Active temperature control devices are widely used for the thermal management of enclosures,including vehicles and buildings.Passive radiative cooling has been extensively studied;however,its integration with existing actively temperature regulated and decorative enclosures has slipped out of the research at status quo.Here,we present a photonic-engineered dual-side thermal management strategy for reducing the active power consumption of the existing temperature-regulated enclosure without sacrificing its aesthetics.By coating the exterior and interior of the enclosure roof with two visible-transparent films with distinctive wavelength-selectivity,simultaneous control over the energy exchange among the enclosure with the hot sun,the cold outer space,the atmosphere,and the active cooler can be implemented.A power-saving of up to 63％for active coolers of the enclosure is experimentally demonstrated by measuring the heat flux compared to the ordinary enclosure when the set temperature is around 26℃.This photonic-engineered dual-side thermal management strategy offers facile integration with the existing enclosures and represents a new paradigm toward carbon neutrality.
