Abstract

The morphology of urban areas plays a crucial role in determining solar potential, which directly affects photovoltaic capacity and the achievement of net-zero outcomes. This study focuses on the City of Melbourne to investigate the utilization of solar energy across different urban densities and proposes optimized morphologies. The analysis encompasses blocks with diverse population densities, examining medium and high-density areas. By utilizing a multi-objective genetic optimization approach, the urban morphology of these blocks is refined. The findings indicate that low-density blocks exhibit photovoltaic potential ranging from 1 to 6.6 times their total energy consumption. Medium and high-density blocks achieve photovoltaic potential levels approximately equivalent to 40%–85% of their overall energy consumption. Moreover, significant variations in photovoltaic potential are observed among different urban forms within medium and high-density blocks. An “elevated corners with central valley” prototype is proposed as an effective approach, enhancing the overall photovoltaic potential by approximately 14%. This study introduces novel analytical concepts, shedding light on the intricate relationship between urban morphologies and photovoltaic potential.

优化净零能源城市的城市街区形态：探索光伏潜力和城市设计原型

摘要

城市地区的形态在决定太阳能潜力方面发挥着至关重要的作用，这直接影响光伏发电能力和净零成果的实现。本研究重点关注墨尔本市，调查不同城市密度的太阳能利用情况，并提出优化的形态。该分析涵盖人口密度不同的街区，检查中密度和高密度区域。通过利用多目标遗传优化方法，这些街区的城市形态得以细化。研究结果表明，低密度街区的光伏潜力是其总能耗的 1 至 6.6 倍。中密度和高密度街区的光伏潜力水平大约相当于其总能源消耗的 40%–85%。此外，在中密度和高密度街区内的不同城市形态之间观察到光伏潜力的显着差异。提出“中央山谷高角”原型作为一种有效方法，可将整体光伏潜力提高约 14%。这项研究引入了新颖的分析概念，揭示了城市形态与光伏潜力之间复杂的关系。
