- Abstract:
- The high rate of energy consumption in the building sector has led the designers towards the construction methods that consume less energy during construction up to serviceability. One of these methods is rammed-earth (RE) structures due to the availability of its materials, ease of preparation, considerable decrease in energy consumption and environmentally-destructive consequences. Improving the thermal characteristics besides the mechanical parameters of RE structures develops the application of this method. In the current study, the dynamic thermal parameters of RE wall specimens were experimentally measured under simulated conditions and compared to those of masonry walls. Thereby, a hygrothermal chamber was designed and made and Fourier’s law was used to determine the thermal conductivity of these materials. Moreover, the effect of the acrylic coating was investigated for increasing thermal mass and thus, decreasing energy loss from the structural elements. The results illustrate the proper thermal performance of stabilized rammed-earth in comparison to the masonry materials besides the positive effects of acrylic coating which leads to the satisfactory thermal comfort limits based on ASHRAE 55 standard
