Alterações da temperatura em ambientes externos de favela e desconforto térmico Temperature modifications in shantytown environments and thermal discomfort RESUMO

OBJECTIVE: To study aspects of the microclimate in a shantytown (favela), in order to understand the influence of the land occupation pattern on its climatic parameters. METHODS: The study was carried out in a shantytown located in the southwestern region of the city of São Paulo, Brazil, between February 19 and July 31, 2003, i.e. covering the whole autumn and parts of the summer and winter. The air temperatures were measured every hour on a microclimate scale, at four points within this densely populated shantytown and, as a control, on a tree-lined street nearby. RESULTS: In the summer, the average hourly temperatures in the shantytown were between 18.5°C and 29.5°C but, away from it, they were 2°C to 3°C lower at the Edelci Nunes da Silva
