Outdoor seating plays a significant role in shaping the microclimate of urban hypogea—underground or semi-underground urban spaces. By altering airflow, shade patterns, and heat absorption, seating arrangements can either mitigate or exacerbate temperature fluctuations in these environments.

The presence of benches, pergolas, or other seating structures affects solar radiation exposure, reducing heat buildup in summer while allowing passive warmth in winter. Materials like wood or metal also influence thermal conductivity, impacting localized comfort. Additionally, greenery-integrated seating can enhance evaporative cooling, improving humidity levels.

Urban planners must consider these factors to optimize hypogea microclimates, ensuring thermal comfort for pedestrians while minimizing energy costs for climate control. Strategic placement and material selection are key to balancing aesthetics and functionality in underground urban spaces.
