这与高值区域的分布更加一致。根据具有最高节点纯度(IncNodePurity)的边际效应分析,最大可见距离内的绿化面积、最大可见距离和平均高度是对BGVI影响最大的因素。作为衡量城市居民对绿色空间视觉可达性的定量指标,BGVI将有助于城市绿地规划和景观建筑的发展。

Integrating GIS, agent-based, and discrete event simulation to evaluate patient distribution policies for enhancing urban healthcare access network resilience

集成GIS、基于代理的离散事件模拟评估患者分布政策以增强城市医疗保健接入网络的韧性


【摘要】

Ensuring healthcare network resilience during urban disasters is crucial for sustainability and public safety. This study evaluates patient distribution policies in healthcare networks through a case study following a simulated earthquake scenario to enhance resilience during such events. By integrating geographic information systems (GIS) to model road impacts, agent-based modeling (ABM) for patient movements, and discrete event simulation (DES) for hospital queues, six distribution policies were evaluated. The analysis prioritized two metrics: patient waiting times and unmet treatment demands within four days post-disaster. Results revealed that policies emphasizing minimal hospital wait times demonstrated superior performance, reducing average waiting times by 71% and unmet demands compared to proximity-based approaches. Sensitivity analyses highlighted human behavior's influence, with increased personal vehicle usage adversely impacting resilience. Conversely, expanding hospital capacities substantially improved resilience indicators. The findings underscore the importance of informed policymaking focused on wait time reduction to enhance healthcare access resilience. Incorporating real-time hospital wait times into ambulance dispatch decisions emerged as a promising strategy. This multi-method simulation approach provides valuable insights into optimizing emergency response for resilient urban healthcare systems.

确保城市灾害期间医疗网络的韧性对于可持续性和公共安全至关重要。本研究通过模拟地震场景的案例研究,评估医疗网络中的病人分配政策,以增强灾害期间的韧性。研究整合了地理信息系统(GIS)来模拟道路影响,基于代理的建模(ABM)用于模拟病人的流动,以及离散事件模拟(DES)用于医院排队管理,评估了六种分配政策。分析重点关注两个指标:灾后四天内的病人等待时间和未满足的治疗需求。结果表明,强调最小化医院等待时间的政策表现出色,平均等待时间减少了71%,未满足需求相比基于邻近性的方案显著减少。敏感性分析突出了人类行为的影响,个人车辆使用量的增加对韧性产生了不利影响。相反,扩展医院容量显著改善了韧性指标。研究结果强调了制定以减少等待时间为重点的政策对提升医疗服务韧性的重要性。将实时医院等待时间纳入救护车调度决策中被视为一种有前途的策略。这种多方法的模拟研究为优化应急响应以构建韧性的城市医疗系统提供了宝贵的见解。

Sustaining power distribution network submerged in plug-in hybrid CNG-electric vehicles for future green transportation: A risk-constrained analysis

未来绿色交通中的插电式混合动力CNG电动车对电力分配网络的可持续性:一种风险约束分析


【摘要】

The urgent need to address environmental issues, particularly the reduction of greenhouse gas emissions, has become a global priority. In this pursuit, various technologies are being explored to facilitate the promotion of sustainability. This study focuses on a virtual energy hub (VEH) integrated with Plug-in hybrid gas-electric vehicles (PHGEVs), various energy sources, and storage devices. However, the presence of fossil-based energy sources like combined heat and power (CHP), diesel generation (DG), boilers, and gas-based operation modes of PHGEVs, resulted in the release of carbon emissions. In this concern, the power-to-gas (P2G) technology, with its immense potential, is being considered to absorb and recycle captured CO2 emissions into methane gas, thereby enhancing economic and sustainability perspectives. Furthermore, uncertain parameters including the charge and discharge of PHGEVs, the price of the day-ahead market for heat and power, energy demands, and wind speed are considered in the VEH, the management of which is achieved through the downside risk constraint (DRC) method. The proposed model is implemented and tested on an IEEE 33-bus test system. Results show that P2G reduces the CO2 level by a mean of 3.7 %. Also, for the minimum of 3.2 % profit reduction, the risk level has fallen by nearly 100 %.

紧急应对环境问题,特别是减少温室气体排放,已成为全球优先事项。在这一追求中,各种技术正在被探索以促进可持续发展。本研究集中于一个虚拟能源中心(VEH),该中心集成了插电式混合动力气电车辆(PHGEVs)、各种能源来源和储存设备。然而,像联合热电(CHP)、柴油发电(DG)、锅炉以及PHGEVs的燃气操作模式等基于化石燃料的能源源会导致碳排放。在这种情况下,具有巨大潜力的电力气体(P2G)技术被考虑用于吸收并回收捕获的二氧化碳排放,将其转化为甲烷气体,从而提高经济性和可持续性视角。此外,VEH中考虑了不确定参数,包括PHGEVs的充放电、前瞻市场的热力和电力价格、能源需求和风速,其管理通过下行风险约束(DRC)方法实现。该模型在IEEE 33节点测试系统上进行了实施和测试。结果显示,P2G技术使CO2水平平均降低了3.7%。同时,在最低3.2%的利润减少下,风险水平几乎降到了100%。

Regional-scale energy-water nexus framework to assess the GHG emissions under climate change and development scenarios via system dynamics approach

区域尺度能源-水系统框架:通过系统动力学方法评估气候变化和发展情景下的温室气体排放


【摘要】

Nowadays, the consumption of natural resources is increasing due to population growth, climate change, and development. Considering the crucial impacts of the regional characteristics, this study develops an energy-water-emissions (EWE) nexus model using a system dynamics (SD) framework to assess the pattern of greenhouse gas (GHG) emissions. The model simulates regional GHG emissions (including indirect emissions of the electricity sector) under climate change and development scenarios from 2011 to 2031. The results indicate that total emissions are projected to increase in the future, while water-related emissions are expected to decrease. The study highlights the limitations of global assumptions at the regional scale, emphasizing the need for planning based on specific regional scale conditions. Through evaluating different development scenarios, the energy-saving scenario had the greatest impact on reducing emissions and resource consumption. Additionally, the results showed that development scenarios had varying effects in each region, highlighting the importance of defining region-specific development scenarios separately. This study offers policymakers valuable insights to enhance their understanding of the climate change effects to evaluate a range of development scenarios more effectively.

如今,由于人口增长、气候变化和发展,自然资源的消耗正在增加。考虑到区域特征的关键影响,本研究开发了一个能源-水资源-排放(EWE)联系模型,使用系统动力学(SD)框架来评估温室气体(GHG)排放模式。该模型模拟了2011年至2031年间,在气候变化和发展情景下的区域GHG排放(包括电力部门的间接排放)。结果表明,总排放预计将来会增加,而水资源相关排放预计会减少。研究强调了全球假设在区域尺度上的局限性,强调了基于具体区域条件进行规划的必要性。通过评估不同的发展情景,节能情景对减少排放和资源消耗的影响最大。此外,结果还显示,不同的开发情景在各个地区的影响各异,突显了分别定义区域特定发展情景的重要性。本研究为政策制定者提供了宝贵的见解,以增强他们对气候变化影响的理解,从而更有效地评估各种发展情景。

Sustainable urban noise monitoring network with renewable bioenergy sources: An energy cost–benefit analysis

基于可再生生物能源来源的可持续城市噪声监测网络:能源成本-效益分析


【摘要】

Wireless sensor networks (WSNs) have emerged as solutions for developing financially viable, and environmentally friendly monitoring systems in line with the sustainable development goals. However, their long-term operating costs are commonly neglected in literature. In this study, a novel framework for analyzing the cost–benefit trade-offs of urban noise monitoring systems is presented. The framework employs a comparative analysis of WSNs powered by bioenergy plant microbial fuel cells (PMFCs), solar photovoltaic cells, and battery sources. The network sustainability and cost–benefit effects are evaluated through the deployment of ten wireless nodes in Merida City, Mexico. The analysis of the network operational cost, the cost of upgrading technology, the system maintenance, and the battery disposal, as well as, waste savings with the bioenergy source, are considered. The analysis shows that when assessing a Long Range (LoRa) network with a PMFC bioenergy source over a 3-year period, and with a service cost set at $0.01 USD per month for each single data packet transmitted every 5 min, the investment return is attained in 8 months and delivers a profit of approximately 30% within the first year. Compared to conventional battery-powered systems, the PMFC offers significant cost savings, reducing the system cost up to 29%.

