Abstract
Global climate change is today’s biggest threat, encompassing rising extreme temperature events. The increase in the thermal mass of the building envelope by adding phase change material (PCM) is one of the promising measures to improve the thermal performance of buildings. In this study, a calcium carbonate (CaCO3) coated PCM-impregnated recycled concrete aggregate (PCM-RCA) is developed by immersion and injecting carbon dioxide (CO2) techniques. Two concrete samples using RCA and PCM-RCA aggregate are prepared and compared their thermal performance in building envelopes through EnergyPlus simulation for Sydney, Australia. The results showed that using PCM-RCA concrete in exterior walls could reduce the peak indoor air temperature by 1 °C and have an energy savings of 14.2% compared to the reference house.
