With rapid urbanization and increasing land scarcity, optimizing building layouts to meet residents' sunlight requirements has become crucial. This study proposes a method to analyze sunlight spacing in building clusters based on solar geometry models, aiming to improve urban planning and protect residents' sunlight rights. Focusing on Hangzhou as a case study, the apparent motion trajectory of the sun is integrated with a variable-step algorithm to calculate the minimum building spacing for different floor heights. For example, a 10-meter building height requires a minimum spacing of 13.3 meters. Furthermore, the study investigates the impact of building rotation angles on sunlight spacing, particularly in non-north-south-oriented layouts. The results demonstrate that rotation angles significantly affect sunlight distribution, highlighting the need to consider orientation in urban design. This research provides a practical framework for optimizing building layouts to balance land use efficiency and sunlight accessibility, offering valuable insights for urban planners and policymakers.