Spatio-temporal patterns of heat index and heat-related Emergency Medical Services (EMS)

热指数和与热相关的紧急医疗服务(EMS)的时空模式


【摘要】

Despite growing concerns about heat waves due to climate change and their health impacts, there has been limited research on patterns of extreme heat during summertime and their association with heat-related Emergency Medical Services (EMS) incidents. This study examines spatiotemporal patterns of the heat index (HI) and its relationship to heat-related EMS incidents in Austin-Travis County, Texas, focusing on the summers of 2020 and 2021. Collecting 47,838 heat-related EMS incidence cases and aggregating them at the tract level (N = 290), the research employs spatiotemporal analysis, spatial autocorrelation, K-means clustering, and geographically weighted Poisson regression to identify disparities in heat-related health outcomes. Key findings indicate a significant correlation between high HI frequency and intensity and increased EMS incidents, particularly in East Austin, underscoring the area's heightened vulnerability to heat. The study also reveals that heat vulnerability and urban growth patterns are closely linked to the incidence of heat-related illnesses, and its impact varies by region. These results emphasize the critical need for targeted heat resilience strategies in urban planning and emergency response. This research merges socio-economic and environmental data to offer insights into heat-related health risks, informing targeted public health policies and urban planning for more equitable and effective interventions.

Exploring spatial pattern optimization path of urban building carbon emission based on low-carbon cities analytical framework: A case study of Xi'an, China

基于低碳城市分析框架的城市建筑碳排放空间模式优化路径探索:以中国西安为例


【摘要】

Reducing carbon dioxide emissions has become a prominent issue in city construction. Here, with the objective of spatial pattern optimization, we propose a comprehensive evaluation framework for low-carbon cities. To shed further light on the mechanism by which green finance facilitates the low-carbon transformation of the economy, we chose Xi'an as a study area, used the system dynamics model, simulated the relationship between different factors in the development of low-carbon cities, and provided guidance for spatial planning of low-carbon cities. Through systematic analysis of results, we found that with the progress of urbanization and the improvement of people's living standards, the carbon emissions from urban buildings in Xi'an will increase annually and reach 2.47 million tons by 2030. In scenario 1, the faster pace of urbanization raises carbon emissions from urban buildings by 3 %, to 2.5543 million tons from the base. In contrast, in Scenario 2, the reduction in urbanization rate results in a decrease in urban building carbon emissions to 2.4243 million tons, a reduction of 2.26 % compared to the baseline scenario. Thus it can be seen that diverse modifications of parameters exert distinct effects on the ultimate carbon emissions from urban buildings.

减少二氧化碳排放已成为城市建设中的一个重要问题。为优化空间模式,我们提出了一个全面的低碳城市评估框架。为了进一步阐明绿色金融如何促进经济的低碳转型,我们选择了西安作为研究区域,使用系统动态模型模拟了低碳城市发展中不同因素之间的关系,并为低碳城市的空间规划提供了指导。通过对结果进行系统分析,我们发现随着城市化进程的推进和人们生活水平的提高,西安的城市建筑碳排放将逐年增加,并预计到2030年达到247万吨。在情景1中,城市化进程加快使得城市建筑的碳排放比基准值增加了3%,达到255.43万吨。相比之下,在情景2中,城市化速度的降低使得城市建筑碳排放减少至242.43万吨,比基准情景减少了2.26%。由此可见,参数的不同调整对城市建筑最终的碳排放产生了不同的影响。

Optimizing routing and scheduling of shared autonomous electric taxis considering capacity constrained parking facilities

容量受限停车设施的共享自动驾驶电动出租车的路径优化和调度


【摘要】

This paper focuses on routing and scheduling of autonomous electric vehicles to provide reservation-based shared ride services, while a set of parking facilities with limited capacity are used for vehicle intermittent charging. A mixed-integer linear program model is formulated in the form of a vehicle routing problem with satellite facilities (VRPSF), subject to a series of additional time and capacity-related constraints. The objective of the model is to minimize the total operating costs of the system, including those related to vehicle miles traveled and the deployed vehicle fleet size. The number of vehicles inside each parking facility is tracked so as to ensure that the capacity is never exceeded throughout the service horizon. A customized solution method based on an adaptive large neighborhood search algorithm with an explicit treatment of parking facility choices is developed. A series of numerical experiments, consisting of both hypothetical examples and a real-world case study in Hangzhou, China, have been conducted to evaluate the effectiveness and applicability of the proposed model and algorithm. The results demonstrate that ride-sharing services and parking facilities have the potential to significantly reduce the total vehicle energy consumption and operating costs for a shared autonomous electric taxi (SAET) operator in practical scenarios.

A cloud-oriented data-analysis framework to analyze peak demand dynamics in institutional building clusters

面向云的数据分析框架:分析机构建筑群中的峰值需求动态


【摘要】

Peak loads in higher education institutional building clusters (IBCs) possess considerable economic repercussions on their overall operations. Thus, identifying electrically inefficient buildings presents a significant opportunity to curtail peak loads and promote energy efficiency in IBCs. Existing literature implements clustering algorithms to comprehend the electrical demand dynamics of buildings to analyze disparity in their load behavior. These techniques perform well in single building environment, however, fall short in comprehending the demand dynamics for building clusters, specifically during peak loads. This study introduces a cloud-oriented quantile-based data analysis framework, specifically designed for simultaneously evaluating demand profiles of multiple buildings within IBCs. Quantile-based metrics namely, Value-at-Risk, Conditional Value-at-Risk and Conditional Value-at-Risk standard deviation are implemented to comprehend the electrical fluctuations and quantify the electrical impact of each building during campus-wide peak demands. A cross-building comparison is established by linearly ranking buildings following two key criteria: (i) buildings with frequent demand fluctuations and (ii) buildings exerting a high electrical impact on overall IBC demand. Both criteria are equally weighted while ranking to identify the most inefficient buildings during peak loads. The framework is implemented in a Canadian university and resulted a substantial 50 MW demand reduction through recommissioning and retrofitting of inefficient buildings.

