RESUMO

The aim of this work is to describe an experimental study using castor oil foam as an insulating material inside the roof. The castor oil foam inside the roof is an appropriate natural recycled material as a passive cooling strategy as opposite to the burning of fossil fuels for air conditioning (AC) and mechanical ventilation. The expected result of this research is the possibility of contributing to improve thermal comfort and quality of life in the built environment. This experimental study is based on collecting data under real climate conditions of temperature and humidity to investigated the thermal performance in four test-cells with castor oil foam inside their roofs, in the city of Ilha Solteira located at northwest region of São Paulo State, in Brazil. In this research four test-cells constructions were used for data collection of ambient and surfaces temperatures with dimensions 3,00 x 2,00 x 2,50 m in real scale. The first test-cell was composed with insulating material like a sandwich. The second one with no insulating material was taken by reference. The third one was had insulating material on the flag and on the fourth was found the central of data collection. This work compared about the behavior in the test-cells applying castor oil foam on four different periods of the year: two on the summer and two in the winter. Results showed up the best thermal performance on the summer period was demonstrated on the test-cell no 3, presenting white roofing. Otherwise in the winter, the best thermal behavior was presented on the test cell no 1, with white roofing, too
