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. Abstract Image

为净零能耗城市优化城市街区形态：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起着至关重要的作用，而太阳能潜力又直接影响到光伏发电能力和净零成果的实现。本研究以墨尔本市为重点，调查不同城市密度下的太阳能利用情况，并提出优化形态建议。分析涵盖了不同人口密度的街区，考察了中密度和高密度地区。通过利用多目标遗传优化方法，对这些街区的城市形态进行了改进。研究结果表明，低密度街区的光伏发电潜力是其总能耗的 1 到 6.6 倍。中密度和高密度区块的光伏发电潜力大约相当于其总能耗的 40%-85%。此外，在中密度和高密度区块内的不同城市形态中，光伏发电潜力也有很大差异。我们提出了一种 "带中央山谷的高架角 "原型，它是一种有效的方法，可将整体光伏潜力提高约 14%。这项研究引入了新的分析概念，揭示了城市形态与光伏潜能之间错综复杂的关系。

期刊介绍： Building Simulation: An International Journal publishes original, high quality, peer-reviewed research papers and review articles dealing with modeling and simulation of buildings including their systems. The goal is to promote the field of building science and technology to such a level that modeling will eventually be used in every aspect of building construction as a routine instead of an exception. Of particular interest are papers that reflect recent developments and applications of modeling tools and their impact on advances of building science and technology.
