Abstract	Heat gain in buildings is identified as one of the major causes of solar radiation, resulting in indoor discomfort and increased energy demand. This study examines the role of adaptive facades in reducing solar radiation in the composite climate of Indore, characterised by strong seasonal variations. Through sun-path analysis and identification of solar geometry, climate-responsive facade conditions that tackle incident radiation, seasonal sun angle shifts, and low-angled east-west exposure are identified. Studied facade typologies are categorised into static, rotating, folding, and sliding based on their adaptation mechanisms and material configurations, followed by a qualitative framework that evaluates six criteria, namely, cut-off efficiency, relative radiation blockage, seasonal responsiveness, east-west performance, user control, and maintenance complexity. The study concludes with a suitability matrix, offering a structured basis for selecting adaptive facade strategies in a composite climate of Indore.
