Temperature-adaptive emissivity resolves the winter penalty of conventional cool-roof strategies
Tiancheng Zeng, Pengyu Zeng, Hungchen Tai, Richard de Dear, Matthaios Santamouris, Yingchang You, Xintong Ma, Borong Lin, Kaichen Dong, Shuai LuPassive radiative cooling reduces heat but cannot adapt to cold, causing a winter penalty, whereas temperature-adaptive radiative coatings (TARCs) switch modes seasonally via temperature-triggered emissivity shifts and tunable solar reflectivity.
