Cooling demand in buildings accounts for a significant portion of global energy consumption and is estimated to increase tenfold by 2050. Daytime radiative cooling shows great potential for reducing surface temperatures and cooling energy consumption of buildings by dissipating heat into cosmic space without consuming any energy. However, further commercial application of radiative cooling technologies requires improvements in their cooling efficiency, reduction of manufacturing costs, and optimisation of their seasonal suitability. Meanwhile, typical daytime radiative coolers with constant solar spectral reflective and mid-infrared emissivity cannot automatically switch off in cold winter and would lead to an energy penalty for heating. To overcome the above limitations, this paper reviews the types of daytime radiative coolers in terms of their structure and related temperature-adaptive control methods. The literature is also analysed to compare and evaluate the performance indicator