高等教育机构建筑群(IBC)的峰值负荷对其整体运营产生了显著的经济影响。因此,识别电力效率低下的建筑物是减少峰值负荷和促进IBC能源效率的重要机会。现有文献利用聚类算法来理解建筑物的电力需求动态,以分析其负荷行为的差异。这些技术在单一建筑环境中表现良好,但在理解建筑群的需求动态,特别是在峰值负荷期间,存在不足。本文提出了一种面向云计算的基于分位数的数据分析框架,专门设计用于同时评估IBC内多个建筑的需求特征。该框架采用了基于分位数的度量方法,包括风险价值(Value-at-Risk)、条件风险价值(Conditional Value-at-Risk)和条件风险价值标准差,以理解电力波动并量化每栋建筑在校园范围内峰值需求期间的电力影响。通过线性排名比较建筑物,建立了跨建筑比较,依据两个关键标准进行排序:(i)需求波动频繁的建筑物和(ii)对总体IBC需求施加较大电力影响的建筑物。两个标准在排名时权重相等,以识别在峰值负荷期间最低效的建筑物。该框架在加拿大的一所大学中实施,通过重新调试和改造低效建筑,实现了50 MW的显著需求减少。

The spatio-temporal trade-off between ecosystem and basic public services and the urbanization driving force in the rapidly urbanizing region

生态系统与基础公共服务之间的时空权衡以及在快速城市化区域中的城市化驱动因素


【摘要】

With continuous urbanization and population growth, the socio-ecological demands of urban and rural residents have been increasingly intensive and diverse. Such demands need to be met by the ecosystem service (ES) provided by natural capital and the basic public service (BPS) provided by social capital together. However, the ES-BPS trade-off and the driving forces have not been fully revealed, which hinders the synergetic management of the ES and BPS. Therefore, we took the Middle and Lower Reach of the Yangtze River Economic Belt, one of the regions undergoing rapid urbanization in China, as the case study area, and explored the spatio-temporal ES-BPS trade-off and the urbanization driving forces during 2005 to 2019. We first quantified and mapped multiple ESs and BPSs, and then quantified the ES-BPS trade-off over the study period. Finally, we used geographically weighted regression model to reveal how three urbanization features (land, population, and economic urbanization) influenced the ES-BPS trade-off. We found that each ES and BPS, and the comprehensive ES and BPS (the overall capacity to provide multiple ESs and BPSs separately) all exhibited uneven spatial distributions. Results indicated that most eastern prefectures showed decreases in the comprehensive ES but great increases in the comprehensive BPS. Moreover, the ES-BPS trade-off in 2005 exhibited a pattern where the values were high in the south but low in the north, while such an interregional difference was weakened by 2019. From 2005 to 2019, the hotspots of ES-BPS trade-off changes appeared in Shanghai municipality and its surrounding areas, while the coldspots were mainly located in the southern part of Zhejiang Province. Although the influence degree of the three urbanization features on the ES-BPS trade-off spatially varied, population and economic urbanization continuously mitigated the ES-BPS trade-off but land urbanization exacerbated the trade-offs for the whole region. Overall, our study can contribute to the understanding of the ES-BPS relationship and its driving forces, which can support synergetic ES-BPS management in regions undergoing rapid urbanization.

随着城市化和人口增长的持续推进,城市和农村居民的社会生态需求变得越来越强烈和多样化。这些需求需要通过自然资本提供的生态系统服务(ES)和社会资本提供的基本公共服务(BPS)共同满足。然而,生态系统服务与基本公共服务之间的权衡及其驱动因素尚未完全揭示,这阻碍了对生态系统服务和基本公共服务的协同管理。因此,我们以中国快速城市化的区域之一——长江经济带中下游地区为案例研究区域,探讨了2005年至2019年期间的时空生态系统服务与基本公共服务之间的权衡及城市化驱动因素。我们首先量化并绘制了多个生态系统服务和基本公共服务的地图,然后量化了研究期间生态系统服务与基本公共服务之间的权衡。最后,我们使用地理加权回归模型揭示了三种城市化特征(土地、人口和经济城市化)如何影响生态系统服务与基本公共服务之间的权衡。我们发现,每种生态系统服务和基本公共服务,以及综合生态系统服务和基本公共服务(提供多个生态系统服务和基本公共服务的整体能力),都表现出不均匀的空间分布。结果表明,大多数东部地区的综合生态系统服务减少,但综合基本公共服务大幅增加。此外,2005年的生态系统服务与基本公共服务的权衡显示出南部值较高、北部值较低的模式,而到2019年,这种区域间差异有所减弱。从2005年到2019年,生态系统服务与基本公共服务权衡变化的热点出现在上海市及其周边地区,而冷点主要集中在浙江省南部。虽然三种城市化特征对生态系统服务与基本公共服务权衡的影响程度在空间上有所不同,但人口和经济城市化持续减轻了生态系统服务与基本公共服务的权衡,而土地城市化则加剧了整体区域的权衡。总体而言,我们的研究有助于理解生态系统服务与基本公共服务之间的关系及其驱动因素,这可以支持在快速城市化区域内的协同管理。

Spatiotemporal variation and evolutionary analysis of the coupling coordination between urban social-economic development and ecological environments in the Yangtze River Delta cities

长江三角洲城市社会经济发展与生态环境之间耦合协调的时空变化与演变分析


【摘要】

When the process of urbanization has brought economic benefits in Yangtze River Economic Belt (YREB), the environmental issues become increasingly prominent. The evolutionary coupled coordination degree (CCD) between urban social economy and ecological environments was explored in 41 cities of YREB. Results indicated that the overall CCD between urban social economy and ecological environments showed a fluctuating upward trend from 2010 to 2020 in YREB. The CCD of Shanghai was the best among these of 41 cities, while those of three provinces were lower than the average CCD of YREB. There were significant differentiated spatial clusters of high and low among these YREB cities in both the global and local spatial autocorrelation analyses during 2010–2020. The CCD estimations indicated a fitted spatial distribution of "high in the east and low in the west" in YREB. Furthermore, CCD was positively influenced by the urban density of population, economic acceleration and technical advancement (P < 0.01), while it was negatively influenced by the urban industrial structures and energy consumption (P < 0.01). Subsequently, corresponding policy implications and recommendations, including enhancing policy innovation and promoting technological progress, were proposed to facilitate the formulation of evidence-based developmental strategies and policies of sustainable cities and society in YREB.

随着长江经济带(YREB)的城市化进程带来经济利益,环境问题也变得越来越突出。本文探讨了长江经济带41个城市中城市社会经济与生态环境之间的演变耦合协调度(CCD)。结果表明,2010年至2020年间,长江经济带城市社会经济与生态环境之间的整体CCD呈现波动上升趋势。上海的CCD在这41个城市中表现最好,而三个省份的CCD低于长江经济带的平均水平。在2010年至2020年期间,这些城市在全球和地方空间自相关分析中均存在显著的高低差异空间聚类。CCD的估算结果表明,长江经济带的空间分布呈现出“东部高、西部低”的趋势。此外,CCD受到人口城市密度、经济加速和技术进步的正面影响(P < 0.01),而受到城市工业结构和能源消费的负面影响(P < 0.01)。随后,提出了相应的政策建议,包括加强政策创新和促进技术进步,以助力长江经济带可持续城市和社会的发展策略与政策的制定。

A review of evolving climate and energy economy trends to enhance the dynamic life cycle assessment of buildings

增强建筑动态生命周期评估的气候和能源经济趋势综述


【摘要】

The changing global climate is impacting life cycle effects of all sectors, including the building sector. To effectively decrease the construction sector's 40 % share of global annual energy use and carbon emissions, it's crucial to integrate these changes into life cycle assessments (LCA) to inform current and future energy policies, since buildings have lifespans exceeding 100 years. Current research lacks methods and data to embed future weather and energy shifts into LCA. This paper quantifies these future changes and discusses their integration into building LCA. Using industry reports and scholarly articles, we calculated global energy trends and weather patterns for 2030, 2050, and 2080. The projected energy use changes across United States economic sectors were also analyzed. Projections indicate a 41–59 % decline in fossil fuel use by 2050, with renewable energy increasing from 11 % to 41 %. Concurrently, global temperatures may rise by 2–5 °C, signaling major weather shifts. These shifts will translate into an economy-wide energy intensity decrease, showing an expected drop of 8 %. A Dynamic LCA (DLCA) framework is also discussed to include these shifts into LCA, to help not only researchers and practitioners involved in the LCA of buildings but also energy policy makers in effectively mitigating climate change.

