Abstract

The urbanization process can influence the local climatic conditions, influencing city's thermal field and energy consumption for the air conditioning of buildings. In this sense, this work seeks to identify areas with potential for heat and cooling island formation in Porto Alegre/RS. The estimation of surface temperatures was based on Landsat-8 satellite images. A hot spot and cold spot analysis were performed to identify the most susceptible areas. It was possible to identify the city's most critical areas in heat and cooling island formation considering summer and winter scenarios.
