摘　　要：当前城市建筑的屋顶、立面存在着大量闲置空间。有效利用这些空间进行太阳能发电,可满足城市一定量的能源需求。选取屋顶和立面的光伏系统应用潜力为研究方向,综合城市空间形态和建筑功能,使用参数化建模与分析工具,构建了一套适用于推算城市建筑空间光伏潜力的流程方法。该方法运用于天津市中心城区,按400 m×400 m划分城市网格,运用采样法从中遴选出12个样本区域,模拟计算各样本区域的光伏潜力,进而推算城市尺度的总体光伏潜力。结果显示,天津市中心城区总体光伏潜力为6561.85 GWh/a,其中屋顶和立面的光伏发电值分别为2854.06 GWh/a、3707.79 GWh/a,可满足天津市总人口电力消耗的166%。运用该评估方法能够较为快速准确地计算城市建筑空间的光伏发电潜力,研究结果可为同类城市建筑空间的光伏技术应用决策提供参考。Urban buildings often harbor substantial unused spaces on rooftops and facades.Harnessing these areas for solar energy generation has the potential to fulfill a significant portion of urban energy requirements.This study focuses on the latent photovoltaic(PV)capacity of urban rooftops and facades,synthesizing considerations of urban spatial configurations and architectural functionality.Utilizing parametric modeling and analytical tools,we have developed a systematic methodology tailored to estimate the PV potential of urban architectural spaces.Applied to central Tianjin,the city was partitioned into a grid with 400m×400m cells,within which 12 representative sample regions were selected using a sampling approach.The PV potentials for these areas were simulated,facilitating an extrapolation to a city-wide PV capacity estimate.The findings reveal that the central urban area of Tianjin has an aggregate PV potential of 6561.85 GWh/a,with rooftop and facade PV generation capacities accounting for 2854.06 GWh/a and 3707.79 GWh/a,respectively.This capacity could satisfy 166%of the electrical energy demands of Tianjin’s population.The proposed assessment method offers a swift and precise evaluation of the PV generation potential in urban architectural spaces.The outcomes of this research provide valuable insights for policy-making and strategic planning for the deployment of PV technology within comparable urban settings.
