Building Materials And Indoor Thermal Environment Of Vernacular Houses In South Of Shaan Xi

Protecting environment and keeping sustainable development is the important responsibility which is faced by ours world, in our country it is very urgent. The vernacular houses in south of Shaan Xi have some typical characters which is belong to the Chinese traditional architectures. The envelope structure use the local building materials and need less energy to make it. The materials could be made use of cyclically, it has less bad influence to environment, so it is the vernacular ecological architecture. In the basis of the excellences, we studied the thermal transfer and the moisture transfer of envelope structure.Though the laboratory experiments and the field measurements we acq -uired some experiences and technologies about the vernacular ecological architecture, and explained the science essence of it. It could be used to guide the local people to better building which is satisfy the ecosystem and traditional culture and to make a sustainable development.On the base of survey the paper presents the thermal physical parame ters and the moisture transfer properties of the building materials, investig ate the indoor thermal environment.As the one hand data, it is the foundation of the further research. Data of the tamped clay material is the first tested in our country. Equilibrium moisture content curve we measured gives good agreement with the result drew by D.M Burch, it prove that is valuable for utility. The relation between the conductivity and moisture content can be used to predict the moisture content of thematerials. It is obvious that indoors thermal environment in summer and winter of camped clay building is better than that of the brick building through the field measurements.
