Análise do desempenho térmico de uma espuma vítrea aplicada em habitação de interesse social.

Abstract

As a result of global energy expenditure, and the high consumption of residential buildings, the demand for energy efficiency in this sector is increasing. Sustainable development, which also occurs through the reduction of consumption, can be improved through new technologies and tools that assist in the control of consumption and comfort of these buildings. In this sense, the present work sought to evaluate, through computer simulation, the performance of a commercial glassy foam, when applied in a social housing, with the objective of improving the efficiency of buildings, by increasing thermal comfort and reducing the energy expenditure. For this purpose, the typology and geometry of the base object of study was defined, the modeling and configurations of the base case and the optimized cases with natural ventilation and artificial conditioning, using thermal insulation thicknesses of 2.3 cm, 1 cm and 0 , 5 cm, plus wall thicknesses of 2.5 cm, 1.5 cm and 0.5 cm. Still, 9 other combinations were made between walls and roofs, in order to verify which configurations would be more efficient. It was possible to prove that the C1P1 optimization, which has greater insulation thickness both on the roof and on the walls, obtained the best results when using natural ventilation, for the bioclimatic zone 1, characterized as a colder zone and where there are the greatest differences comfort percentages. Still, for the artificially conditioned cases, despite the lower energy expenditures, they appeared in the bioclimatic zone 3, the insulator also performed better in the bioclimatic zone 1, where, in turn, significantly reduced energy consumption.
