This paper examines the impact of mitigation measures on the Urban Heat Island (UHI) phenomenon in Modena, Italy, as part of the EU-HHI Project. The study focuses on a pilot area within the Villaggio Artigiano, an industrial area undergoing urban redevelopment. Using the RayMan model, which estimates bioclimatic discomfort based on the human radiative budget, the authors simulate the effects of introducing greenery and modifying building heights. The results show that the insertion of trees significantly reduces thermal discomfort, particularly during the hours after sunrise and before sunset due to the shadow effect. The replacement of asphalt with grass also improves thermal comfort, though to a lesser extent. The study highlights the importance of green areas in mitigating UHI and suggests that such interventions are cost-effective and effective in enhancing thermal comfort. The involvement of local stakeholders and the collaboration between scientific and administrative partners are crucial for the successful implementation of these measures.This paper examines the impact of mitigation measures on the Urban Heat Island (UHI) phenomenon in Modena, Italy, as part of the EU-HHI Project.
