摘 要:This paper presents a prediction of thermal behavior of bioclimatic building by the mean of time lag. Firstly, we provided locally made materials with commonly known thermal properties. Afterwards, we conducted a simulation of a building free of internal charges on the TRNSYS 16 (Transient system simulation) platform. This simulation has focused on the collection of thermograms concerning the inside and outside surfaces (exposed to solar radiation) temperatures of walls oriented South, East, North and West on the basis of a weather file called Meteonorm. An analysis of the results was conducted which leaded to the conclusion that time lags of East oriented walls is greater than that of the other walls. Furthermore, the simulation confirms that the lower the value of thermal diffusivity is, the greater the corresponding time lag is. Finally, the results of the investigations revealed that the locally designed materials have greater time lag than that of commonly use materials, like concrete. Therefore, they consume less energy as construction materials.
