According to HKGBC Retro Fitting Guidebook updated in January 2023, Passive Radiative Coat (i.e. iPaint) was applied first introduced and applied on roof that can irradiate heat to the atmosphere to reduce the overall thermal transfer value of the building in order to reduce energy consumption of the air-conditioning system. The speakers shared their recent application of different type of passive cooling materials on building envelope for energy saving.