全球气候变化正在影响所有领域的生命周期效应,包括建筑部门。为了有效减少建筑部门在全球年度能源使用和碳排放中占据的40%份额,将这些变化整合到生命周期评估(LCA)中至关重要,以指导当前和未来的能源政策,因为建筑物的使用寿命超过100年。目前的研究缺乏将未来气候和能源变化嵌入LCA的方法和数据。本文量化了这些未来变化,并讨论了如何将其整合到建筑LCA中。通过使用行业报告和学术文章,我们计算了2030年、2050年和2080年的全球能源趋势和气候模式。还分析了美国经济部门的能源使用变化预测。预测表明,到2050年,化石燃料使用将下降41%到59%,可再生能源的比例将从11%增加到41%。与此同时,全球气温可能上升2到5°C,预示着主要的天气变化。这些变化将转化为经济整体能源强度的降低,预计下降8%。还讨论了一个动态生命周期评估(DLCA)框架,以将这些变化纳入LCA中,帮助从事建筑LCA的研究人员和实践者,以及能源政策制定者有效地应对气候变化。

Developing thermal prediction models for children in outdoor environments

为户外环境中的儿童开发热预测模型


【摘要】

How children experience warm and hot climates differs from adults, yet most models of thermal responses to the environment are based on adults. We modeled the thermal physiological characteristics of 162 healthy children, ages of 7–14 under light, moderate, and vigorous intensity activities and thermal transitions (alternate movement under sunlight and shade). Subsequently, we built an accurate and rapid prediction model for children's thermal sensation based on relationships between their outdoor thermal physiology and thermal sensation. The range and mean absolute change in rate of skin temperatures were greatest at wrist and lower leg in different stages. These two temperatures best reflected the transient change in thermal environment. At three activity levels and five thermal transitions, the wrist and lower leg skin temperatures were significantly correlated with thermal sensation (P < 0.05). Heart rate (HR) was significantly correlated with thermal sensation only during vigorous intensity activities (P < 0.05). A light and moderate intensity activity model (DTS-kid (LM)) (accuracy: 85.9 %) was built based on the wrist skin temperature (Twrist) and its change rate, and a vigorous intensity activity model (DTS-kid (V)) (accuracy: 83.9 %) was built based on HR, Twrist and the change rate of Twrist.

儿童对温暖和炎热气候的体验与成人有所不同,但大多数热响应模型都是基于成人的。我们对162名健康儿童(年龄在7至14岁)进行了建模,研究了他们在轻度、中等强度和剧烈活动下的热生理特征以及热过渡(在阳光下和阴影下交替活动)。随后,我们建立了一个准确且快速的儿童热感觉预测模型,基于他们的户外热生理学与热感觉之间的关系。不同阶段皮肤温度的范围和平均绝对变化率在手腕和小腿部位最大。这两个部位的温度最好地反映了热环境的瞬时变化。在三种活动水平和五种热过渡条件下,手腕和小腿部皮肤温度与热感觉显著相关(P < 0.05)。心率(HR)仅在剧烈活动期间与热感觉显著相关(P < 0.05)。我们基于手腕皮肤温度(Twrist)及其变化率建立了一个轻度和中等强度活动模型(DTS-kid (LM),准确率:85.9%),并基于HR、Twrist及其变化率建立了一个剧烈活动模型(DTS-kid (V),准确率:83.9%)。

Towards sustainable smart cities: Integration of home energy management system for efficient energy utilization

迈向可持续智能城市:家庭能源管理系统的集成以提高能源利用效率


【摘要】

Smart Homes (SHs) play a crucial role in the broader context of smart cities, contributing to the overall efficiency, sustainability, and quality of life for residents. This work presents a computationally efficient mathematical model for Home Energy Management Systems (HEMS) to activate the Demand Side Management (DSM) while minimizing the energy consumption costs of SHs. The proposed model is represented as a standard Mixed-Integer Linear Programming (MILP) optimization problem. The proposed HEMS provides the optimal scheduling of home appliances and plugging time for charging Electric Vehicles (EV) at home. The main objective of this optimization problem is to minimize the electricity bills while improving the load profile of the distribution system in the context of smart cities. In this study, load management for a typical household has been studied considering several electricity tariffs in Portugal. The simulation results confirm that in the presence of the proposed HEMS, the electricity bill will be effectively reduced while consumer behavior is changed. The cost savings that can be attained through only shifting loads is 5.7 %, while it can reach 67.65 % by installing a hybrid energy system at the studied smart home. The weekly cost reduction percentage due to charging the EV at home is around 16.24 % compared to charging the EV using public charging stations regardless of the traveling time and waiting at the public charging stations.

智能家居(SHs)在智能城市的整体框架中扮演着至关重要的角色,提升了居民的整体效率、可持续性和生活质量。本研究提出了一种计算效率高的数学模型,用于家庭能源管理系统(HEMS),以激活需求侧管理(DSM)并最小化智能家居的能源消耗成本。该模型被表示为标准的混合整数线性规划(MILP)优化问题。提出的HEMS提供了家用电器的最佳调度和电动汽车(EV)在家充电的最佳时间。此优化问题的主要目标是减少电费,同时改善智能城市背景下配电系统的负荷曲线。在本研究中,考虑了葡萄牙的多种电价,对典型家庭的负荷管理进行了研究。模拟结果确认,在所提出的HEMS的支持下,电费将有效减少,同时消费者行为也会发生变化。仅通过负荷转移可以实现5.7%的成本节省,而在研究的智能家居中安装混合能源系统则可以达到67.65%的节省。由于在家充电电动汽车,周成本减少的百分比约为16.24%,相比于使用公共充电站充电,不论是旅行时间还是等待公共充电站的时间。

Comparative simulation of transpiration and cooling impacts by porous canopies of shrubs and trees

多孔冠层对灌木和树木的蒸腾和冷却影响的比较模拟


【摘要】

Vegetation cooling effects can effectively improve the outdoor microclimate. To explore the potential of vegetation transpiration cooling, we validated the feasibility of a new coupled porous medium and solar radiation model to simulate the interactions between vegetation transpiration and other physical processes in CFD. To emphasize the spatial extent of vegetation's influence, we compared and quantified the flow-adjustment distances(LFA) for wind speed, the temperature difference between simulated temperature and background temperature(ΔT(°C)), and water vapor mass fraction(ΔMw(g/kg)) between shrub(100m) and tree(200m) canopies: 1)For both vegetations, the LFA required for ΔT and ΔMw exceeds that of wind speed achieve fully-developed, indicating the momentum adjustment occurs more rapidly than energy and mass transport processes. 2)Vegetation drag effect depends on both leaf area density and vegetation canopy's height and width.3)Vegetation exhibits a significantly higher transpiration cooling effect under ambient relative humidity(RH)=0% than RH=60%(the mean value of ΔT, ΔTfd), for the tree(z=1.5m): ΔT fd is -5.4°C (-1.4∼-1.5°C) at RH=0%/60%. 4)At RH=60%, both shrubs and trees exhibit a notable warming phenomenon near the vegetation canopies tops(ΔTMax=1.3°C/0.9°C for shrubs/trees). This study provides and confirms a reliable numerical method for simulating the interactions of vegetation transpiration and other physical processes in urban or rural areas.

