Abstract

Nowadays people spent a lot of energy to reduce the temperature of walls buildings, by the use of air conditioner. There are a several solutions using green technologies to save energy, so we need to characterize this kind of greens technologies. Speckle interferometry is proposed to determine the variation of temperature on green buildings that relate the efficient use of energy spending in thermal comfort. There is a disadvantage to using thermal resistors sensors for the analysis of a wall area of sustainable technology, because these items can only measure a very small area, and it is very slow to make a average measurement of several points to have an estimate of the temperature. The analysis by speckle is favorable because it is very sensitive to any change made on a surface and this allows us to record the less obvious variation in the transmission of heat, as we can manipulate to measure considerable size areas. The use of speckle is more affordable and improve less economical resource than other methods.
