[19–24]. Asan and Sancaktar [19] studied the effect on the thermophysical properties of different building materials at 2.5cm thickness on time lag and decrement factor. They demonstrated large time lags of concrete block (density of ∼1.4g/cm3) that has thermal conductivity value of around 0.51W/m◦C, and brick block (density of ∼1.8g/cm3) that has thermal conductivity value of around 0.62W/m◦C
