| Abstract |
The deployment of solar energy is among the key strategies to counterbalance the increasing energy consumption and greenhouse gas emissions in urban areas, contributing to a sustainable built environment. In this context, interactive platforms such as solar atlas, mapping, and cadasters play a primary role by enabling the evaluation of urban solar energy potential. Solar cadasters, in particular, facilitate user interaction for early exploration and pre-design of solar installations. This study presents a comprehensive − non-exhaustive − database of solar cadasters, focusing on interaction, accuracy, and degree of customization of solar data. The scale and level of detail of the geometry model, as well as the visualization of solar metrics on analyzed surfaces, are investigated. Solar cadasters mostly investigate the urban scale, with a medium–high level of detail of the geometry models and a gradient visualization of the solar data. Additionally, the functionality of solar cadasters is examined, identifying design input parameters and the estimated energy, technical, economic, and environmental metrics. Based on the results, future solar cadasters should enhance the calculation of the building solar potential, with a specific focus on facades, taking into account inter-building reflections and material properties. Additionally, user experience, data visualization, accessibility, and interoperability of solar cadasters with urban planning tools should be improved. This research is relevant for developing informed decision-making to accelerate urban clean-energy transitions, support innovation, increase public and private stakeholder engagement on solar energy systems adoption, and contribute to achieve targeted Sustainable Development Goals in high- and low-income countries. © 2024 The Authors |
