Abstract

Urbanization is defined as the physical growth of urban areas. About half of the world's population now lives in cities and expected that this amount will increase to 61% by 2030; this growth will be more pronounced in developing countries. Cities are the habitat for excellence of human, and present environmental characteristics (urban climate) common in many parts of the world, as for example the presence of the island of urban heat (ICU). The urban heat island reveals the impact of habitat built on the physical environment and the increase in temperature that produces. Climatic change effects and the processes of urban growth caused environmental deterioration in the city of Buenos Aires. The increase of the temperature according to the models established by the Intergovernmental Panel on climate change could emphasize over the next decades. For Buenos Aires the models predict, specifically in the 2020-2029 period, an increase of average maximum temperatures in 0.6°C to 2° C (for the minimum temperature average). One of the proposed solutions is the green roof, which, mainly can help as buffer against temperature extremes and the urban heat island. The objective of the present study was to determine, for the climatic conditions of the Autonomous city of Buenos Aires (CABA), if the moisture content of the substrate of green roof due to rains, has influence on the thermal regulation. The results obtained allow us to conclude that for the conditions of the study site and in the analyzed months, the Vegetated Roof (CV) allows a regulation of the temperature inside the building (on average) of around 2 degrees Celsius. However, statistically significant differences could not be verified on days with rain.
