Abstract

Passive cooling article () includes a plurality of first elements () defining a high absorbance in the atmospheric window wavelength range and defining high average reflectance in the solar wavelength range and a plurality of second elements () defining a low absorbance in the atmospheric window wavelength range and defining high average reflectance in the solar wavelength range, wherein the plurality of first () and second () elements are interspersed to form a major structure having a first major surface () comprising the first element outer surfaces () and the second element outer surfaces (), wherein the first element outer surfaces () face a first direction toward a first end region () of the major structure () and the second element outer surfaces () face a second direction toward a second end region () of the major structure. The article () may be applied to a substrate (), for example, on a generally vertical surface of a vehicle or stationary structure.
