“…Thus, different studies integrated building envelope solar access and urban wind patterns analyses (Figure 7) to investigate optimal urban patterns for building occupants and outdoor livability [30,60]. A particular type of research method on urban patterns is one that analyses existing urban environments [65,66]. Although it does not involve form generation, urban patterns and density, building types are investigated in relation to solar access, which has a direct influence on indoor environmental quality and energy use, to obtain indications for future developments, deep renovations and developments of new urban form indicators.…”

Researchers, architects and planners are increasingly urged to develop and apply sustainable methods and solutions to reduce the impact of the built environment on climate, adapt cities to climate change and reduce or eliminate resource depletion and building-related carbon emissions. In recent years, taking advantage of state-of-the-art computational and environmental design tools, researchers and designers are developing new digital workflows, methods and solutions to investigate climate-optimal and performative buildings and urban forms. This perspective paper analyses state-of-the-art computational methods; form generation processes; and tools, criteria and workflows that present how these are integrated into climatic form finding, allowing the improvement of building and urban environmental performances. Additionally, current challenges and future directions are presented.

“…Besides rooftops, façade surfaces can also be estimated for solar potential [10][11][12]. At high latitudes, building façades are characterized by solar potential comparable to that of rooftops during the transitional seasons [13,14]. 3D city models support the assessment of solar potential in 3D space, enabling more accurate and visually clear simulations [15][16][17].…”

Solar radiation impacts diverse aspects of city life, such as harvesting energy with PV panels, passive heating of buildings in winter, cooling loads of air-conditioning systems in summer, and urban microclimate. Urban digital twins and 3D city models can support solar studies in the process of urban planning and provide valuable insights for data-driven decision support. This study examines the calculation of solar incident radiation at the city scale in Sofia using remote sensing data for the large shading context in a mountainous region and 3D vector building data. The building footprints and the terrain are preprocessed using GIS. The solar calculation uses a raytracing algorithm in 3D CAD at the city scale. To evaluate the performance, two cases were considered at the city and district scale, respectively. The total face count of meshes for the simulations constituted approximately 2 000 000 faces. 64379 roofs for the whole city and 4796 buildings for one district were selected. All calculations were performed in one batch and visualized in a 3D web platform. Using a 3D CAD environment establishes a seamless process of updating 3D models and simulations while preprocessing in GIS ensures working with large-scale datasets. The proposed method showed moderate computation time for both cases and could be extended to include reflected radiation and dense photogrammetric meshes in the future.
