Abstract: Structural–functional integrated materials are one of directions of rapid development for saving-energy materials. Phase Change Materials (PCMs) are latent thermal storage materials possessing a large amount of heat energy stored during its phase change stage. Porous lightweight aggregate (LWA) can serve as the carrier for PCM. In this research, a structural concrete with function of indoor temperature control were prepared by using macro encapsulated PCM–LWA. The indoor and outdoor tests were performed to determine the thermal performance of the lightweight aggregate concrete (LWAC) containing macro encapsulated Paraffin–LWA. The compressive strength and shrinkage strain of LWAC with macro encapsulated PCM–LWA were evaluated. Finally, the economic and environmental aspects of application of macro encapsulated Paraffin–LWA in a typical floor area of public housing rental flat in Hong Kong were assessed.
