Abstract. This study investigates using BIM for solar path and shadow analysis to enhance energy-efficient building design in the tropical climate of Dhaka, Bangladesh. It focuses on a site area of 6910 m² in Mohammadpur, aiming to optimize solar gain, minimize unwanted heat, and improve natural daylighting in buildings. Utilizing tools like SketchUp with Skelion and Curic Sun, detailed analyses of solar paths and shadows were conducted for key dates across different seasons. The findings demonstrate that strategic building orientation, site layout, ventilation, and the implementation of shading devices can significantly enhance energy efficiency, reducing both heating and cooling demands throughout the year. Moreover, the study underscores the importance of integrating solar and shadow data into the design process to develop sustainable buildings that balance functionality with energy conservation. These results offer valuable insights and practical guidelines for architects and engineers aiming to promote sustainable building practices.
