中文简介:
由于人口增长和城市化，城市地区基础设施、服务和个人之间的相互依赖性继续增加。城市地区已经消耗了世界能源的80%，到2050年，预计人口将增长近70%，这将进一步推动能源消耗的增长。因此，我们必须更好地了解人类对建筑能耗的影响在其所在的城市空间背景下的可变性。城市人口的市内旅行是由于个人在不同地点从事活动而进行的。然而，随着时间的推移，人们的日常活动和访问的地点数量会有所不同。在这里，我们研究了两个不同人群（即回返者和探索者）的人类流动网络之间的空间相互依赖性，作为他们日常活动模式的指标，以及天然气消耗量，以探索如何利用人类流动网络的变化来解释能源使用的空间波动。我们将来自在线社交网络平台推特的2015339个位置记录与大伦敦983个地区在一个月内（2014年5月）的能源消耗（天然气）进行了比较。我们的研究结果表明，回返者的人口流动网络和天然气消耗之间存在更强的统计上显著的空间依赖性，表明这一人群在城市能源使用中占主导地位。这表明，城市能源消耗的空间波动除其他因素外，还受到人类交通网络结构的影响。这些结果提供了需求方多样性及其驱动因素的清晰图景，为基于人类流动性的城市能源消耗预测模型奠定了基础。能源消耗和人员流动之间的关系是为城市地区制定有效政策的关键，从而对未来的能源使用模式做出更可靠的预测和有效的管理决策。我们的研究结果将对城市规划者、研究人员和政策制定者具有重要价值。
课程简介: As a result of population growth and urbanization, the interdependencies between infrastructure, services, and individuals in urban areas continue to increase. Urban areas already consume up to 80% of the world’s energy, and the expected population increase of nearly 70% by 2050 will drive a further rise in energy consumption. It is, therefore, vital for us to develop a better understanding of variabilities in human-related effects on buildings’ energy consumption within the urban spatial context in which they exist. Intra-city trips of urban population are undertaken as a result of individuals engaging in activities across various locations. However, people exhibit variations in their daily activities and the number of locations they visit over time. Here, we investigate the spatial interdependencies between human mobility networks of two distinct populations (i.e., returners and explorers) as an indicator of their daily activity patterns, as well as gas consumption to explore how variations in human mobility networks can be used to explain spatial fluctuations in energy use. We compare 2,015,339 positional records from an online social networking platform, Twitter, with energy consumption (gas) across 983 areas in Greater London over the course of a single month (May 2014). Our findings indicate a stronger statistically significant spatial dependency between human mobility networks of the returners and gas consumption, indicating domination of this population in urban energy use. This suggests that spatial fluctuations in urban energy consumption are governed by the structure of human mobility networks, among other factors. These results provide a clear picture of demand-side diversity and its drivers, establishing a foundation for human mobility-based predictive models for urban energy consumption. The relationship between energy consumption and human mobility is key to creating effective policies for urban areas, leading to more reliable predictions and effective management decisions about future patterns of energy use. Our findings will be of value to urban planners, researchers and policy-makers.