植物的降温效应可以有效改善户外微气候。为了探讨植物蒸腾降温的潜力,我们验证了一种新型的耦合多孔介质和太阳辐射模型在计算流体力学(CFD)中模拟植物蒸腾与其他物理过程之间相互作用的可行性。为了强调植物影响的空间范围,我们比较并量化了灌木(100米)和树木(200米)冠层在风速、模拟温度与背景温度之间的温度差(ΔT(°C))以及水蒸气质量分数(ΔMw(g/kg))的流动调整距离(LFA):1)对于这两种植被,ΔT和ΔMw所需的LFA超出了风速达到充分发展的范围,这表明动量调整比能量和质量传输过程发生得更快。2)植物的阻力效应依赖于叶面积密度以及植被冠层的高度和宽度。3)在环境相对湿度(RH)为0%时,植物表现出显著高于RH为60%时的蒸腾降温效应(树木z=1.5m时ΔTfd在RH为0%/60%下分别为-5.4°C/-1.4∼-1.5°C)。4)在RH为60%时,灌木和树木冠层顶部附近均出现显著的升温现象(灌木/树木的ΔTMax分别为1.3°C/0.9°C)。本研究提供并验证了一种可靠的数值方法,用于模拟城市或乡村地区植物蒸腾与其他物理过程之间的相互作用。

The time-advance effect of China's rooftop solar photovoltaics program on the dual carbon targets and its implication on the globe

中国屋顶太阳能光伏项目对双碳目标的时间推进效应及其全球影响


【摘要】

Rooftop solar photovoltaics (RSPV) plays an important role in energy transition and climate goals. However, the contribution of RSPV to the dual carbon targets (DCTs) has not yet been quantitatively investigated at the national or global scale. Here, we investigate this contribution with an improved Stochastic Impacts by Regression on the Population, Affluence, and Technology (STIRPAT) model. We find out the time-advance effect of China's pilot RSPV program, i.e., doubling expansion of the current pilot area helps that the DCTs will be achieved 5 years ahead of schedule; a full expansion plan from merely six identified key provinces can be enough to guarantee that China will achieve carbon peak and carbon neutrality 5 and 4 years ahead of their respective time schedules. This effect implies global RSPV development; about 25 % of the world's buildable rooftops for RSPV installation will help reduce 1.4 billion tons of carbon emissions per year and thus achieve global carbon neutrality by 2050. The results will attract a widespread new energy community interested in expanding RSPV and helping governments formulate carbon reduction policies.

屋顶太阳能光伏(RSPV)在能源转型和气候目标中扮演着重要角色。然而,RSPV 对双碳目标(DCTs)的贡献在国家或全球范围内尚未进行定量研究。在此,我们通过改进的回归随机影响模型(STIRPAT)来研究这一贡献。研究发现,中国试点 RSPV 计划的时间提前效应,即当前试点区域的扩展加倍可以使双碳目标提前 5 年实现;从仅六个关键省份的全面扩展计划可以确保中国在各自时间表前 5 年和 4 年实现碳达峰和碳中和。这一效应暗示了全球 RSPV 发展;全球约 25% 的可建造屋顶用于 RSPV 安装将有助于每年减少 14 亿吨碳排放,从而在 2050 年实现全球碳中和。这些结果将吸引广泛的新兴能源社区,关注扩大 RSPV并帮助政府制定减排政策。

Bridging chance-constrained and stochastic optimization for risk estimation of virtual energy hubs dominated by hybrid vehicles under diverse uncertainties: To improve economic sustainability

弥合机会约束优化与随机优化:在多种不确定性下对由混合动力车辆主导的虚拟能源中心进行风险估计以提高经济可持续性


【摘要】

Virtual energy hubs (VRHBs) combine dispersed energy resources to enhance the efficient use of various energy sources, grid flexibility, and renewable energy adoption. This paper investigates the adoption of VRHBs with power-to-gas (P2G) facilities and hybrid electric-compressed natural gas vehicles (HNGEVs) in the presence of renewable resources to effectively tackle carbon emissions and increase the flexibility of VRHBs. The proposed P2G facility is constructed from carbon capture to collect carbon pollution from fossil fuel resources and HNGEVs to recycle into synthesis gas in a methanation plant. Furthermore, due to severe uncertainties due to renewable resources and energy consumption intensity, the proposed framework utilizes stochastic-driven chance-constrained optimization, which enables decision-makers in VRHBs to account for the probabilistic nature of uncertainties. Chance-constrained optimization explicitly considers uncertainty through probabilistic constraints, providing a more robust and reliable solution compared to deterministic methods. By modeling uncertainties using chance-constrained programming, VRHBs can manage the economic risks under unexpected worst realizations in uncertainties. Based on the results, the P2G facility leads to a significant reduction in the daily emissions by 63.06 % and 42.77 % observed under no-risk and full-risk conditions, respectively. In addition, the suggested chance-constrained method resulted in a major decrease of 69 % in overall operational costs.

虚拟能源枢纽(VRHBs)结合了分散的能源资源,以提高各种能源的使用效率、电网灵活性和可再生能源的采纳。本文研究了在可再生资源的背景下,采用带有气体转化(P2G)设施和混合电动-压缩天然气车辆(HNGEVs)的VRHBs,以有效应对碳排放并提高VRHBs的灵活性。所提出的P2G设施由碳捕集构建,用于从化石燃料资源中收集碳污染,并通过HNGEVs回收至甲烷化厂中的合成气。此外,由于可再生资源和能源消耗强度的严重不确定性,所提出的框架利用了随机驱动的机会约束优化,使VRHBs的决策者能够考虑不确定性的概率特征。机会约束优化通过概率约束显式地考虑不确定性,与确定性方法相比,提供了更稳健和可靠的解决方案。通过使用机会约束编程对不确定性进行建模,VRHBs可以在不确定性意外最坏情况下管理经济风险。基于结果,P2G设施在无风险和全风险条件下分别使每日排放减少了63.06%和42.77%。此外,建议的机会约束方法使整体运营成本减少了69%。

Understanding the role of urban features in land surface temperature at the block scale: A diurnal cycle perspective

理解城市特征在块尺度土地表面温度中的作用:从日循环的角度


【摘要】

The diverse urban features considerably influence land surface temperature (LST). Numerous studies have extensively investigated the impacts of 2D/3D urban features on LST. However, the diurnal impacts have not been comprehensively understood. Therefore, taking 1, 510 blocks within the 4th ring road of Beijing as samples, this study examined the influence of urban features (2D: low vegetation, water, and impervious surface; 3D: buildings and trees) on diurnal LST at the block scale based on ECOSTRESS LST using boosted regression tree (BRT) algorithm. The results showed that trees exhibit better cooling effects than low vegetation except at 3:09. The 3D features exhibited a greater impact on diurnal LST compared with 2D features, and it contributed strongly to daytime LST, which was 27.8 % on average higher than the 2D features. Building and tree densities had the greatest influence on daytime LST, while building height influenced nighttime LST the most. The impacts of key metrics on diurnal LST were nonlinear, and the relationship had diurnal variations. Taller buildings and trees were negatively correlated with LST during the daytime and transition time, but positively correlated with nighttime LST. The findings provide insights into landscape optimization strategies to improve block thermal comfort.

