Controlling building thermal environment is an important problem nowdays with many growing cities around the world. More growing cities means more buildings that make the temperature of the environment rise. The thermophysical behavior of this phenomena depends on wall’s thermal properties of wall such as: thermal conductivity, thermal mass, and solar absorbance. This paper presents the results of studies on a wall’s thermophysical behavior with variation of wall’s thermal properties. Simulation carried out by detecting temperature distribution data of wall using Energy2D simulation program of 11 cm thick wall with the area of 1m x 1m, where the wall was exposed to a heat source for 4 hours then the heat source will be turned off for 4 hours. Thermal conductivity, thermal mass, and solar absorptance of wall was varied based on brick wall as the reference wall. The measurement results show that absorbance of the wall determine the amount of heat distributed around the wall, while thermal conductivity and thermal mass of wall determine heat distribution. We conclude that controlling wall’s thermal properties will give specific impact on building thermal environment.
