Methods and Techniques for Integrated Mesoscale and Microscale Analysis of Urban Thermal Behavior: The Case of Bari (Italy)

Within the general study of urban heat islands, some specific aspects were investigated in the city of Bari, South Italy, where the analyzes were carried out at two different scales, in order to explore the thermal patterns of all the areas including public housing complexes. In fact, it was considered that those are among the most vulnerable to urban and building decay, also due to poor original environmental and constructional quality, so that improvement actions at different decision-making levels are highly desirable. Specifically, starting from a GIS-based analysis of the overall urban area at the mesoscale, through some representative parameters and their relationships with the land surface temperatures, the assessment was further carried out at the microscale, which suggested retrofitting strategies on the buildings, in order to address both district heat mitigation and envelope energy efficiency.