城市特征对地表温度(LST)的影响十分显著。大量研究已经广泛调查了二维/三维城市特征对LST的影响。然而,日变化影响尚未得到全面理解。因此,本研究以北京市第四环路内的1510个街区为样本,基于ECOSTRESS LST数据,使用提升回归树(BRT)算法考察了城市特征(二维:低植被、水体和不透水表面;三维:建筑物和树木)对街区尺度日变化LST的影响。结果显示,树木的降温效果优于低植被,除非在3:09时刻。三维特征对日变化LST的影响大于二维特征,且对白天气温的贡献显著,平均比二维特征高出27.8%。建筑物和树木密度对白天气温影响最大,而建筑物高度对夜间LST影响最显著。关键指标对日变化LST的影响是非线性的,并且具有日变化特征。高建筑物和树木在白天及过渡时期与LST呈负相关,但在夜间与LST呈正相关。这些发现为改进街区热舒适性的景观优化策略提供了见解。

Future urban ecological land transition and its implications for high-heat exposure in China

未来城市生态土地转变及其对中国高热暴露的影响


【摘要】

Urban ecological land (UEL) is an important nature-based solution for mitigating human exposure to extreme heat (i.e., high-heat exposure, HHE), but the impacts of future UEL transition remain unclear. This study developed a high spatial-temporal resolution dataset (30 m) of urban land cover in China during the 21st century under the shared socioeconomic pathway and the representative concentration pathway (SSP-RCP) to quantify the contribution of UEL transition to HHE. Results showed that UEL transitions will influence 0.12–0.26 °C of the HHE from 2021 to 2100 and is the dominant driver in 10.2–22.8 % of cities (including 95.1 million to 181.2 million people in 2100), with substantial regional disparities. Moreover, UEL landscape pattern is a more important factor than area. Specifically, the UEL evolution pattern will dominate the exposure of 8.02 to 10.77 million people to extreme heat within the urban cores (i.e., predominant urban areas) in the SSP1-2.6 and SSP2-4.5 scenarios, especially in the eastern cities. Under the SSP3-7.0 and SSP5-8.5 scenarios, the UEL evolution pattern will dominate the exposure of 2.44 to 5.34 million people to extreme heat on the expansion surfaces (i.e., areas transitioning from rural to urban), especially in the western cities. The optimization of UEL landscape patterns should be a top priority as an urban heat adaptation strategy to maximize urban resilience to climate change.

城市生态用地(UEL)是一种重要的基于自然的解决方案,用于减轻人类对极端高温(即高温暴露,HHE)的影响,但未来UEL转型的影响仍不明确。本研究开发了一个具有高空间-时间分辨率的数据集(30米),用于量化21世纪中国城市土地覆盖下的UEL转型对HHE的贡献。结果显示,从2021年到2100年,UEL转型将影响0.12–0.26°C的HHE,并且在10.2–22.8%的城市中(包括2100年9501万人到1.812亿人),UEL转型是主要驱动因素,且存在显著的区域差异。此外,UEL景观模式比面积更为重要。具体而言,在SSP1-2.6和SSP2-4.5情景下,UEL演变模式将主导820万到1077万人在城市核心区(即主要城市区域)暴露于极端高温,尤其是在东部城市。在SSP3-7.0和SSP5-8.5情景下,UEL演变模式将主导244万到534万人在扩展表面(即从乡村到城市的过渡区域)暴露于极端高温,尤其是在西部城市。优化UEL景观模式应作为城市热适应策略的首要任务,以最大化城市对气候变化的韧性。

Optimal sizing of PV–Wind generators with a smart EV charging framework to build grid friendly Net Zero Energy Campus

基于智能电动汽车充电框架的光伏-风力发电机优化配置,以构建电网友好的净零校园


【摘要】

Electric Vehicles (EVs) are creating a significant challenge on the electric grid as they demand huge amounts of power for their charging. On-site power generation through renewable energy sources (RES) is one of the viable approaches to meet the demands of EVs and other loads of a campus. Hence, an optimal sizing of a hybrid PV–Wind system is considered in this work to build a Net Zero Energy Campus (NZEC). Generally, EVs are scheduled after obtaining the size of RES through a sizing procedure. As a unique approach of this work, a smart EV charging framework is developed to model the profile of EV charging demand and this modeled load profile of EV is considered along with the local load profile of the campus for optimal sizing procedure. The size of PV–Wind sources are optimized by minimizing three objective functions such as the annual operating cost of the system (AOC), loss of power supply probability (LPSP) and total energy transfer (TET). The optimization is carried out by Non-Dominated Sorting Genetic Algorithm II (NSGA II). The maximum utilization of RES and the reduced grid congestion attained through the proposed sizing approach showcase the grid friendliness of the designed NZEC.

电动汽车(EVs)对电网提出了重大挑战,因为它们在充电时需要大量电力。通过可再生能源(RES)进行现场发电是满足电动汽车和校园其他负荷需求的可行方法之一。因此,本研究考虑了混合光伏-风能系统的最佳规模,以建立零能耗校园(NZEC)。通常,在确定了可再生能源系统的规模后,电动汽车的调度才会进行。本研究独特的方法是开发了一个智能电动汽车充电框架,用于模拟电动汽车充电需求的曲线,并将这个模拟的负荷曲线与校园的本地负荷曲线一起用于最佳规模设计过程。通过最小化三个目标函数,即系统的年运行成本(AOC)、电力供应丧失概率(LPSP)和总能量传输(TET),来优化光伏-风能资源的规模。优化采用了非支配排序遗传算法 II(NSGA II)。通过所提出的规模设计方法实现了可再生能源的最大利用和减少的电网拥堵,展示了所设计的零能耗校园的电网友好性。

Sustainability assessment of cities using multicriteria decision-making combined with deep learning methods

使用多标准决策方法结合深度学习方法对城市进行可持续性评估


【摘要】

City sustainability is integral to the Sustainable Development Goals for 2030 of the United Nations, and precise assessments are required to inform effective development strategies. However, the assessment of city sustainability is complicated by the conflict and interaction of multiple factors. In this study, we developed a comprehensive model within the triple bottom line (TBL) framework to evaluate the sustainable development performance of 16 cities in Shandong Province, China. Firstly, we integrated spatial-temporal graph convolutional networks combined with long short-term memory (ST-GCN-LSTM) networks to forecast indicator data across economic, social, and environmental dimensions. Secondly, we employed hybrid multicriteria decision-making (MCDM) analysis to evaluate city sustainability performance. Finally, we conducted case studies on the cities of Jinan and Binzhou, proposing targeted improvement strategies based on the influence network relationship map (INRM). The modified Vlse kriterijumska Optimizacija I Kompromisno Resenje (VIKOR) demonstrates that Weihai ranks the highest in terms of sustainability; Jinan should focus on environmental indicators such as green coverage and wastewater management, while Binzhou should prioritize social and environmental factors such as healthcare and social insurance. This study demonstrated that integrating deep learning with MCDM offers a novel and effective approach to city sustainability evaluation.

