Shape-stabilized phase change material (SSPCM) was prepared by impregnating hexadecane, as a PCM, into xGnP, as a supporting material. Fourier transform infrared spectroscopy confirmed that the heat storage characteristics of hexadecane could be integrated into the structure of xGnP for its physical bonding, without a change in its chemical properties. Differential scanning calorimeter analysis showed that the melting temperature range of the SSPCM was similar to that of pure hexadecane. Thermo gravimetric analysis of the hexadecane/xGnP SSPCM determined that the percentage of impregnated hexadecane into xGnP was 48.8 % with 96.4 J/g of latent heat storage energy. In addition, mortar with the prepared SSPCM was investigated in terms of developing advanced building materials with thermal energy storage properties. The heating and cooling behavior test of the SSPCM mortar demonstrated the improvement of the thermal mass and inertia by the mortars containing the SSPCM. Consequently, the thermal behavior of the test buildings made of the hexadecane/xGnP SSPCM mortar was computationally investigated using Energy Plus. The obtained measurements validated a reduction in temperature variations and an enhancement of thermal inertia, during the time periods examined. Consequently, the thermal behaviors of the test buildings made of the hexadecane/xGnP SSPCM mortar were computationally investigated using Energy Plus. The measurements obtained demonstrated a reduction in temperature variations and an enhancement of thermal inertia, during the monitored time periods, when the wall is treated with the SSPCM mortar. Hence, an improvement in indoor comfort and a reduction in building energy consumption can be anticipated. The utilization of the new composite SSPCM considerably contribute to the thermal energy storage rate in buildings.
