Research on Optimization of the Thermal Performance of Composite Rammed Earth Construction

Rammed earth (RE) is a low-tech recyclable building material with good heat storage and moisture absorption performance that can better maintain the stability of indoor thermal environment improve comfort. With innovations in development new technology, field rammed construction technology gradually expanding. However, deficiencies insulation traditional structures make it impossible for them to meet China’s energy codes cold regions. This study constructs comprehensive evaluation index walls based on transfer mechanism, optimizing thickness boundary conditions interior’s design temperature, as well demand economic efficiency. research also offers by combining savings code WUFI Pro software. demonstrates optimum Beijing about 360 mm, extruded polystyrene board (XPS) 50 mm (for public buildings) 70 residential buildings), structural form external highest benefit. In addition, this work evaluates risk condensation inside composite construction, finding there exterior side wall at interface between panels wall, thus requiring an additional moisture-proof layer. study, mass are fully considered strategy given quantitatively, providing theoretical basis application materials
