Adaptive Facades as Urban Interfaces: A Conceptual Framework for Typologies and Urban Impacts

Today, climate change, increasing energy consumption, and advancing technologies necessitate that building façades be considered not merely as static envelopes separating indoor and outdoor environments, but as dynamic systems that respond to changing conditions. In this study, adaptive façades are examined beyond technological systems that improve building performance, as urban interfaces establishing environmental, spatial, visual, social, and technological relationships between buildings and cities. Based on a comprehensive literature review, adaptive façades are classified into five main categories: mechanical, material-based, biological, digital, and hybrid. The effects of these systems on energy consumption, urban microclimate, public space quality, user experience, urban identity, and smart city infrastructure are then qualitatively compared. The conceptual framework developed reveals that the selection of adaptive façades should consider not only their technical performance at the building scale but also their multidimensional impacts at the urban scale.
