Abstract

Pigment colorant researchers are developing new complex inorganic color pigments that exhibit dark color in the visible spectrum and high reflectance in the near infrared portion of the electromagnetic spectrum. The new pigments increase the near infrared reflectance of exterior finishes and paints, thereby dropping the surface temperatures of roofs and walls, which, in turn, reduces the cooling-energy demand of the building. However, determining the effects of climate and solar exposure on the reflectance and the variability in color over time is of paramount importance for promoting these energy efficiency benefits and for accelerating the market penetration of products using the new color pigments.
