Abstract: Phase change materials (PCMs) integration into cement mortar is among the new studies of interest regarding modern energy-saving techniques and developing the thermal properties in buildings. This study aims to integrate microencapsulated-PCMs (micro-PCMs) with cement mortar at 0, 5, 10, and 15% to replace natural sand for thermal properties improvement of the building envelope. In addition, the effect of using micro-PCMs on mechanical, thermal properties, and PCMs leakage problems were studied. The cement mortars incorporated with micro-PCMs were investigated by scanning electron microscopy (SEM), thermal conductivity, and mechanical properties as (compressive, flexural, and tensile). The results indicate a decreasing trend of thermal conductivity values with the increase in PCMs content in the cementitious system with the percentages of 11, 21, and 30% for 5, 10, and 15% PCMs, respectively. Similarly, mechanical properties results also confirmed that integrating incorporating mortars with PCMs resulted in the reduction in the compressive strength by 22, 31, and 46%, respectively. Therefore, using the PCMs with cement mortar can build envelope applications to store thermal energy, provide the indoor temperature at a comfortable range, and reduce the consumption energy in buildings.