Experimental implementation of an emission-aware prosumer with online flexibility quantification and provision

具有在线灵活性量化和供应的排放感知产消者者的实验性实施


【摘要】

Active building energy management can facilitate the development of low-carbon buildings and support flexible operations of future smart cities, thanks to advancements in digitalization To fully leverage these benefits, it is essential to integrate diverse objectives and engage multiple stakeholders. However, a gap remains in comprehensive field insights into emission reduction, flexibility provision, and user impacts. This study examined how a real occupied building, with all its energy assets, could function as an emission-aware prosumer with flexible energy consumption. An existing building energy management system was enhanced by integrating a model predictive control strategy. The setup reduced equivalent carbon emissions from electricity imports and provided flexibility to the energy system. The experimental results indicate an emission reduction of 12.5% compared to a rule-based controller that maximized PV self-consumption. In addition, a minimal flexibility provision experiment was demonstrated with a locally emulated distribution system operator. The results suggest that flexibility was provided without the risk of rebound effects, as flexibility was quantified and communicated to the system operator in advance. This study demonstrates the feasibility of low-carbon buildings and their support for flexible energy systems, while also identifying and discussing practical scalability challenges.

主动建筑能源管理能够促进低碳建筑的发展,并支持未来智能城市的灵活操作,这得益于数字化的进步。为了充分利用这些优势,必须整合多样化的目标,并参与多个利益相关者。然而,对于减排、灵活性提供和用户影响的综合实地见解仍存在缺口。本研究考察了一个实际使用的建筑如何在具备所有能源资产的情况下,作为一个注重排放的生产者与消费者,进行灵活的能源消费。通过集成模型预测控制策略,增强了现有的建筑能源管理系统。该设置减少了来自电力进口的等效碳排放,并为能源系统提供了灵活性。实验结果表明,与最大化光伏自用的基于规则的控制器相比,碳排放减少了12.5%。此外,还进行了一个最小化灵活性提供实验,与一个本地仿真的配电系统运营商进行了演示。结果表明,在灵活性量化并提前传达给系统运营商的情况下,灵活性提供的过程中没有出现反弹效应的风险。本研究展示了低碳建筑的可行性及其对灵活能源系统的支持,同时也识别并讨论了实际可扩展性挑战。

Investigating the effect of lower body local radiant warming on occupant thermal comfort in battery electric vehicles during cold conditions

在寒冷条件下,降低身体局部辐射加热对电池电动汽车乘员热舒适性的影响


【摘要】

The wintertime decrease in the driving range of battery electric vehicles (BEVs), partially attributed to cabin heating with improper setpoints, necessitates the improvement of occupant thermal comfort with reduced energy consumption. While local warming shows promise, understanding its impact on occupant comfort with thermal transients from cabin heating, ventilation, and air conditioning (HVAC) is limited. To address this gap, we investigated thermal perception in twenty-five participants under three distinct warming modes within BEVs operating through typical winter conditions: HVAC alone, HVAC with continuous lower body local radiant warming (LRW), and HVAC with periodic lower body LRW. Results show that the rapid change in skin temperature from lower body local warming does not immediately improve comfort. While a significant improvement in comfort (p < 0.05) is observed with lower body warming, it becomes evident only when the cabin transients subside. Consequently, we propose a framework that advocates for reducing HVAC setpoint and control of LRW of the lower body based on occupant preferences. Our feasibility study demonstrates a 45.3 % reduction in energy consumption by reducing the HVAC setpoint from 25 to 18 °C. These findings enhance the prospects for efficient thermal comfort management in BEVs.

冬季,电池电动汽车(BEVs)的续航里程减少部分归因于车厢加热设置不当,因此需要在减少能量消耗的同时改善乘员的热舒适度。虽然局部加热显示出一定的潜力,但对其在车厢加热、通风和空调(HVAC)过程中热瞬态下对乘员舒适度的影响了解有限。为了解决这一问题,我们研究了在典型冬季条件下,二十五名参与者在三种不同加热模式下的热感知:仅HVAC、HVAC加持续下半身局部辐射加热(LRW)、HVAC加间歇性下半身LRW。结果显示,下半身局部加热带来的皮肤温度快速变化并不会立即改善舒适度。虽然下半身加热在舒适度上有显著改善(p < 0.05),但这种改善仅在车厢热瞬态消退后才显现。因此,我们提出了一种框架,建议根据乘员的偏好降低HVAC设定点并控制下半身LRW。我们的可行性研究表明,通过将HVAC设定点从25°C降低到18°C,可实现45.3%的能量消耗减少。这些发现提高了在BEVs中高效管理热舒适度的前景。

The influence of regional industrial structure on the suitability of biomass energy development: A case study of 30 counties and cities in a cold region of China

区域产业结构对生物质能源开发适宜性的影响:以中国寒冷地区30个县市为例


【摘要】

The development of the biomass economy contributes to economic growth and social development. The study of biomass energy economy from the perspective of industrial structure type has the significance of promoting the optimization and upgrading of industrial structure, promoting the development of green industry and other aspects. It helps to promote the sustainable development of the economy and society. And industrial structure is a major component of the socio-economic system. Therefore, it is necessary to study the impact of material energy supply and demand from the perspective of regional industrial structure type. The objective of this study is to explore the relationship between the type of industrial structure and the development of biomass energy from the perspective of the economic direction, so as to fill the gap in this research perspective. Based on the three major industries generally regarded to constitute GDP - agriculture, industry, and service - the regression results of STATA software were used to calculate biomass potential according to crop distribution status. Using the ArcGIS analysis tool, the biomass break-even model related to resource supply-demand has been used to obtain the break-even status of the research area under six industrial structures in the past 20 years. According to research results, the break-even degree of biomass energy supply is between 0.109 and 1.236 when the industrial structure types of counties and cities are service-agriculture-industry and industry-agriculture-service. This is suitable for biomass energy development. When the industrial structure type of counties and cities is service-industry-agriculture, the break-even degree of biomass energy supply is between -0.428 and 0.277, which is not suitable for biomass energy development.

RETRACTED: Optimizing energy and quantifying dispatchable potential of holistic HVAC systems

撤回:优化能源并量化整体HVAC系统的可调度潜力


【摘要】

The authors reported serious errors in the publication that ultimately rendered the methodology proposed in the paper unreliable. The study configured the HVAC system with different numbers of air handling units, and the results are shown in Fig. 12. However, by comparing the results obtained from the qualitative analysis with those obtained in Fig. 12, it is found that there is a great contradiction between the two. Therefore, the energy consumption optimization framework and HVAC configuration method adopted by the research institute are unreliable. Also since the object of this paper is office buildings, the various parameters of the air-side economizers in the AHUs configured in office buildings are derived from the data in the air-side economizers configured in the data center.Therefore, the Authors requested retraction and the Editor agreed with this request. The Authors regret the errors.

The impact of innovative human capital agglomeration on urban green development efficiency: Based on panel data of 278 Cities in China

创新人力资本聚集对城市绿色发展效率的影响:基于中国278个城市的面板数据


【摘要】

As a scarce and high-quality production factor, innovative human capital (IHC) significantly contributes to the innovation-driven development and low-carbon transformation of economies. Based on panel data of 278 cities in China spanning from 2011 to 2021, this paper employs Super-SBM DEA method, two-stage systematic GMM, and dynamic panel threshold model to comprehensively study the effect of innovative human capital agglomeration (IHCA) on urban green development efficiency (UGDE). The results indicate that: (1) In general, there exists an inverted U-shaped relationship between IHCA and UGDE. The Williamson hypothesis significantly influences the green development process of Chinese cities. (2) The inflection values of the inverted U-shaped curve are sensitive to different factors. Environmental regulations push back the threshold of optimal agglomeration size for IHCA, reducing the risk of the "crowding effect". (3) The digital economy has a positive moderating effect on the impact of IHCA on UGDE. The moderating effect of industrial digitization is more significant than that of digital industrialization. This paper puts forward suggestions on rational utilization of positive externalities of IHCA, appropriate enhancement of environmental regulation, and promotion if the integration of innovative talents with the digital economy.

