Low-cost portable system for measuring thermal conductivity of building

Abstract The developed system allows to measure the thermal conductivity of solid materials used as insulators in building bioclimatic houses on high Andean zones. A unidirectional heat flow model through a sample dimensions 4.0 cm x 4.2 1.35 has been considered. K-type thermocouples were temperature’s gradient. obtained values were: 0.97 Wm −1 °C for glass, 0.38 ignimbrite, 0.58 roof brick and 0.34 adobe with Stipa ichu . These have evaluated considering their abundance use house Arequipa department
