Abstract

The disordered anthropic action results in harmful consequences as climatic changes; used up of energy sources no-renewable; urban canyon, responsible for the energy demand to use in building refrigeration, among others. Mainly in the case of Brazil, for the abundance of the solar radiation annual exposition, the behavior of these building surfaces is determinative to energy saving, to develop energy efficient buildings and to improve the quality of human life. In this direction, the present research considers to investigate the attenuation potential of each roofing system of passive cooling and its contribution in the energy saving. Seven cement with synthetic fiber roofing going to monitored - CRF in models reduced with the use of the passive cooling: three simultaneous cycles of water spraying, low emissivity and high reflectance coats. They going to monitored in the test-cell: internal roofing surface temperature, air inside temperature and air inside relative humidity, coatings reflectance and emissivity, heat flow in roofing. In your research’s Master, some results of the cooling roofing passive systems had been presented. (AU)
