Optimized cool roofs: Integrating albedo and thermal emittance with R-value [PDF]
, 2011 For cool roofs the combined effect of the three parameters that define heat gain and loss from a roof, namely solar albedo α, thermal emittance E, and sub-roof R-value, must be considered. An accurate contribution of night sky cooling, and hence humidity

CLAY ROOFING TILE: A COOL ROOF?
Open Journal of Science and Technology, 2018 The aim of this study is to determine if the clay roofing tile in its natural albedo can be considered “cool†in the thermal performance through a comparison of its surface temperature to a cool coated clay tile using the exposure rack method. It begins with highlighting the expectation (from review) of the thermal performance of a cool colored ...
