Influence of urban morphology on facade solar potential in mixed-use neighborhoods: Block prototypes and design benchmark
https://orcid.org/0000-0001-9627-4724
Highlights Walls have significant solar potential despite receiving less solar radiation than the roof areas. Quantifying the solar potential of building facades in different urban forms is an important task. This study explores the façade solar potential of different block types in Adelaide. It simulates solar potential of building rooftops and facades across city boundaries. Five prototypes are identified to provide a benchmark in the early urban planning and design stage.
Abstract The decarbonization of urban energy systems relies heavily on Building Integrated Photovoltaic (BIPV) technology, which harnesses solar energy from building envelopes. While rooftops have been the focus of solar potential studies, walls also hold significant potential despite receiving less solar radiation. This study aims to quantify the solar potential of building facades in various urban forms, using Adelaide as an example. It first simulated and predicted the solar radiation potential of building facades, then conducted a cluster analysis of urban morphology factors and wall solar potential based on parameters chosen from existing studies to yield five clusters. Five block prototypes were identified for deploying solar on the walls in mixed-use urban neighborhoods. The solar potential was evaluated by calculating the electricity output from solar photovoltaic systems. The results indicate that the ranking of the solar potential of walls from highest to lowest is Cluster 4 (low density and nonuniform size, 1079.83 kWh/m2/year), Cluster 5 (low-rise, low density and uniform size, 1048.83 kWh/m2/year), Cluster 2 (low-rise and high density, 1027.80 kWh/m2/year), Cluster 3 (high-low mixed rise and high density, 985.59 kWh/m2/year), and Cluster 1 (high-rise and high density, 926.16 kWh/m2/year). The rooftop solar potential in Adelaide is capable of meeting the electricity demand, while the total facade solar potential in the entire city can reach 76% of the electricity demand. Specifically, the facade solar power generation of commercial buildings can account for 28% of the electricity demand, and the façade solar power generation of residential buildings can reach 39% of the electricity demand. The results of this study provide a simplified process to explore the solar potential of building facades and rooftops in different block types, which may provide a design benchmark for mixed types of blocks with high solar potential in the early phases of city planning and building design.
