VIRTUAL Barcelona Livable Cities

Abstract

Southern European cities are increasingly affected by rising temperatures and more frequent heat waves. These impacts are strongly linked to urban imperviousness, surface materials, and limited canopy coverage. In dense cities like Barcelona, where sealed surfaces dominate and green infrastructure is sparse, addressing urban heat requires rethinking the role of public space. Streets, as one of the most extensive and valuable public assets, present a critical opportunity for actionable climate adaptation strategies. This paper uses Barcelona as a case study to explore the relationship between street design and heat resilience. Through spatial analysis and urban heat mapping, this presentation identifies areas of high exposure and propose targeted design strategies. These include expanded tree canopy, permeable pavements, reflective materials, and water-sensitive infrastructure to reduce surface temperatures and improve pedestrian comfort. Drawing on comparisons with cities like Athens, Naples, and Madrid, where similar conditions produce intense urban heat, the study highlights how streets can be transformed into cooling corridors that support public health, especially for vulnerable demographic groups. The findings argue for a shift in urban design priorities. By viewing streets as multi-functional spaces rather than transit-only corridors, Barcelona can lead in building urban environments that are more adaptable to extreme heat. Strategic, street-level interventions can significantly enhance climate resilience and improve overall urban livability across the Mediterranean climate.
