Outdoor seating in urban arcades plays a significant role in shaping the microclimate of these semi-enclosed public spaces. By altering airflow patterns, shading levels, and heat absorption, seating arrangements can either enhance or disrupt thermal comfort for pedestrians. Studies show that strategically placed seating can create cooler zones by promoting natural ventilation, while dense layouts may trap heat and reduce air circulation. Materials like wood or metal also influence surface temperatures, impacting localized warmth. Additionally, greenery-integrated seating can further moderate microclimates through evapotranspiration. Urban planners must balance functionality with microclimate considerations to optimize comfort in arcades, making them more inviting and sustainable for city dwellers.
