Study of parameters of acoustic and thermal comfort of a house built with green bricks

Abstract

The proposed work consists in study and check the temperature, humidity and acoustics of a home built with green bricks, made of soil, cement and water, in Guaratinguetá-Brazil, to compare and show benefits in the aspects of acustics, thermal, energy and residual, compared to conventional buildings. Is also made the calculus of the amount of such bricks. This kind of construction is typical of tropical regions, like Brazil, because of your thermal benefits. The instrumentation of the house was made using temperature meters, moisture meter, sound level meter, anemometer and density meter solar power. Was collected the temperatures, moisture content, wind speed and solar radiation at different periods. On a day with sunlight 130,4 W / m², the outside temperature was 24,4 ° C and internal temperature was 26,6 ° C and the wind speed was 1,1 m/s. Already on days with higher solar radiation 891W/m², the outside temperature was 30,8°C and the internal temperature was 24,4°C, and the wind speed was 0,7 m/s. The results was positives, the green bricks provided the benefits mentioned above, showing that this type of construction can benefit society and the environment, encouraging their use.