Novel energy management options for charging stations of electric vehicles in buildings without increasing peak demand for sustainable cities

在不增加峰值需求的情况下,为建筑中的电动汽车充电站提供新型能源管理选项,以实现可持续城市


【摘要】

Electric vehicles are recognised as a critical step in making the transportation sector more environmentally friendly, especially when powered by renewable energy sources. A major hindrance to their widespread adoption is the scarcity of charging stations and the absence of grid access. This study explores and examines four distinct ways to enhance the energy grid of buildings. The primary goal of these solutions is to generate more capacity without raising the peak electricity load of the building through the incorporation of energy storage technologies. The target location is Southern Ontario, Canada, which is one of most populated regions in Canada. Strategy 3 stands out as the most promising alternative, with an impressive 35 % increase in charging station capacity compared to other strategies. Using this method, it is feasible to store 353.4 GWh of energy during the summer and 480.1 GWh during the winter. In summer, the station can release 243.1 GWh, and in the winter, 345.6 GWh of energy can be efficiently used to charge electric vehicles. Strategy 4, which includes hydrogen generation and fuel cell systems, offers a competitive alternative with a 28 % increase in capacity. This method allows for charging station capabilities of 52 GW during the summer and 13 GW during the winter. The strategies emphasize the importance of adaptable capacity solutions to address variations in demand on a seasonal and daily basis while considering both economic and environmental sustainability. As the adoption of electric vehicles continues to rise, the nuanced operational aspects of these strategies are pivotal for the development of sustainable and efficient transportation ecosystems, ensuring that electric vehicle charging infrastructure keeps pace with the growing demand.

Optimizing smart grid performance: A stochastic approach to renewable energy integration

优化智能电网性能:可再生能源集成的随机方法


【摘要】

Smart grids offer numerous possibilities for developing and executing sustainable and efficient electricity supply chains that exhibit increased resilience to disturbances. The exploration of the Electric Supply Chain Network (ESCND) design problem using smart grids has been limited. This article aims to tackle this challenge through the application of a robust multi-objective optimization approach, encompassing three economic goals (maximizing profit), environmental goals (minimizing greenhouse gas emissions), and resilience goals (maximizing network resilience). Additionally, the optimization process takes into account the dual objectives of maximizing efficiency and minimizing energy loss by incorporating relevant cost considerations. The proposed methodology incorporates distinctive features of smart grids, such as demandside management programs, microgrid structures, bidirectional distribution lines, and consumer–supplier nodes. It addresses various interconnected decisions, including location placement, capacity expansion, load allocation, and pricing. To solve the formulated model, a potent combination of multi-objective optimization methods based on cutting-plane algorithms and AUGMECON2 is introduced. Subsequently, the proposed model and solution approach are applied to a practical case study, and the obtained results are comprehensively examined. The findings suggest that, despite potential contradictions between economic and environmental objectives, the implementation of smart grids can concurrently improve environmental performance and network flexibility.

智能电网为开发和实施可持续高效的电力供应链提供了许多可能性,且这些供应链具有更高的抗干扰能力。对使用智能电网的电力供应链网络(ESCND)设计问题的探索尚有限。本文旨在通过应用一种鲁棒的多目标优化方法来解决这一挑战,该方法涵盖了三个经济目标(最大化利润)、环境目标(最小化温室气体排放)和韧性目标(最大化网络韧性)。此外,优化过程还考虑了通过相关成本考虑来最大化效率和最小化能源损耗的双重目标。所提出的方法论结合了智能电网的独特特征,如需求侧管理程序、微电网结构、双向配电线路和消费者-供应商节点。它涉及到位置选择、容量扩展、负荷分配和定价等各种互相关联的决策。为解决所构建的模型,引入了一种基于切平面算法和AUGMECON2的强大多目标优化方法。随后,将该模型和解决方案应用于实际案例研究中,并对获得的结果进行了全面的检验。研究结果表明,尽管经济和环境目标之间可能存在潜在矛盾,但智能电网的实施可以同时改善环境表现和网络灵活性。

Urban energy transition in renewable energy management considering policy and law challenges and opportunities in the pursuit of clean and sustainable urban environments

考虑政策和法律挑战与机遇的可再生能源管理中的城市能源转型:追求清洁和可持续城市环境


【摘要】

This research presents a novel approach to enhance sustainable energy development based on wind turbine (WT) output power prediction through the development of a hybrid deep learning model, considering policy and law challenges associated with the problem. The proposed model integrates a Self-Supervised Generative Adversarial Network (GAN) with Attention-based Recurrent Neural Networks (RNNs). The Self-Supervised GAN contributes to improved feature representation learning, while Attention-based RNNs capture temporal dependencies for accurate WT output power forecasting considering political challenges. Additionally, a Modified Adaptive Flower Pollination Algorithm (AFPA) is introduced to optimize the selection of the GAN model structure in view of the legal and political objectives. This adaptive approach refines the architecture of the GAN, enhancing its ability to generate realistic and informative features for the subsequent Attention-based RNNs. The efficacy of the hybrid model is demonstrated through real-world applications in an urban area, emphasizing sensitivity and stability analyses. A thorough investigation into the sensitivity of key model parameters, including the number of hidden units in the Attention-based RNNs and GAN structures, is conducted to fine-tune the model's performance. Stability analysis is employed to assess the robustness of the proposed method under dynamic conditions, ensuring its reliability in practical scenarios. Results indicate that the hybrid model, guided by the Modified AFPA, outperforms existing approaches in WT output power prediction.

这项研究提出了一种新颖的方法,通过开发混合深度学习模型来提高风力涡轮机(WT)输出功率预测的可持续能源发展,同时考虑了与此问题相关的政策和法律挑战。该模型将自监督生成对抗网络(GAN)与基于注意力的递归神经网络(RNNs)相结合。自监督GAN有助于改进特征表示学习,而基于注意力的RNNs捕捉时间依赖性,从而准确预测风力涡轮机的输出功率,并考虑政治挑战。此外,还引入了修改的自适应花粉传播算法(AFPA)来优化GAN模型结构的选择,以应对法律和政治目标。这种自适应方法优化了GAN的架构,提高了其生成真实且信息丰富的特征的能力,从而提升了随后的基于注意力的RNNs的性能。通过在城市区域的实际应用中演示了混合模型的有效性,并强调了灵敏度和稳定性分析。对关键模型参数的灵敏度进行了深入调查,包括基于注意力的RNNs和GAN结构中的隐藏单元数量,以微调模型的性能。稳定性分析用于评估所提方法在动态条件下的鲁棒性,确保其在实际场景中的可靠性。结果表明,由修改AFPA指导的混合模型在风力涡轮机输出功率预测方面优于现有方法。所提方法展示了将最先进的深度学习技术与自适应优化算法相结合的重要性,以实现城市能源管理应用中的准确和稳定预测。
