Urban overheating significantly affects thermal comfort and livability, making it essential to understand the relationship between urban form land surface temperature (LST). While horizontal dimensions of have been widely studied, vertical structures their impact on LST remain underexplored. This study investigates influence three-dimensional characteristics LST, using ECOSTRESS sensor data four machine learning models. Six morphology variables—building density (BD), mean building height (MH), volume (BVD), gross floor area (GFA), ratio (FAR), sky view factor (SVF)—are analyzed across different seasons times day. The results reveal that MH, BD, FAR are season-stable factors, with higher MH correlated lower ((e.g., an observed reduction approximately 3 °C in spring), while BD is associated (e.g., increase about 3.5 autumn). In contrast, BVD, GFA, SVF season-varying factors variable impacts depending time year. Higher BVD generally elevated GFA linked LST. These associations reflect absolute changes measured directly from data. findings offer valuable insights into complex interactions helping inform strategies for heat mitigation sustainable planning.

This paper proposes an origami-based adaptive façade for reducing potentially harmful reflected solar radiation in outdoor urban environments. The Walkie-Talkie building London is selected as case study due to numerous reported incidents related the excessive of building. performance peak at pedestrian level investigated by means computer simulations. simulations are based on hourly irradiance between 10AM and 14 PM a day August. Initially 10 different folded states three Miura-fold origami units were adopted, simulated with 15-minute intervals each state. results showed that, best performing can reduce 61% average, up 90% depending specific state time day.
