Hydro-thermal Analysis of Building Envelope Walls with Cement-Stabilized Rammed Earth Structural Layer and Different Thermal Insulators and Their Positioning in Humid Continental Climate

The objective of the work is to analyse thermal insulation positioning in a building envelope wall with a load-bearing layer made of cement stabilized rammed earth (CSRE) in a humid continental climate. In the article CSRE is described and recommendations regarding the wall thickness of this material are presented. The results of the CSRE coefficient of thermal conductivity and current standard values of the heat transfer coefficient for external walls in various countries of a humid continental climate are also presented. On this basis, the thickness of the necessary thermal insulation in building envelope partitions with a load-bearing layer of CSRE is estimated. In the latter part of the article, the results of the simulation of hydro-thermal conditions occurring in partitions with a load-bearing layer of CSRE insulated with different types of thermal insulation placed in different parts in the partition are presented. The simulations have shown that in a humid continental climate the best solution is the use of thermal insulation on the external side of the building envelope. (paper)
