Spectrally Selective Thermal Radiation Management for Effective Temperature Control and Climate Adaptation

The demand for space cooling and heating has surged with the development of technology, posting a global challenge that requires sustainable thermal management solutions. Spectrally selective thermal radiation management stands out as a particularly promising approach due to its zero-energy consumption feature. This review first examines the specific scenarios where thermal demand applies and evaluates the theoretical energy-saving potentials of radiative cooling (RC), solar heating (SH), and dynamic radiative cooling (DRC) technologies. Subsequently we outline the operational principles and recent progress in various innovative research areas. Additionally, we explore the broad prospects of spectrally selective thermal radiation management in addressing urban heat island effects, advancing green energy initiatives, facilitating water desalination, and improving energy effectiveness across diverse applications. This review identifies major challenges and emerging opportunities for future research, offering an in-depth guide to advancing the frontiers of sustainable thermal management technologies.
