Abstract: This study investigates the environmental parameters that contribute to the Urban Heat Island (UHI) effect in historic environments, with a particular focus on the UNESCO World Heritage City of Matera. The complex urban morphology of Matera, with its narrow streets and underground buildings, generates distinctive microclimates that intensify the UHI phenomenon, posing challenges for urban planning and heritage conservation. The main objective of the research is to identify which environmental parameters interact with Matera’s architectural and urban characteristics to intensify the UHI, and to propose mitigation strategies that balance heritage conservation with environmental sustainability. The research follows a mixed methodological approach in two phases. The first phase consisted of a comprehensive literature review, identifying gaps in previous studies and developing a methodological framework combining quantitative and qualitative techniques. The second phase involved empirical analysis using advanced techniques such as 3D laser scanning to model urban morphology, satellite image analysis to map the spatial distribution of the UHI, and the integration of historical and real-time meteorological data. The results show significant correlations between urban morphology and UHI intensity, suggesting strategic interventions such as green roofs and reflective materials to mitigate the effects. These findings provide valuable information for urban planners and policy makers, and highlight the importance of integrating sustainable approaches into heritage conservation.
