论文摘要
建筑物中温室气体的减少构成了减轻气候变化影响的政策的基石。但是,由于每个城市的定制特征,都证明了满足全球城市需求所需的城市规模建筑能源建模系统的自动化。城市之间的独特性之一就是城市微气候,这可能在改变建筑物中能源效率的性能方面起着重要作用。这项研究提出了一种通过卫星读数和气候重新分析来快速收集城市微气候数据的方法。然后,我们通过对来自纽约市的三年每月建设能源消耗数据进行分析来证明该数据的潜在效用。总体而言,纽约市的小气候可能负责城市能源消耗的大量波动。我们估计中央公园可能会使相邻建筑物的电力消耗量增加5-10%,而植被总体似乎对汽油消耗没有明显的影响。我们发现,有利的城市微气候可能会使纽约某些建筑物的气体消耗量减少71%,而其他建筑物可能会增加汽油消耗多达221%。此外,微气候可能是导致区域中电力消耗量的28.6%或其他人的77%消耗量的降低。这项工作提供了一种策划全球高分辨率微气候数据的方法,使研究人员能够探索与周围建筑物相互作用的城市微气候的无形墙。
The reduction of greenhouse gases from buildings forms the cornerstone of policy to mitigate the effects of climate change. However, the automation of urban scale building energy modeling systems required to meet global urban demand has proven challenging due to the bespoke characteristics of each city. One such point of uniqueness between cities is that of urban microclimate, which may play a major role in altering the performance of energy efficiency in buildings. This research proposes a way to rapidly collect urban microclimate data through the utilization of satellite readings and climate reanalysis. We then demonstrate the potential utility of this data by composing an analysis against three years of monthly building energy consumption data from New York City. As a whole, microclimate in New York City may be responsible for large swings in urban energy consumption. We estimate that Central Park may reduce the electricity consumption of adjacent buildings by 5-10%, while vegetation overall seems to have no appreciable impact on gas consumption. We find that favorable urban microclimates may decrease the gas consumption of some buildings in New York by 71% while others may increase gas consumption by as much as 221%. Additionally, microclimates may be responsible for the decrease of electricity consumption by 28.6% in regions or increases of 77% consumption in others. This work provides a method of curating global, high resolution microclimate data, allowing researchers to explore the invisible walls of urban microclimate which interact with the buildings around them.
